My father was the original owner of this car. I have so many memories driving with him in this 850. I was the 2nd owner. Thank you for putting in the effort to bring her back up to snuff. So cool to see this video!
As an 850 owner of 12 years, the drain problem solution is literally a 30 second google search away, and would cost you 10usd in capacitors, 15 minutes to remove unit from the car and 30 minutes with a soldering iron. This car CAN be fixed, but not at a shop as they are useless on old cars like these. Get on the forums where the real knowledge is, there are people on the forums who have owned these cars for 15+ years, and there is NOT A THING that the community don't know how to fix. And if you can't work on it yourself, alt least you know what to tell you mechanic to fix.
this guy is on it..... the caps swell up on the PCBs ... replace all Capacitors not just the ones that look or test bad. shops dont do componenet level repair anymore...got to DIY
It's a well known issue with the GM2 and RM5 modules on these cars. The caps dry out and change their value just enough for the car not going to "sleep" after 16 minutes. You are left with a 4-500mA drain instead of a 50-60mA. leading to flat batteries in 7-10 days, rather than 4-5 months. In very rare cases there has been a drain from the one of the door locks too. 30 second google search an a DIY pops up. Owning a car like this means you are more lightly to get help in the community than in a shop, heck, most BMW techs have never seen any of these cars.
WPWBigCheese probably not. To busy making videos, doing his day job and searching for useless techs ro waste more money on scans and quasi-diagnosis that don't lead anywhere. Some people think that because AutoZone does free scans then so do techs.
1) PLEASE don’t ever jump this car from the batteries again. Sure fire way to cause electrical damage. only jump it from the terminals under the hood. 2) your electrical draw issue can likely be resolved for around $100. It is the capacitors in the general module. They need to be replaced. 3) Did the mechanic test the seat motor to ensure it’s actually the motor itself? Often times the cables get out of whack on the seats and prevent them from moving properly even though the seat motors (which are very robust) are actually working. There are replacement cables available for under $200. We have to remember these are 25 year old cars that very few people know how to work on now because of their rarity. However, there is a huge group of enthusiasts that k ow how to fix them and are willing to help fellow owners. If you are interested in more details on how to get her completely healthy, feel free to reach out to me directly.
The engine is 2 engines in one. However the m70 and m73 are both considered very bullet proof … added complexity requires replacing some items down the road. These are like an airplane that periodic maintenance should be expected especially on higher mile examples…the engine usually is not the problem…it’s rather the electrical convenience of all the goodies. Rubber, plastic, suspension … buy the best quality batteries. Old cars…stuff brake .. GOT TO LOVE THE TOURQ AND SMOOTHNESS!
I had a 1999 850 before that drains the battery as well, had trouble with the electronic windows and interior lights. The culprit for all those issues was the computer module ll which was an easy fix. After repairing the module, it never had any battery draining issues, interior lights and electronic windows issues anymore and was trouble free that I used it for daily drive. It was a reliable car, very comfortable and beautiful.
We have two 850's in the stable and have experienced two of your issues. For the Seat, your issue is most likely a stretched cable that is no longer engaging. The symptom is commonly known as a "twisted seat" as there is one motor in the front that drives two cables and when one or both begin to fail the seats tend to twist. The fix is simple, and I would look for a new set of cables from a member of the community called "The Seat Guru" (no affiliation just a fan of his products) which are simple to install. The battery drain in these cars is most likely due to a failing capacitor in the general module. This fix requires the use of a soldering iron and may be something left to a pro. There are a few repair guides out there so just do a quick google search. Fixing your existing GM will save you the hassle of getting a new replacement programmed to match your car. Best of luck
the E31 was one of my dream car and still is. most of the 90's BMW has electronic issues which you will have to rely on forums and BMW communities to figure out the problem, but almost everything is fixable. at the end of the day, it is one of the best looking GT coupes ever made.
Well, typical for BWM workshops is to repair nothing but to replace any possible and impossible part for at least €400.00 each. We had that for months until we sued - and won.
I love my 1991 850i. It's true there are little mechanical things that bug me and it's waaay slower than my Corvette, but it's just a completely different experience. It feels good. It looks good. And I'm going to find a way to hack that car phone back to life!
@@adrianespinoza1561 Excellent taste. I almost got myself an 850 but I was already happily married with an 82 Lancia Gamma Coupé and a 78 Montreal and thank God my common sense prevailed over my heart. Needless to say, my wallet was thankful for that decision. I gifted my foster son an 88 325 Convertible when he got 18, though. A win-win move - I prevented him from buying a suicidal little turbo and I got myself a lovely open car for that occasional sunny ride.
I love these cars. I bought one a couple years ago. And yes it has problems but I love it! Definitely not a daily driver. Sure they cost some money to keep running but they are beautiful and nobody in your town has one and that's cool, not to mention it's by far the most gorgeous BMW ever made!
I've had an 840 for 7 years and 80,000 miles, mainly long distance transcontinental drives. These are complex cars but as long as you look after them they are reliable. There are excellent support websites in the USA, UK and Germany. Once you know how to fix things , they don't cost much. EG the last thing to fail on mine was the heating controller. A new one is mega bucks but thanks to online help it just needed 4 transistors soldering in the circuit board for less than 10 pounds / dollars / euros. They all drain current as the alarm runs all the time. In Europe we are not allowed guns so we need car alarms :o) , so in Europe the advice is keep it on a trickle charge. In the USA you can add a battery disconnect. If the battery is low you will have problems like limp mode... keep them charged up. I've never had a problem with engine electrics. The only time it failed to start was a blown fuse for the fuel pump. My only problems have been cooling system as it is made of plastic which becomes brittler with age.
Edward Cullen the cars are overly complicated even to support riding on the autobahn. Take that car to the USA, and it is just utter over engineering. Heck, a v8 auto from the '90's is overengineered. I should know, because I own one. It's an American Cadillac, and although there is nothing wrong with it, the poor Northstar doesn't get opened up, and exercised enough, and as such, it would develop sticky rings, and gummed up valves. The solution is just to take it out every few months, and ride it hard like I stole it. All we need in the USA is a simple computer controlled 8 valve 4cyl sfi engine.
@@gogogomes7025 Of course if its Lucas Electronics the Brits may snatch it back from the Germans. They are made common use of the Postive Grounding System...
You know what other car had that insane luxury space age design? The 1987 FWD corolla hatchback. Install a kill switch for the battery, and ignore all the other problems, oh and just pull the seat apart enough that you can crank the height down to a driveable location. That car has timeless lines!
Install a Battery Kill Switch. My dad had the same Problem on his Peugeot 205 Gti, we installed one, and now you just have to flick a switch before you go out and drive. And that's way better than having to jump the car every time you want to start it ;)
I own a 1991 850, my dad owned it before as a project and just didnt have time to keep working on it. Long story short, iv learned a lot about this car trying to bring it back to drivable state in the last year of ownership. I can tell you that a lot of the problems are E31 specific. Iv spent hours on forums, talking to other E31 owners, online research and found a few E31 specific groups on facebook and some of the members are long time E31 people who know the car like the back of their hand. Its fixable, trust me. Just need patience, and a wiring diagram. lol
also Erasers for the electric connections, as Brass Erodes, you cant see it but it does, and gets like a slick on it, had it happen on of all things the connections to my computers old router, just rubbed it down and it gave a noticeable difference in the quality of my connection. and if it works on that, god only knows what it would do with a BMW like that, just make sure its unplugged first! lol
The newer ones come with a fire extinguisher... Hey Hoovie, our 7 series AC would not command on from the DME because the auxiliary fan in front of the radiator was dead. Changed that out and voila AC again. Also the noisy AC compressor could have been simply overcharged and getting slugs of liquid refrigerant and causing a banging noise from the compressor vanes.
One other way to see whats drawing is to remove each fuse one at a time til you find what's drawing down the batteries, use a test meter attached to the battery, when it reads 0 you found your draw...
I feel your pain - literally. I bought a three year old 1991in 1994 and drove it 20,000 miles over the next few years. Everytime I took it to the dealer it was a $1000; didn't matter what the problem was. Water pump died?..might as well replace both of them was a common bit of advice. Sold the car and regretted it, so found an identical version years later in the 1994 840ci - the 8 cylinder version. The cars behave about the same, the V12 however has linear acceleration that feels like their is no limit to how fast it will go. The 840ci gets twice the mpg of the 12cyl and has a much throatier exhaust. Repair bills are still substantial however. Just completed a valley pan gasket replace, new radiator, new balancer and replaced any plastic fittings and hoses on the back of the engine that just deteriorated from age. The bill was about $7000, a lot for a car worth $15,000 on a really good day. Yet - I have never driven any car I enjoy as much. Just looking at it is a thrill, but this is a labor of love and the occasional deep pocket. These are great driving cars but if you're in the market buy the best one you can find...it's way cheaper.
During the intro, if you blur your eyes just right the rear of the car seems to have an awesome spoiler provided by the rear panel of the Jeep c pillars. Anyone else see it?
You're never suppose to jump BMW's from the trunk, they all have jumping points in the engine bay. Probably ok on one this old, but still not a good idea. I do not buy the 'car is unfixable' line for one second. Take your car to a highly recommended specialist, not someone who calls themselves a 'wizard'. Every BMW is fixable unless the body/frame is literally falling apart. Pretty much every other part is replaceable, name something that is not.. The electrical problems you're describing (new battery going dead in 1 week) can only really be caused by a parasitic draw (which is very common especially on vehicles from this period which often had aftermarket alarms installed), or a shit alternator. Missing relays could also be the cause of 'electrical gremlins' or things not working properly, again something you should have a specialist look at. Depending on if you're willing to put the money into the car, and take it to the right people, every single thing you described is 100% fixable. The other issue you mentioned about the A/C also sounds like you got 100% ripped off. He basically just threw every part at it (stealership tactics) and on top of that fucked something up so badly it didn't even work after. Wiring diagrams for these cars are available, he just wasn't able to find it. You're literally describing a bad mechanic, not a bad car. Everything described is as if you took your cars to any general mechanic who works on whatever comes through their doors. Take it to someone who only looks at BMW, and knows these cars inside and out
Bmw Fanboy comment. Yes any problem can be fixed but a bunch of minor issues eventually add up to be the price of the car or better when your purchasing on the used market. I like BMW they're Nice cars but they're built for the design not the wallet or for a easy cheap repair. Not the fault of the brand just what you get when you want everything in a small form and to be powerful both mechanically and electrically. He also hasn't taken it to "the car wizard" yet, Listen and he says he brung it to another mechanic. Not every car is worth the repair, Thats why you see these cars along side mitsubishis and hondas on the used market for just a few grand in nice shape. You can take care of them all you want but somethings going to go wrong either way, just how luxury cars work. I know people who bought them brand new and upkept it yet still had major $1000+ bills under a year in and less then 100k miles. Again, Not saying its a bad car, Just not everything is worth the cost to fix. if you dont believe me look on craigslist you find them either under 100k miles because theyre trying to recoup some money or just over 100k with some problems and beyond that is a mechanic special. Even mustangs and corvettes can be found running strong at 200k but to see a bmw that isnt trashed by then is someone who really loved the car and didnt mind the wallet being empty to keep it living.
BMW Australia and its dealers have a unique procedure to repair of any issue. Just exchange used parts for new until the issue or issues are resolved. Than present the customer with an invoice that exceeds the cars value by 200 % !!! .BMW is another manufacturer of complete irrelevance.
You are correct. The problem is, there were very few of these sold(compared to other series), so only a limited number of BMW certified mechanics "studied" the 8 series maintenance. However, this car is a piece of art and so these are the three things that Hoovies should do: -Fix it -Detail it -Preserve it
I love how pretentious he is, and self deprecating at the same time. And he always speaks of the trade offs he is willing to make. The car is a "gentleman's lounge" while still being a "complete dumpster fire". Having seen my parents 1980's 533 BMW electrical system fall apart after 5 years, I resolved the cars were just not worth the money, to buy new. As usual however, you have to pay to play. Recently I have been missing my 1971 Olds Cutlass, with its long wheelbase, effortless power, and comfortable highway ride. Along with its under the steering column A/C vent, which Hoovie would probably love. Not so much the gentleman's lounge that car, but just a great relaxing ride on the highway.
A high performance EV conversion of one of these is the perfect update to it. Damien macguire, the most boring interesting man on TH-cam, recently did this with his panzer project, using a Tesla power unit for that sweet torque.
Welcome to the world of classic car ownership. Your 850i looks wonderful. Hopefully you will persevere and ultimately get all the issues solved. The major problem with repair and servicing of cars of this age and complexity is finding a knowledgeable specialist. Most technicians will either have never been trained or worked on vehicles of this age ir haven't worked on them in decades. Finding a specialist is key, my suggestion would be internet owners forums are a source of information.
Alexpmgr8 K3 Try using a pair of deep cycle batteries a few AH above the standard value until you figure out where the drain is comming from. That way you wont spend a fortune on pairs of fragile lead acid batteries. The drain can also be halted by a couple of total power shut off switches both bolted directly to the batteries, this will also aid normal start up.
Love My old e34 525 Always starts after 340000km Only setback is the rust, always a struggle on the vinter, holding it nice from the salt on the roads...
Yep - people don't understand that cars designed for comfort are just better than "sporty" cars (what "sports" are people expecting to do in a diesel Audi with 20" wheels?). People are idiots.
If I remember correctly you have to go into the hvac pcm and clear a low refrigerant code to get the a/c working after the pressure sensor senses low pressure. I may be mistaken though but worth a full system scan clear for sure.
It’s more like the sealed battery in alarm siren, or bad light module. Could be blower resistor toward rear passenger side. Do a draw test and see what system drawing current. I had to dump 4K into my 7 series to get it close to 100 percent. Did the work myself had to pretty much replace all gasket and plastic parts when rebuilding motor and transmission. One of the nicest feel ride once issues are corrected. I just wish BMW used better plastics that didn’t deteriorate as bad.
There is a box in the driver side door floorboard that probably got wet. Its in the in bottom fender wheel. Just pull the carpet back. If you sitting down it should be right about where your knees are. If it go wet, which they easily do, it could have got damaged and whats draining the battery. Just open the box when you take it out and you will see if its rusted or has water damage. Some idiots try to clean it but it never comes back. It controls everything though. windows, door locks, etc. Sends power everywhere to everything even when no key is in the ignition. You can unplug the box and see if you batteries stay alive. Good Luck. I have had two of the cars and rebuilt one of them from the ground up bolt for bolt.
Dank Memes Bruh on my second 850i I had to replace the box three times. Was bad on purchase, Second because I went through to high of water and the third time because I left the window down when it was raining . Expensive box to keep buying, arrghhh the memories but I loved that damn car.
greg h he will spend a lot more than that if he brings it to people that don’t know that car. I can tell if a DK motor is going bad just by how the engine revs. I actually use to have the wiring schematics for the car but gave them away to last guy that I sold my last 850 to. I know that car as well as the engineers that built it. I have had about 35 cars already in life and the 850 is by far my favorite . I drive a AMG CLS Mercedes today and it wouldn’t be a second thought to toss it and have a 850 again. I hope he does read this. I would be more than happy to help offer free help if he needs . Second he bought this car, the became my favorite automotive TH-cam channel.
vmystikilv - I'm the third owner of a 1991, 850i with 67k miles on it, previously owned by Kirk Douglas. I absolutely love my 8 and plan on passing down to my son. Recently I've run into some mechanical problems with my 8. I've researched the issues and found that the problems are typical problems that come with owning an 8 series. I consider myself a novice car mechanic who can follow instructions but can't dive right into diagnosing and fixing a car problem. I refuse to let a mechanic try and diagnose or recommend any type of repair issues for fear of being ripped off or being taken advantage of, besides repairing it myself would add to the love I have for this car. I was hoping I could explain to you what the problems were with my 8 so you could recommend some tips on how I could try and repair it.
As 850bimmer alludes to below, BEFORE the exterior temperature drops to 45F have the General Module under the steering wheel re-conditioned. In colder temps the electronics will go crazy: Your wipers, lights, sunroof won't work, but you won't care because the windows won't drop when you lift the door handle and you won't be able to get in. The courtesy lights will flash on and off like a disco and the trunk will be locking and unlocking itself. If you do get in after this happens ( leave the drivers window down an inch ) the problems will disappear in about 20 minutes after heating up. The Thrill of ownership!
Battery drain may be a diode in the alternator that has failed. I notice with the AC replacement the mechanic converted to r134a with the cap showing in the video, when you do this you also need to change the expansion valve and pressure switch that is comparable with r134a to make the system work. I always found no car is really bad and you can usually find a problem leads back to a person that wasn't careful :-) Dave
My brother runs his own shop with one employee, and works on 750's and 850's sometimes, but he will not give up on them until he fixes them, he learned by working on them for 25 years, plus I bought a 1992 750il in 1997 as a personal car. I have learned that being a daily driver is really best, letting them sit can be worse than running the piss out of them everyday, Vacuum leaks mainly from oil gaskets, oil pan the worst because it is horrible to fix, it has two pan gaskets, fowling plugs during cold starts, ignitors for plugs, getting the very back plugs out, and weird electrical faults on the transmission, ect.... The AC in the 1992 is original and functions after a recharge annually, the trans works good until defaulted, heavy but handles well on BMW car club drives where people are amazed, it is parked now and we know it will be hard as hell to start and we will remember what needs to be fixed the moment we get it out. Having 750 and 850 experience is vital to analyzing it's problems right and fixing them, and my brother is usually friends of many of his V12 customers so they are flexible on dealing with the worst first and finishing the rest, because there is always something to do. :)
Cars like this have so many electronic modules that develope cold solder joints in side, especially bad solder joints where the harness connectors attach to the pc boards. Go through every module and check/resolder all the connectors..and things will work like magic!
Owned several BMW 12 cylinder models over the years. This engine design is reliable and knowned to be near bulletproof. Any thing can be repaired with knowledgeable technicians. Consider finding a new technician perhaps in another city. It is true that under the hood work can be expensive primarily because it is necessary to remove numerous items for adequate access. I'm driving a 20 year old BMW 12 cyl. now and it takes a few thousand dollars in maintenance ever now and again. You can find a decent 750il for less than $5000 in many markets and an 850i for not so much more. A lot of torque for the money. Cars from this period were the most attractive BMWS to my eye.
My uncle has a blue BMW 850i, I think for about 15 years now. I still recognize the beeps when you get into the car, the interior, and the sound when you start the engine (think his exhausts are changed a bit, his is somewhat louder). Indeed, the typical maintenance problem you describe. No one has the skills to work with these cars, they are enormous, and a V12 with dual 6 cyilinder equipment!!!?.... Holy hell... Get ready for grabbing into the pocket for parts and labor xD Edit: He doesn't have the battery drain issue. But maybe he solved that with a massive relay somewhere (or again; TWO of those hahahahahaha). Fun story he had his BMW taken care of by a couple of different people. And basically all were unable to do propper maintenance on it. He then found a guy through a forum/community group. The guy made a checklist and started to do the things with top priority. The car would be gone for 3 weeks. That lasted.. it went to 5 weeks... 7 weeks... After 8 weeks he contacted him, and finally got his wife on the phone. He had passed away and there were 6 cars in his garage they couldn't find the owners off xD
there is a module to regulate between the two batteries one of the batteries is deep cycle and not for starting the car.because most car sales guys are dumber than a box of hammers they head straight to the battery to jump start car instead of positive post in the engine bay.the resulting spike will damage module and maybe others further up the chain like lighting or heating module causing strange faults and current draws.pinched wiring looms can have same effect.
The 850/840 and the Porsche 928 are two of the most beautiful cars designed. And your very last comment "it's made for me, umm humm" was too hilarious 😂
motors are very reliable. if you get the voltage issues fixed, the car will be really enjoyable for you to drive. i daily my 750 with the M73 and it's been great to me. pretty fun to work on, rebuilt the top half for preventative maintenance and did all the ignition parts. only time it left me stranded was when the alternator failed.
I'm only 3 minutes in but... is your mic actually working today?! Well done! Well look at that, the mic worked the whole way through the episode. +1 internet point for you.
I had the mystery battery drain in my 1991 Honda Accord. I measured the drain current with an ammeter and the verdict was bad. It's too high for standby current (and I pulled all the relevant fuses for the radio and ECU anyway), but way too low for a proper short. The relatively new battery would go flat in about 5-6 days if car was not driven. In the end I decided the car was too old to spend time ripping it all apart in search of likely corroded wires somewhere, as I knew the likely source of the problem was constant leaks and moisture over the years from bad rubber moldings (for as long as I remember the car would have windows frosted or misty on the inside on the cold days and fogged on the inside on the hot days). Sold it after I finished college as at that particular time I was working from home and was hardly ever using a car, so that wasn't much of an issue. Since starting a new 8-5 job however I drive one of those beige Korean cars and really miss my compact flickable Honda coupe. They don't make 'em like that anymore.
I’m sure it’s gone by now but I would love to sort this car mechanically out if I could afford it, I’m nerding out on this car it’s so beautiful. Alas hoovie wouldn’t have kept this hooptie so long so now I will cry myself to sleep watching Car Issues on demand. Great video? Great car.
Battery draw issue is GM module capacitors require replacing, common problem with 20+yr old caps, $10 job. NEVER jump start these cars or try to run with low battery levels, this will give you more electronic issues. ALL the BMW factory electrical/mechanical manuals are available for free on line. Register the car at 8coupedotcom and read like crazy at bimmerforumsdotcom, 8erdotaug etc.
Hoovie, been a regular since the very beginning of your channel. Took a break and recently came back. Great to see your work being appreciated as much today! Onto my point: How about a CLS W219 review? I own an absolutely fully-decked out CLS500 because it was my teenage wetdream, and I love it to death. I don't believe it's as popular in the US, so your viewers would get a kick out of it. It's a stunningly beautiful car with a ton of forward-facing gadgetry inside of it at the time of prototyping, and it single-handedly started a new car trend among makers. I love it to death, and I'm sure you will too!
Why in the world is the bottom button on your jacket buttoned? Not only do you never button the bottom button, but you buttoned the bottom button AND left the top open.
Well.... if it's any comfort, I just bought a 92 850IA with some minor issues that will cost me around $5000 to fix, on top of that, I'm repainting the whole car, that's another $2000, then I'm gonna do a full job on the interior and leather, that's another $1500, 4 new summer tires, that's another $400.....oh, and, 2 new batteries, $300. Grand total: $9200. I bought the car for $6000, grand total: $15200...... yaaaaaaaaaay.........
I'm going for Michelin Sport 4S, buying from a friend who works at a tire shop, the actual price is approx the double, incl mount and balance. The PS4 you're mentioning are a bit to hard for a comfort ride, too much noice, but a hell of a tire!
I hear you Erwin, but I'm beginning to question my purchase of this car due to all the costs..... is it really wort it in case I want to sell it someday? Will I get my money back? Will these models be worth more in 2 years when the new gen 850 arrives? Who knows?!
There are three body control units under driver's kick panel they are called KGM. Basically two are slaves and one master. I had to fix an 840i and an 850i with similar current draws and / or weird electrical act ups. I recommend checking them.
Hey Hoovie, here's how to get your car fixed, surefire. 1. E-mail German BMW dealership (say Wilhelmshaven since its a port on the NW coast) of your choice informing them you will be sending them your BMW over in a container and that they should send somebody to pick it up and drive it to the dealership. 2. Ask them to completely repair your car listing in detail what's wrong with it, 3. Ask them to ship it back to you same way they got it.
This video encapsulates the BMW brand perfectly. Fun to drive, great comfort and performance. On the other hand, the electronics are garbage long term and they are (as Scotty Kilmer calls them) bottomless money pit machines.
Battery drain is one of the simplest things you can solve. So, here it is. 1. Get a voltmeter, connect it to the batteries. with everything turned off and the key out of the ignition it should read very close to zero. On your car it should be quite above that. 2. Remove fuse by fuse until the reading goes down. 3. check what is that fuse powering in the owner manual or online and replace/repair the part 4. If that doesn't work it must be some aftermarket stuff connected to that fuse and you will have to check/disconnect wire by wire until you find the culprit. 5. good luck
I have a BMW Z3, and when I bought it, if it stood for about 3-4 days the battery was flat, I thought it was the clock and other electronic things on the car that was draining the battery, until I noticed that the small fuse size boot light was always on, even when the boot was closed, hence the flat battery, Check on your BMW 850s and see if the boot light is going out or stopping on all the time.
My father was the original owner of this car. I have so many memories driving with him in this 850. I was the 2nd owner. Thank you for putting in the effort to bring her back up to snuff. So cool to see this video!
As an 850 owner of 12 years, the drain problem solution is literally a 30 second google search away, and would cost you 10usd in capacitors, 15 minutes to remove unit from the car and 30 minutes with a soldering iron.
This car CAN be fixed, but not at a shop as they are useless on old cars like these. Get on the forums where the real knowledge is, there are people on the forums who have owned these cars for 15+ years, and there is NOT A THING that the community don't know how to fix.
And if you can't work on it yourself, alt least you know what to tell you mechanic to fix.
this guy is on it..... the caps swell up on the PCBs ... replace all Capacitors not just the ones that look or test bad.
shops dont do componenet level repair anymore...got to DIY
Hehe, I don't thing a euro car is more prone to gremlins than any other 25+ year old car, regardless of origin.
It's a well known issue with the GM2 and RM5 modules on these cars.
The caps dry out and change their value just enough for the car not going to "sleep" after 16 minutes. You are left with a 4-500mA drain instead of a 50-60mA. leading to flat batteries in 7-10 days, rather than 4-5 months.
In very rare cases there has been a drain from the one of the door locks too.
30 second google search an a DIY pops up.
Owning a car like this means you are more lightly to get help in the community than in a shop, heck, most BMW techs have never seen any of these cars.
the big question is will he read this and fix the car
WPWBigCheese probably not. To busy making videos, doing his day job and searching for useless techs ro waste more money on scans and quasi-diagnosis that don't lead anywhere. Some people think that because AutoZone does free scans then so do techs.
1) PLEASE don’t ever jump this car from the batteries again. Sure fire way to cause electrical damage. only jump it from the terminals under the hood.
2) your electrical draw issue can likely be resolved for around $100. It is the capacitors in the general module. They need to be replaced.
3) Did the mechanic test the seat motor to ensure it’s actually the motor itself? Often times the cables get out of whack on the seats and prevent them from moving properly even though the seat motors (which are very robust) are actually working. There are replacement cables available for under $200.
We have to remember these are 25 year old cars that very few people know how to work on now because of their rarity. However, there is a huge group of enthusiasts that k ow how to fix them and are willing to help fellow owners.

Hey Hoovie, did you take this man's advice? If not, see if he is right. If you did you should at the very least acknowledge his post!!
Much disappointed in Hoovie.. I get that he doesn't have time to reply to 2.3K posts. But this is the highest rating, smartest, and the most helpful.
I cringed as soon as he started walking to the back to jump it and said out loud to my wife, "That's why he has electrical issues."
Please explain why jumping from the batteries is a bad thing?
The engine is 2 engines in one. However the m70 and m73 are both considered very bullet proof … added complexity requires replacing some items down the road. These are like an airplane that periodic maintenance should be expected especially on higher mile examples…the engine usually is not the problem…it’s rather the electrical convenience of all the goodies. Rubber, plastic, suspension … buy the best quality batteries.
Old cars…stuff brake .. GOT TO LOVE THE TOURQ AND SMOOTHNESS!
I had a 1999 850 before that drains the battery as well, had trouble with the electronic windows and interior lights. The culprit for all those issues was the computer module ll which was an easy fix. After repairing the module, it never had any battery draining issues, interior lights and electronic windows issues anymore and was trouble free that I used it for daily drive. It was a reliable car, very comfortable and beautiful.
We have two 850's in the stable and have experienced two of your issues.
For the Seat, your issue is most likely a stretched cable that is no longer engaging. The symptom is commonly known as a "twisted seat" as there is one motor in the front that drives two cables and when one or both begin to fail the seats tend to twist. The fix is simple, and I would look for a new set of cables from a member of the community called "The Seat Guru" (no affiliation just a fan of his products) which are simple to install.
The battery drain in these cars is most likely due to a failing capacitor in the general module. This fix requires the use of a soldering iron and may be something left to a pro. There are a few repair guides out there so just do a quick google search. Fixing your existing GM will save you the hassle of getting a new replacement programmed to match your car.
Best of luck
David Friesner neither of those problems sound insurmountable. (EE here;)
Hoovie is single-handedly paying for his mechanic's kids' university degrees.
Bingo
the E31 was one of my dream car and still is. most of the 90's BMW has electronic issues which you will have to rely on forums and BMW communities to figure out the problem, but almost everything is fixable. at the end of the day, it is one of the best looking GT coupes ever made.
Shoulda called M539 Restorations. He lives for these!
Simple job to install an amp meter to monitor the draw, then disconnect each component till the draw is found.
"Unfixable" translates in mechanic-speak to "unprofitable".
what do you mean?
Yeah, he even said that at 8:00
All his cars he eventually gets a return on. Fixing this = no bueno
Well, typical for BWM workshops is to repair nothing but to replace any possible and impossible part for at least €400.00 each. We had that for months until we sued - and won.
benjamin israel
it means that mechanics say its unfixable because its too much work to do for the pay and time needed to put into it
The seat headrests look like they’re floating
mupet00000 It is. Its BMW technology invented in 1987 and never replicated by anyone. Its called suspended seat technology

I love my 1991 850i. It's true there are little mechanical things that bug me and it's waaay slower than my Corvette, but it's just a completely different experience. It feels good. It looks good. And I'm going to find a way to hack that car phone back to life!

@@adrianespinoza1561 Excellent taste. I almost got myself an 850 but I was already happily married with an 82 Lancia Gamma Coupé and a 78 Montreal and thank God my common sense prevailed over my heart. Needless to say, my wallet was thankful for that decision. I gifted my foster son an 88 325 Convertible when he got 18, though. A win-win move - I prevented him from buying a suicidal little turbo and I got myself a lovely open car for that occasional sunny ride.
I love these cars. I bought one a couple years ago. And yes it has problems but I love it! Definitely not a daily driver. Sure they cost some money to keep running but they are beautiful and nobody in your town has one and that's cool, not to mention it's by far the most gorgeous BMW ever made!

Your dog is like your car.. first it looks at you in complete astonishment and then it totally ignore you
your dog is such a good boy
I've had an 840 for 7 years and 80,000 miles, mainly long distance transcontinental drives. These are complex cars but as long as you look after them they are reliable. There are excellent support websites in the USA, UK and Germany. Once you know how to fix things , they don't cost much. EG the last thing to fail on mine was the heating controller. A new one is mega bucks but thanks to online help it just needed 4 transistors soldering in the circuit board for less than 10 pounds / dollars / euros. They all drain current as the alarm runs all the time. In Europe we are not allowed guns so we need car alarms :o) , so in Europe the advice is keep it on a trickle charge. In the USA you can add a battery disconnect. If the battery is low you will have problems like limp mode... keep them charged up. I've never had a problem with engine electrics. The only time it failed to start was a blown fuse for the fuel pump. My only problems have been cooling system as it is made of plastic which becomes brittler with age.

Gotta love that German over-engineering. Why use a simple switch when two microprocessors and 10,000 lines of code works best for the glovebox light.
Edward Cullen the cars are overly complicated even to support riding on the autobahn. Take that car to the USA, and it is just utter over engineering. Heck, a v8 auto from the '90's is overengineered. I should know, because I own one. It's an American Cadillac, and although there is nothing wrong with it, the poor Northstar doesn't get opened up, and exercised enough, and as such, it would develop sticky rings, and gummed up valves. The solution is just to take it out every few months, and ride it hard like I stole it. All we need in the USA is a simple computer controlled 8 valve 4cyl sfi engine.
Any car can become a money pit. Most American cars from the 70s through to the 90s, for example.

You know what other car had that insane luxury space age design? The 1987 FWD corolla hatchback.
Install a kill switch for the battery, and ignore all the other problems, oh and just pull the seat apart enough that you can crank the height down to a driveable location. That car has timeless lines!
I cant believe I didnt notice that!
*because there is no b pillor (i don't know if i wrote that right)
Install a Battery Kill Switch. My dad had the same Problem on his Peugeot 205 Gti, we installed one, and now you just have to flick a switch before you go out and drive. And that's way better than having to jump the car every time you want to start it ;)
install a toggle switch to disconnect the battery after every drive, low tech fix?

@@NiggaGang69 I thought you died?
I own a 1991 850, my dad owned it before as a project and just didnt have time to keep working on it. Long story short, iv learned a lot about this car trying to bring it back to drivable state in the last year of ownership. I can tell you that a lot of the problems are E31 specific. Iv spent hours on forums, talking to other E31 owners, online research and found a few E31 specific groups on facebook and some of the members are long time E31 people who know the car like the back of their hand. Its fixable, trust me. Just need patience, and a wiring diagram. lol
check the grounds for the batteries and chassis grounds. I had similar issues, nothing a scuff pad and time can fix. hope this helps.
also Erasers for the electric connections, as Brass Erodes, you cant see it but it does, and gets like a slick on it, had it happen on of all things the connections to my computers old router, just rubbed it down and it gave a noticeable difference in the quality of my connection.
and if it works on that, god only knows what it would do with a BMW like that, just make sure its unplugged first! lol
The BMW Gentleman's Briefcase had me on the floor. 😁
Love Dino too!
The newer ones come with a fire extinguisher... Hey Hoovie, our 7 series AC would not command on from the DME because the auxiliary fan in front of the radiator was dead. Changed that out and voila AC again. Also the noisy AC compressor could have been simply overcharged and getting slugs of liquid refrigerant and causing a banging noise from the compressor vanes.
One other way to see whats drawing is to remove each fuse one at a time til you find what's drawing down the batteries, use a test meter attached to the battery, when it reads 0 you found your draw...
I feel your pain - literally. I bought a three year old 1991in 1994 and drove it 20,000 miles over the next few years. Everytime I took it to the dealer it was a $1000; didn't matter what the problem was. Water pump died?..might as well replace both of them was a common bit of advice. Sold the car and regretted it, so found an identical version years later in the 1994 840ci - the 8 cylinder version.
The cars behave about the same, the V12 however has linear acceleration that feels like their is no limit to how fast it will go. The 840ci gets twice the mpg of the 12cyl and has a much throatier exhaust. Repair bills are still substantial however. Just completed a valley pan gasket replace, new radiator, new balancer and replaced any plastic fittings and hoses on the back of the engine that just deteriorated from age. The bill was about $7000, a lot for a car worth $15,000 on a really good day. Yet - I have never driven any car I enjoy as much. Just looking at it is a thrill, but this is a labor of love and the occasional deep pocket. These are great driving cars but if you're in the market buy the best one you can find...it's way cheaper.
During the intro, if you blur your eyes just right the rear of the car seems to have an awesome spoiler provided by the rear panel of the Jeep c pillars. Anyone else see it?
Yea, I see it....Wish I hadn't had the 2nd look now... LOL
Try disconnecting the alarm siren, it has rechargeable batteries in it and draws down current.

You're never suppose to jump BMW's from the trunk, they all have jumping points in the engine bay. Probably ok on one this old, but still not a good idea. I do not buy the 'car is unfixable' line for one second. Take your car to a highly recommended specialist, not someone who calls themselves a 'wizard'. Every BMW is fixable unless the body/frame is literally falling apart. Pretty much every other part is replaceable, name something that is not.. The electrical problems you're describing (new battery going dead in 1 week) can only really be caused by a parasitic draw (which is very common especially on vehicles from this period which often had aftermarket alarms installed), or a shit alternator. Missing relays could also be the cause of 'electrical gremlins' or things not working properly, again something you should have a specialist look at. Depending on if you're willing to put the money into the car, and take it to the right people, every single thing you described is 100% fixable. The other issue you mentioned about the A/C also sounds like you got 100% ripped off. He basically just threw every part at it (stealership tactics) and on top of that fucked something up so badly it didn't even work after. Wiring diagrams for these cars are available, he just wasn't able to find it. You're literally describing a bad mechanic, not a bad car. Everything described is as if you took your cars to any general mechanic who works on whatever comes through their doors. Take it to someone who only looks at BMW, and knows these cars inside and out
Bmw Fanboy comment. Yes any problem can be fixed but a bunch of minor issues eventually add up to be the price of the car or better when your purchasing on the used market. I like BMW they're Nice cars but they're built for the design not the wallet or for a easy cheap repair. Not the fault of the brand just what you get when you want everything in a small form and to be powerful both mechanically and electrically. He also hasn't taken it to "the car wizard" yet, Listen and he says he brung it to another mechanic. Not every car is worth the repair, Thats why you see these cars along side mitsubishis and hondas on the used market for just a few grand in nice shape. You can take care of them all you want but somethings going to go wrong either way, just how luxury cars work. I know people who bought them brand new and upkept it yet still had major $1000+ bills under a year in and less then 100k miles. Again, Not saying its a bad car, Just not everything is worth the cost to fix. if you dont believe me look on craigslist you find them either under 100k miles because theyre trying to recoup some money or just over 100k with some problems and beyond that is a mechanic special. Even mustangs and corvettes can be found running strong at 200k but to see a bmw that isnt trashed by then is someone who really loved the car and didnt mind the wallet being empty to keep it living.
Anything can be fixed, except for the hole in your wallet...
BMW Australia and its dealers have a unique procedure to repair of any issue. Just exchange used parts for new until the issue or issues are resolved. Than present the customer with an invoice that exceeds the cars value by 200 % !!! .BMW is another manufacturer of complete irrelevance.

You are correct. The problem is, there were very few of these sold(compared to other series), so only a limited number of BMW certified mechanics "studied" the 8 series maintenance.
However, this car is a piece of art and so these are the three things that Hoovies should do:
-Fix it
-Detail it
-Preserve it
Dude that's an awsome lovable dog!!!
I love how pretentious he is, and self deprecating at the same time. And he always speaks of the trade offs he is willing to make. The car is a "gentleman's lounge" while still being a "complete dumpster fire". Having seen my parents 1980's 533 BMW electrical system fall apart after 5 years, I resolved the cars were just not worth the money, to buy new. As usual however, you have to pay to play. Recently I have been missing my 1971 Olds Cutlass, with its long wheelbase, effortless power, and comfortable highway ride. Along with its under the steering column A/C vent, which Hoovie would probably love. Not so much the gentleman's lounge that car, but just a great relaxing ride on the highway.
Temporarily...Add a switch to disconnect the battery, when not in use...Turn the switch on, and then start the motor when you wish to drive it.
That bummer looks great for the age. Wouldn’t think it was nearly 30 years old.
A high performance EV conversion of one of these is the perfect update to it.
Damien macguire, the most boring interesting man on TH-cam, recently did this with his panzer project, using a Tesla power unit for that sweet torque.
Welcome to the world of classic car ownership. Your 850i looks wonderful.
Hopefully you will persevere and ultimately get all the issues solved.
The major problem with repair and servicing of cars of this age and complexity is finding a knowledgeable specialist.
Most technicians will either have never been trained or worked on vehicles of this age ir haven't worked on them in decades. Finding a specialist is key, my suggestion would be internet owners forums are a source of information.

Try using a pair of deep cycle batteries a few AH above the standard value until you figure out where the drain is comming from. That way you wont spend a fortune on pairs of fragile lead acid batteries. The drain can also be halted by a couple of total power shut off switches both bolted directly to the batteries, this will also aid normal start up.
Love My old e34 525 Always starts after 340000km
Only setback is the rust, always a struggle on the vinter, holding it nice from the salt on the roads...
Yep - people don't understand that cars designed for comfort are just better than "sporty" cars (what "sports" are people expecting to do in a diesel Audi with 20" wheels?).
People are idiots.
Battery disconnect switch... FTW!
If I remember correctly you have to go into the hvac pcm and clear a low refrigerant code to get the a/c working after the pressure sensor senses low pressure. I may be mistaken though but worth a full system scan clear for sure.
It’s more like the sealed battery in alarm siren, or bad light module. Could be blower resistor toward rear passenger side. Do a draw test and see what system drawing current. I had to dump 4K into my 7 series to get it close to 100 percent. Did the work myself had to pretty much replace all gasket and plastic parts when rebuilding motor and transmission. One of the nicest feel ride once issues are corrected. I just wish BMW used better plastics that didn’t deteriorate as bad.
Try replacing the ignition switch to fix the battery draw.
I would buy it in a heartbeat, it’s a Classic Work of art, these will only Appreciate.
There is a box in the driver side door floorboard that probably got wet. Its in the in bottom fender wheel. Just pull the carpet back. If you sitting down it should be right about where your knees are. If it go wet, which they easily do, it could have got damaged and whats draining the battery. Just open the box when you take it out and you will see if its rusted or has water damage. Some idiots try to clean it but it never comes back. It controls everything though. windows, door locks, etc. Sends power everywhere to everything even when no key is in the ignition. You can unplug the box and see if you batteries stay alive. Good Luck. I have had two of the cars and rebuilt one of them from the ground up bolt for bolt.
Dank Memes Bruh on my second 850i I had to replace the box three times. Was bad on purchase, Second because I went through to high of water and the third time because I left the window down when it was raining . Expensive box to keep buying, arrghhh the memories but I loved that damn car.
you're probably right but i think he will probably never read this and spend 1000$ taking it to a car electrician "specialist"
greg h he will spend a lot more than that if he brings it to people that don’t know that car. I can tell if a DK motor is going bad just by how the engine revs. I actually use to have the wiring schematics for the car but gave them away to last guy that I sold my last 850 to. I know that car as well as the engineers that built it. I have had about 35 cars already in life and the 850 is by far my favorite . I drive a AMG CLS Mercedes today and it wouldn’t be a second thought to toss it and have a 850 again. I hope he does read this. I would be more than happy to help offer free help if he needs . Second he bought this car, the became my favorite automotive TH-cam channel.
vmystikilv - I'm the third owner of a 1991, 850i with 67k miles on it, previously owned by Kirk Douglas. I absolutely love my 8 and plan on passing down to my son. Recently I've run into some mechanical problems with my 8. I've researched the issues and found that the problems are typical problems that come with owning an 8 series. I consider myself a novice car mechanic who can follow instructions but can't dive right into diagnosing and fixing a car problem. I refuse to let a mechanic try and diagnose or recommend any type of repair issues for fear of being ripped off or being taken advantage of, besides repairing it myself would add to the love I have for this car. I was hoping I could explain to you what the problems were with my 8 so you could recommend some tips on how I could try and repair it.
@@gregh7457 Its another year..and no updates pinned. None of them do that. Like planned obsolescence video.
As 850bimmer alludes to below, BEFORE the exterior temperature drops to 45F have the General Module under the steering wheel re-conditioned. In colder temps the electronics will go crazy: Your wipers, lights, sunroof won't work, but you won't care because the windows won't drop when you lift the door handle and you won't be able to get in. The courtesy lights will flash on and off like a disco and the trunk will be locking and unlocking itself. If you do get in after this happens ( leave the drivers window down an inch ) the problems will disappear in about 20 minutes after heating up. The Thrill of ownership!

Battery drain may be a diode in the alternator that has failed. I notice with the AC replacement the mechanic converted to r134a with the cap showing in the video, when you do this you also need to change the expansion valve and pressure switch that is comparable with r134a to make the system work. I always found no car is really bad and you can usually find a problem leads back to a person that wasn't careful :-)

My brother runs his own shop with one employee, and works on 750's and 850's sometimes, but he will not give up on them until he fixes them, he learned by working on them for 25 years, plus I bought a 1992 750il in 1997 as a personal car. I have learned that being a daily driver is really best, letting them sit can be worse than running the piss out of them everyday, Vacuum leaks mainly from oil gaskets, oil pan the worst because it is horrible to fix, it has two pan gaskets, fowling plugs during cold starts, ignitors for plugs, getting the very back plugs out, and weird electrical faults on the transmission, ect.... The AC in the 1992 is original and functions after a recharge annually, the trans works good until defaulted, heavy but handles well on BMW car club drives where people are amazed, it is parked now and we know it will be hard as hell to start and we will remember what needs to be fixed the moment we get it out. Having 750 and 850 experience is vital to analyzing it's problems right and fixing them, and my brother is usually friends of many of his V12 customers so they are flexible on dealing with the worst first and finishing the rest, because there is always something to do. :)

Owned several BMW 12 cylinder models over the years. This engine design is reliable and knowned to be near bulletproof.
Any thing can be repaired with knowledgeable technicians. Consider finding a new technician perhaps in another city.
It is true that under the hood work can be expensive primarily because it is necessary to remove numerous items for adequate access.
I'm driving a 20 year old BMW 12 cyl. now and it takes a few thousand dollars in maintenance ever now and again. You can find a decent 750il for less than $5000 in many markets and an 850i for not so much more.

I have a 2003 BMW Z4, 3.0 M54 B30 ZHP. It has 175000 miles on it, 6 speed manual and I do love that car.
My uncle has a blue BMW 850i, I think for about 15 years now. I still recognize the beeps when you get into the car, the interior, and the sound when you start the engine (think his exhausts are changed a bit, his is somewhat louder). Indeed, the typical maintenance problem you describe. No one has the skills to work with these cars, they are enormous, and a V12 with dual 6 cyilinder equipment!!!?.... Holy hell... Get ready for grabbing into the pocket for parts and labor xD
Edit: He doesn't have the battery drain issue. But maybe he solved that with a massive relay somewhere (or again; TWO of those hahahahahaha).
Fun story he had his BMW taken care of by a couple of different people. And basically all were unable to do propper maintenance on it. He then found a guy through a forum/community group. The guy made a checklist and started to do the things with top priority. The car would be gone for 3 weeks. That lasted.. it went to 5 weeks... 7 weeks... After 8 weeks he contacted him, and finally got his wife on the phone. He had passed away and there were 6 cars in his garage they couldn't find the owners off xD
there is a module to regulate between the two batteries one of the batteries is deep cycle and not for starting the car.because most car sales guys are dumber than a box of hammers they head straight to the battery to jump start car instead of positive post in the engine bay.the resulting spike will damage module and maybe others further up the chain like lighting or heating module causing strange faults and current draws.pinched wiring looms can have same effect.
Dino seems like an awesome dog. A credit to his human =)

put in a battery kill switch
The 850/840 and the Porsche 928 are two of the most beautiful cars designed. And your very last comment "it's made for me, umm humm" was too hilarious 😂
motors are very reliable. if you get the voltage issues fixed, the car will be really enjoyable for you to drive. i daily my 750 with the M73 and it's been great to me. pretty fun to work on, rebuilt the top half for preventative maintenance and did all the ignition parts. only time it left me stranded was when the alternator failed.

Well look at that, the mic worked the whole way through the episode. +1 internet point for you.
I had the mystery battery drain in my 1991 Honda Accord. I measured the drain current with an ammeter and the verdict was bad. It's too high for standby current (and I pulled all the relevant fuses for the radio and ECU anyway), but way too low for a proper short. The relatively new battery would go flat in about 5-6 days if car was not driven. In the end I decided the car was too old to spend time ripping it all apart in search of likely corroded wires somewhere, as I knew the likely source of the problem was constant leaks and moisture over the years from bad rubber moldings (for as long as I remember the car would have windows frosted or misty on the inside on the cold days and fogged on the inside on the hot days). Sold it after I finished college as at that particular time I was working from home and was hardly ever using a car, so that wasn't much of an issue. Since starting a new 8-5 job however I drive one of those beige Korean cars and really miss my compact flickable Honda coupe. They don't make 'em like that anymore.
I’m sure it’s gone by now but I would love to sort this car mechanically out if I could afford it, I’m nerding out on this car it’s so beautiful. Alas hoovie wouldn’t have kept this hooptie so long so now I will cry myself to sleep watching Car Issues on demand. Great video? Great car.
mabye you should have an easy access kill switch built into this car for the battery energy draw lol
WHAT! FLOATING HEAD RESTS
Battery draw is probably a interior fan motor resistor! Very common on all BMW pretty much
changing it is a bitch
Fucking bmw and their half ass electricians
Battery draw issue is GM module capacitors require replacing, common problem with 20+yr old caps, $10 job. NEVER jump start these cars or try to run with low battery levels, this will give you more electronic issues. ALL the BMW factory electrical/mechanical manuals are available for free on line. Register the car at 8coupedotcom and read like crazy at bimmerforumsdotcom, 8erdotaug etc.

Yes, because that isn't the issue, it's the GM module capacitors as stated above. It's not the cars fault you diagnosed the fault incorrectly.
Hoovie, been a regular since the very beginning of your channel. Took a break and recently came back. Great to see your work being appreciated as much today! Onto my point: How about a CLS W219 review? I own an absolutely fully-decked out CLS500 because it was my teenage wetdream, and I love it to death. I don't believe it's as popular in the US, so your viewers would get a kick out of it. It's a stunningly beautiful car with a ton of forward-facing gadgetry inside of it at the time of prototyping, and it single-handedly started a new car trend among makers. I love it to death, and I'm sure you will too!
I have 4 brilliant BMWs and 2 not so but still solid. I use my turn signals every time, even pulling into my driveway from a residential street.
Always jump start a BMW via the terminals under the hood
Homerraas just curious, but why is that preferable to the trunk?
Theodore Smith simple, the battery is not fused, the terminals under the hood are, you can blow up modules or kill your throttle bodies
What about if you want to leave the battery on a trickle charger?
Adam N thats fine, that is just a few amps not 60-80 when jumping a car
Ah righty. Cheers
Batteries in the boot are more elegant then popping the hood.
BMW + Fluffy pup, 5 out of 5 would watch again.

Hoovie - ''I'm starting to adopt the BMW owners lifestyle'
Dogo - 'I'm out'
Glad to see im not the only one who talks to his dog like that! :)
Why in the world is the bottom button on your jacket buttoned? Not only do you never button the bottom button, but you buttoned the bottom button AND left the top open.
BMer driver!
Well.... if it's any comfort, I just bought a 92 850IA with some minor issues that will cost me around $5000 to fix, on top of that, I'm repainting the whole car, that's another $2000, then I'm gonna do a full job on the interior and leather, that's another $1500, 4 new summer tires, that's another $400.....oh, and, 2 new batteries, $300. Grand total: $9200. I bought the car for $6000, grand total: $15200...... yaaaaaaaaaay.........
mikealanzo spring for the $1100 set of summer tires / Michelin PS4; you'll be happy u did!
I'm going for Michelin Sport 4S, buying from a friend who works at a tire shop, the actual price is approx the double, incl mount and balance. The PS4 you're mentioning are a bit to hard for a comfort ride, too much noice, but a hell of a tire!
I hear you Erwin, but I'm beginning to question my purchase of this car due to all the costs..... is it really wort it in case I want to sell it someday? Will I get my money back? Will these models be worth more in 2 years when the new gen 850 arrives? Who knows?!
Perfect. The Sport 4s are good.
I got winter tires on my car ( Buick ) pilot primacy , Michelin P3 snow. Real nice + ❄️❄️🚗
Battery disconnects would make things easier on you, at least until you fix it proper
There are three body control units under driver's kick panel they are called KGM. Basically two are slaves and one master. I had to fix an 840i and an 850i with similar current draws and / or weird electrical act ups. I recommend checking them.
Hey Hoovie, here's how to get your car fixed, surefire. 1. E-mail German BMW dealership (say Wilhelmshaven since its a port on the NW coast) of your choice informing them you will be sending them your BMW over in a container and that they should send somebody to pick it up and drive it to the dealership. 2. Ask them to completely repair your car listing in detail what's wrong with it, 3. Ask them to ship it back to you same way they got it.
This video encapsulates the BMW brand perfectly. Fun to drive, great comfort and performance. On the other hand, the electronics are garbage long term and they are (as Scotty Kilmer calls them) bottomless money pit machines.
The head rests on the seats are levitating! :o
Filip lol. I can’t even figure out where it’s mounted. I’m really confused.
makes sense XD
ow shit, they are not levitating xD
Cool dog
Battery drain is one of the simplest things you can solve. So, here it is.
1. Get a voltmeter, connect it to the batteries. with everything turned off and the key out of the ignition it should read very close to zero. On your car it should be quite above that.
2. Remove fuse by fuse until the reading goes down.
3. check what is that fuse powering in the owner manual or online and replace/repair the part
4. If that doesn't work it must be some aftermarket stuff connected to that fuse and you will have to check/disconnect wire by wire until you find the culprit.
5. good luck
I have a BMW Z3, and when I bought it, if it stood for about 3-4 days the battery was flat, I thought it was the clock and other electronic things on the car that was draining the battery, until I noticed that the small fuse size boot light was always on, even when the boot was closed, hence the flat battery, Check on your BMW 850s and see if the boot light is going out or stopping on all the time.
Is the headrest floating ?
