- Ready for more **EURO-STUFF**?
The engine swap on this low-mile 2011 BMW X5 Turbo didn't go as smoothly as the owner had hoped.
At least it is running OK, but is blowing a fuse (short to ground) and setting two EVAP codes for the tank shutoff and vent valves.
Let's see where this one takes us, and if any expensive parts will be required....

I want to thank Ivan for his incredible help in finding the final issue with my vehicle. To everyone I fully knew the scope of work needling done in swapping the motor. The shop in question did not do any work to the motor regarding the spun rods. The motor was sent to a shop that specialize in rebuilding BMW motors and was fully rebuilt. The shop in hand was ask to just R&R the motor. Remove motor from chassis, remove components and wiring, Send motor to rebuild shop, And to reinstall components to and motor to chassis. I would be paying for such labor at the shops rate. I did not send to shop trying to be cheap. I sent to shop as it was a extended family members shop, and I want to support their small business. So I figured I would let them do the swap as the motor work was being preformed by a very well reputable shop BMW rebuild shop. I asked a million question regarding if they were knowingly and able to preform such work. They said they were fully capable of such task and handle the work. Fast forward from me dropping off a running vehicle to flat bedding it out.
The car ran fine outside the valve tap when I initially dropped it off, and had only two DTC codes referencing to the Vanos solenoids. Fast forward a year. When the motor is swapped. The car would not Start or Crank just the instrument cluster was responsive. When scanning the car for codes I got over 80 DTCs. I ended up having to flat bed the car from the shop as they now said they don't fully understand the BMW's. Upon getting the car back The first main issues was wiring to the main harness hooked up incorrectly. After correcting this issues the car then cranked, However the fuel injectors were not seated correctly and the high pressure fuel rail was not torqued causing gas to flood exterior of 5and6 cylinder. This cause me to have to replace all the ignition coils, Spark plugs, and Injectors in question. Also the Valvetronic was shorted when it received the wrong voltage so that had to be replaced as well. Transmission issues from the shop damaging transmission pan during swap, and a few other issues. I Manage to fix and correct all theses issues. Too be left with one last nightmare that I would have never figured out.
But it was really neat to see Ivan not only fix but located this issues in honestly no time at all. I spend days on it. he spent less then a hour.
What I learned, Always go with your gut. Just because someone has a shop and say they can do a job don't mean they can. Always do you do due diligence even if you know the person for business.
Apologies on the long comment.
Thanks for the detailed write-up, William! Hopefully the BMW will run trouble-free for many more miles :)
That’s awesome! I enjoyed the detective work. Thank you for sharing
A good technician knows his limits. At my shop, there's not much I can't handle. But you know what? I steer clear of European cars. I don't ever get them in, I freely admit I don't have the experience with them, and I don't have the tools required to properly service these cars.
That's honestly FINE with me. In my area, we have a pre-dominance of American and Asian cars. I have SCADS of experience on both, so I feel comfortable taking on those models.
I have never had a client get upset with me by being honest and telling them, I do not have the expertise to service this model. I want to make sure you have a good experience here, and unfortunately, in this case, it means telling you that I am not equipped to service your car, however, I am happy to refer you to someone who I know that does have the expertise, and someone I trust to send you to.
People appreciate up front honesty.
I've kept a 1999 Mercedes Ml320 alive for 207,000 miles and never would have figured out the swapped connector issue as well. Ivan is at times a miracle worker, and makes it look easy in the process. I've learned a great deal from watching his videos. Thanks for sharing your story William, may your BMW run for many hundreds of thousands of miles.
Did you pay the shop full cost
Makes you appreciate Japanese poka-yoke. I worked for a Japanese company and we had to always design so connectors couldn't get confused. Often we used connectors with different pin counts even though we left pins unused just to make sure someone (mostly the factory) couldn't get confused and swap the plugs. In design reviews we always addressed how we had done poka-yoke.
I'm working on my 90s Jeep right now, and I have the dash completely out (ac evaporator and heater core jeep). The only set of connectors that are same are color coded, so you have to be color blind to get this wrong. Now I just have to make sure I get everything I disconnected plugged back in because there is a lot of extra connectors behind the dash for the options I don't have.
The Japanese are a clever bunch. Our quality inspection devices - gauges of various kinds are designed on the concept of poka-yoke so they can't be used incorrectly by the operators.
I've done engine swaps. I've always captured the before and after codes. Told them these are the current codes. It's up to the owner for me to continue a diag. I tell them my rate. No estimate on $ figure. I don't want to get stuck with a 4 hour diag and I quoted him a low number. If they start arguing. My diag is over. If the code was my cause. Such as a sensor not plugged in. I will owe that up. Only wish I had a pico on my tool list. But crap. I'm getting to old for this. Anyhow. I've learned from Ivan. Mr. O and others.
A sign we have in our shop says "If you think it's expensive to hire a professional, just wait until you hire an amateur". This shop clearly got in over their heads and although it hurts, make it right
Great saying!
I followed this guy over from SMA, I'm glad I did, they both do a heck of a job!
same here
same here, they both use common sense and their brains keeps up-to-date and well trained.
Same here, surely having connectors the same (are they not colour matched?) is just asking for trouble. Shop could have marked them during dismantling.
Me2
You live and you learn, it’s called common sense. Stay away from doing business with relatives, a bad business outcome can ruin your family relationship. Only deal with shops that guarantee their work in writing and before proceeding with work check out BBB complaints and comments. In this time of scams and Covid, even taking those precautions won’t guarantee you a satisfactory outcome. When you find a good shop and competent mechanic that tells you the truth and doesn’t gouge you on price, support them and tell your friends and family about them. They will thank you for it.
Marking connectors is a must when doing an engine swap as demonstrated by the multiple wrong connections made. That BMW uses many of the same connectors for multiple sensor and computer applications further complicates the situation . Absolutely OUTSTANDING! case study your patience always amazes me. Bravo !
Thank you Carl!
Spoiler alert
Nice job Ivan! All the problems are totally on the shop! Sounds like this was the shop's first BMW swap anyone with half a brain would have turned it away!
You sir are making mechanics that can’t do anything without a scan tool look like amateurs. Great diagnoses
The scanner is only one piece of the diagnostic puzzle...an essential one. :)
I used to hate BMW/Mercedes/Audi/Volkswagen….but i’ve made so much money working on them i’m beginning to like them a lot more. I’d just never own one.
My wife bought a new BMW in 2016, absolutely the most unreliable car we've ever owned.
If the shop that did that swap had any pride or ethics they'd just eat it.
They'll live..
I ran an air conditioning and heating company in Houston for 25 years and every once in a blue moon we'd blow it beyond recovery and I would just step up and eat it...
I think there were 4 instances of that over the 25 years.
It sucked and it hurt,, hurt the pride and the wallet,,, but I would eat it..
If somebody thinks your an idiot because you screwed up has never done a damn thing. Personally after over 35 years in the business there's no way I would have took on that ulcer but hey everyone loves a challenge even Ivan.
@@prmayner Agreed
an you got more jobs
sometimes you have to get hungry dealing with Euro Junk
@@Monza62000 It's somewhat fuzzy now but I did save at least 2 customers..
Mechanic 1 "we got an extra connector here"
Mechanic 2 Stares at if for 5 seconds. Pushes it out of sight. Exclaims "that's lunch"
"Good judgement comes from experience. Experience comes from bad judgement."
I have done BMW engine swaps. 6 cylinder even the new turbo N20 4 cylinder engine. They are not that hard to do and get right, But you have to have the right mind set to do them because they get complicated real fast cause of the wiring and connectors.. The shop owner saw dollar signs $$$ and thought his 10 $ per hour guy could do it.. that is where he made his mistake🤣. All of the damages is 100% on the shop owner. If the car drove in and wouldn't start, they damaged the parts, Simple easy, the shop owner is actually responsible for this diag charge and repair as well..
That was quite a challenge! After 2 bad diagrams, and that much aggravation. It really takes a deep understanding of electrical diagnostics. No way I would have pulled that off, on my own.
When working on a BMW, you really need to get ISTA (diagnosis scanner with inbuilt wiring diagrams) ISTA is the OEM diagnostics program. I can give you a slightly outdated version free if you like. (of cause you will need a Enet or Dcan cable to connect fra OBD to laptop)
To paraphrase H.L. Mencken:
Every problem has a solution that is neat, simple, and incomplete...
I learned the hard way on some of these older cars. I had a neighbor pull into my driveway, didn't really know her but everyone who drives by my house understands 'I fix things'. Her car was making 'some noise', so I figured the polite thing would be to pop the hood and just give it a quick look/listen, provide my solicited opinion. I leaned in and some obscure plastic evap component just crumbled when I touched it. I lost three hours of my life and about $75 between procuring the part and playing parts store hopscotch. The obscure noise was her throw out bearing and clutch were basically toast.
Paying the experienced technician is always cheaper than the cheap mechanic!
Yeah absolutely family or not you need a proper shop with proper people who know how to work on these complicated car's
that's a **mechanic** - won't find many of them at dealers
Crazy! I agree greatly on quoting more than book time. Everyone often forgets that book time is based of performing the procedure on a brand new car with no miles. Things do not always go as planned.
Yeah especially if you’re third in line and the first two we’re butchers.
I have never seen a motor swap go as planned. There is always something unexpected to deal with.
As a primary Euro tech myself I've seen a lot of screw-ups by other shops who end up bringing it to us to fix.
Sad that shop did such a botched job that it cost this guy probably way more then the cars worth.
I'm sure this owner won't go there again.
Great diagnosis and finding the problem at hand. For future reference, pop that air box off it's super easy. Remove the hose clamp and pulled upward it comes right out just on some rubber holders over plastic pegs. Gives you more room. You can also pull the intake manifold back a good bit to access under neither for starters and what not..
super easy, 11mm on the intake nuts/bolts and Remove intake piping and the wiring retainers.
My comment is everything that all the other people commenting stated. In other words GREAT JOB IVAN !!!!! 👍👍👍👍
I would have eaten the cost of engine swap if I was that shop. Also if I would do a job on a vehicle I am not familiar with, I research the crap out of it first before I would even quote it. Second I learned along time ago label all connectors when I take them apart. Also I baggie all nuts and bolts with labels where they came from. Makes things a lot easier when reassembling.
yeah, and be totally transparent with the customer that this is your first rodeo with this particular car model and for them to expect a bumpy ride, that you'll work with them the best you can, but when it's all said and done, they're going to pay for at least half of your mistakes (or you're just doing it mostly for the experience and to help out a family member).
But in that latter case, that's when you especially have to work methodically and double/triple check everything, take plenty of notes/pictures, etc...
It's called the slow fast way (instead of the fast slow way)
The greatest demonstration of a mid amp bulb for diagnosis. When i worked on
AC devices back a while ago, TV, VCR, etc, i had a 300 watt bulb cord with switch setup in series with the load on anything blowing fuses.
Unfortunately the shop was at fault in this case. But hey shout-out to the owner for doing his home work and "unscrewing some of the screw-ups" to get the car running again🚙💨💨💨
This is the very reason I sent all the Euro customers packing. I was going crazier.
I always liked the trouble shooting end of automotive repairs, the problem with this is the Jobs that come in, is either screwed up by the customer or by friends of friend garage. As book time !!! THROW the book out, that's for factory assembly where everything is new.
Great diagnostic think before action.
... everyting is new --- and the person doing it has done it before
I diagnosed one of those same year and make. It had a bad timing chain and the engine was knocking. Pulled the valve cover and it was seriously sludged up. Vehicle only had 120,000 miles on it. Those engines must be maintained properly at all costs. Thank you PHAD Great video
Mmmmm........... Electrical work. My faaavvvvorite. (Rolling eyes)
Solid work Sir!!
Bonus comment, bet they're not "friends" anymore. ALWAYS be nervous about friends and family automotive work. It always seems to get F'ed up. It's very rare I've heard of those situations with a happy ending.
Except friends of Ivans.
Here is an idea how about labeling all the connectors you are unplugging so you can reinstall them back properly.
Should of called Scotty to remove all that plastic crap!! 🤣🤣
I've worked at BMW manufacturing in 2011 so this baby slipped by me on the production line for sure. There's 5300 spot welds in that car. It also has rivets, MIG welds, glue and hand brazing holding it together. I am particularly proud of the sides body panels since that was my section to watch over day in, day out... B-pilar and door braces have armor crash protection.
It is one hell of a fine made car.
Ivan for the win!!!! He can fix anything.
Ivan the car whisperer performs his Magic again. The shop should eat the cost of there carelessness
Ivan is a great mechanic. I wish he could fix my cars.
any engine swap i do i use good masking tape to label all wires hoses and brackets and write down the order things come off
Pictures
Remember it was there for a year, labels can fall off tangled,markings would fade away etc
@@mikefoehr235 well on BMW pictures won't work really, because most if the connector looks the same, like the valvetronic plugs are the same can reach the other sensor. And some of BMW harness doesn't have a spider web, meaning one plug can't reach a next plug socket like USA and Japanese cars sadly.
Love watching your approach to these issues. I’ve been a German tech in the past and having faulty diagrams wasted a lot of time. Shop should eat the repair unfortunately.
Wow, very interesting to watch. That diagnosis wasn't so trivial. Excellent outcome as always 👍👍👍
You fixed that problem. The shop that changed the engines is responsible for their work.
When my Dad had his automotive repair business, a guy came in with a problem in his vehicle. He proceeds to tell my Dad about what this shop and that shop did to the vehicle. My Dad closed the hood and told the guy to take it to someone else! You don't have to take a problem vehicle like that that others have worked on.
When I worked for the L.A. Dept of Water and Power, I saw vehicles like that. Other DWP shops worked on them, then we got the problem! There were several of us in the shop and we helped each other. We got it fixed!
Sounds like the owner has been to hell and back with that. I'd say the other shop should swallow the cost but will mean completely burning your bridge with them. I swear I've got PTSD from that BMW bong sound 😁
Remember Ivan saying the owner was a BMW enthusiast? Wonder how he is feeling right now about his beloved BMW.
That sound can cause a quick heart skip😂
In german cars wiring color is important as it corresponds to DIN. Red is always hot. Switching colors at connectors is not a common thing.
90% of shops are not honest or stand behind their work like Ivan would. Every Dealership experience I have had was full of excuses and overcharges, sad since I have zero confidence in any shop now. I wish I lived closer to Ivan!
Definitely on the shop, I am a Mechanic at my Stepdad's shop, the first time I dropped an engine out the bottom the craddle stand wasn't setup right...I had the stand rotated 180deg, dropped it to the floor, the shop bought a new oilpan, oil pickup tube, cradle got bent and a couple other items that were mainly just a cya...the customer was sitting in the shop at the time b.s.ing with my stepdad...they both shook their heads laughed and came over to help me get the engine up off the floor. Thank God they both are laid back old timers...all said and done the shop spent $800 on parts and an extra 5hrs labor...I was so pissed about it yet had to suppress it and maintain what little professionalism I had left...I don't even remember why I was dropping the engine in the 1st place...lol good times as a new mech. Now I'm getting into the more deep diag's and finding things learned watching you, Scanner Danner, South Main Auto and the one ford guy that I can never remember the name of...seems to be the only ford guy that comes up with ford in the channel name...I digress! Thank you for all the great video's and thank God my Stepdad stands behind our work. He would have paid you for your time fixing this if it was our mistake!
i all ways when working on a bmw and have to disconnect wire's put a bit of tape with a number on to both side's of the connector save's a lot of time in the end,nice job on finding that 1
"It spun the rod bearings, apparently that's what happens..."
German engineering!
4 months later... I didn't realize I had commented on this before. The "like button" wasn't pressed, which led me to believe that I hadn't seen it before. Still stand behind my original comment!
"It spun the rod bearings, apparently that just happens" cool cool
Ivan a very thorough investigation on this issue, great job.
Just remember folks not all shops have a Mechanic in them... Great work like always IVAN👍👍.
& great job, Ivan, but unfortunately, i don't know why BMW makes things complicated with the same shspes of connector!.but hey, big ups, because your Diagnotics has actually enlighten Me, not to play around with bmw connectors!
Geez , all those problems the owner is exceeding the value of the car worth . He must really love that car !
Obviously, the shop should take responsibility for the damage they caused. The fairest solution would be to refund the cost of the work they did. At least that way the customer would be left with pretty much what the total cost would have been had the job been done correctly. It is a compromise.
I don't want be married to this thing, if only I'd said that 2 marriages ago. Nice work Ivan ! Very entertaining to watch.
I started watching your TH-cam because my truck is not wanting to stay running. Then I just kept watching your videos to learn more about the wiring and electric side of cars. It'll be nice to learn from your videos seeing how you do an amazing job of braking it down. Just saying thanks for taking your time to make these videos I know I am learning from the right person again thanks.
Great video. Definitely the shops fault. Over a year.... that's crazy! Projects like that happen in body shops all the time when cars are in the shop on the back burner for years even though the owner has already paid.
Freaking amazing Ivan! You did it again, victory!
Watching you has caused an upgrade in my electrical test equipment, and made my life easier. Thanks. And prevented me from even thinking of modern eurotrash as a DD.
I am more of a Mercedes diesel guy, but I bought 2002 BMW 5 series and had do an engine swap, that went well and I have been driving for many years. I recently bought 2012 750Xi as a project. It has the notorious 4.4 dual turbo V8. Engine on one cylinder has a bad rod bearing. So need to pull the hopefully I will be able to find a replacement engine. Scarry part is it is a lot more complicated the 5 series. Just will take it one step at a time.
Good find, Ivan! The vehicle owner is no slouch either I have to say! As far as who pays for what? That's what small claims courts are for! Suing for damages is pretty straightforward.
I agree, the customer gave him an out to not do the job if he’s not confident doing it, also it’s ok for a shop to say I’m not confident doing it because today’s cars are so complicated and need so many special tools can’t expect a shop to be able to do everything. Stick to what they know how to do
You don't know what you don't know until you know it.
I've done a lot of things with cars and trucks that turned into something way more complicated than I thought it would be. I have a lot of specialty tools just to solve those problems. The shop basically did the swap but screwed something up in the process. So it wasn't like it was way beyond their abilities.
Ivan the BMW owner is as patient as you! Having a car in the shop for a year would be hair pulling for most people coupled with the original engine swappers getting so much wrong would make most of us want to scream! Hope the engine swapper takes a hit to make up for all their mixups.
So the 7.5 amp fuse was stopping the mistake becoming a bonfire, lucky the owner only used the correct fuse.
The small repair shop man should have known better not to take on a job he knew nothing about :-(.
An apology and no charging the car owner would be the honorable thing to do.
Ivan, if you screwed up (Fiction) you would have done the right thing, i know you would.
a real bozo would have swapped that fuse for a dime and noted which wire burned up, so he could find the short!
I am so glad to see a vehicle that was worth fixing, not a jeep or something with 250,000
miles on it, my Boss spent almost $10,000 putting a new engine in his 750i, and it
still had problems.
great case study my friend!!!!!! i watched the whole way excited ........ lol
That was great ! Super skilled step by step electrical diagnostic procedure ! Incredible instructional skills as well ! Thanks for letting us learn from you !! 🙌🏼
Yes these mills do spin bearings, due to oil starvation usually. Maybe if they had a dipstick...? Or perhaps not a 6k oil change interval? Anyhow, the very few times I do Euros, I use only OE diagrams and code descriptions. Great detective work Ivan! Shops of integrity are tough to find. If the owner decided to take that shop to court, he'd probably win, but at what additional cost?
Lol. 99.9% of car owners today never check their oil anyway, which is why they put the electronic sensors in to begin with. Hell, 1/2 of them probably don't know how to open the hood. I do agree that the oil change intervals are way too optimistic, but I also wonder what people are using. They buy a $50,000 car and then somehow complain when Mobil 1 cost $8/qt.
BMW engine swaps are actually very easy. Ive done several in 1 day. Never more than 2 days. I cant imagine why they had such a hard time.
The initial code, 3162 and 3157 are the BMW decimal codes...
It does not translate directly to "P" code by just adding a "P" before the numbers...
There is tables online that shows a "translation" or a match if you will, from the decimal code to a "P" code...
Hope that has not been covered later in the video, otherwise this is a pointless comment...
😋🤣🤣🤣
Now back to the video...
👍👍👍
Thanks for the tip! Question is WHY? haha silly BMW!
@@PineHollowAutoDiagnostics
Most systems I believe just report to the scan tool the hex or decimal code...
It is then up to the tool to look on their database and translate that into a "P" code...
Most of tools, on BMW still just show the decimal code...
Some tools, you can select that decimal code, click details, or something similar, (depending on the tool...), and that then shows other details including the "P" code...
Mercedes for example, does the same...
Quite a story, and I imagine unforgettable experience for this BMW owner. From what was to be a straight-forward engine swap, (disassemble, repair, reassemble), the process accumulated many 'introduced' electrical faults by not ascertaining connector orientation and placement in the original configuration. For some time (and some time ago) I repaired videos and CRT televisions, and remember that some of the most difficult and time consuming repairs involved faults that were 'introduced' by a 'do it yourself' customer who has worked on it, and 'given up'... What this job really needed was the thorough and methodical examination of the wiring diagram to the calibre of 'Pine Hollow Diagnostics', which completed the task in the time frame of a YT post...
Very nice setup using the Power Probe and the lamp.
Power Probe? Haven't used one ever... But test lights are the best 😁👍
I appreciate that people like Ivan and Eric O don’t mention the names of the “other shop” because we aren’t getting the whole story. It’s true, some of the things the “other shop” does (especially on SMA) seem pretty dumb. But, in this case, did it take a year because the owner kept telling his friend, “hey, no hurry, whenever you get to it”? Did it suddenly become urgent for the owner whereas it hadn’t been for the last year? Did the other shop just give up and tell the guy to come get it?
I’ve been around long enough to know the truth is usually somewhere between the stories both sides are telling and in cases like this, we’re only hearing one side. I enjoy these videos for learning about troubleshooting, diagnostics, theory, etc. but get leery of delving into, essentially, the civil legal system.
I know this is from one side my side as the owner. But what you hear is the whole story. I brought the car as a extra vehicle so there was no urgent need for the car. The shop had the car for a year however I never pressured on when it would be complete as it was just a be extra car and we were in COVID. So the time to complete was what it took them. There was Zero hold ups on my end. I never rushed them in any way.
When I flat bedded my car out of the shop. It was because after the motor swap, and all the trouble codes He decided to tell me he is not use to working on European cars. But I ask this prior to dropping it off, and he said he knew how to work on the bmw and do a swap. He then told me he did not understand their electronics and he was giving up. I explained no problem at all I am a very fair person. So I told Him I would pick the vehicle up, and we would have to hold invoice to I figured out what the cause of NO crank, No start, and over 80 DTC's. Once I got into the engine bay The Issues was as the video explained plus DME improper connection, in doing so it shorted my valvetronic. He did not seat and torque the injectors and rails properly witch cost a whole host of issues. As all the times he was trying to crank it was dumping fuel in the cylinder walls, and etc.
Moral is he had 3 mistakes. 1 Saying he can do the job when he knew he could not. 2 Did not hookup the wire harness correctly, and 3 did not tourqe to spec. Those two little last steps cost me in the long run.
I used to race BMWs for about 15 years, so I've done more engine changes than I can count. Changed a few on street cars for friends too. Given their complexity, you don't disconnect a single connector on a BMW without labeling it first. How a shop made a rookie mistake like that is beyond my comprehension. Every swap I ever did started on the very first crank, and I could change the race car engine by myself in 10 hours.
Ivan you are one of the best if not thee best gremlin chaser on the tubes! Your process is really amazing.
The debacle the owner experienced shows a good mechanic is worth their weight in gold. Maybe things are different in the US (I’m from the UK), but unless specifically agreed otherwise, I’d expect them to work on a ‘no fix, no pay’ basis, particularly as they caused damage whilst attempting the work they were contracted to do.
If your shop was anywhere near Louisville, KY, I'm certain where i would take my 4 BMW's for service (4 of 8 vehicles). You're certainly a competent diagnostic technician, that's a big plus, you also get a super + since i can see that you also have a lot of good sense, I see at 21:10 that you do not want 'NO MORE BULLSHIT.' Neither does the vast majority of people in this country, we were scanned..
Ivan you Certainly make it look Easy! Love the videos & hope to pick up a Fraction of what you Know!
Wow Nice Job Dude
I remember the first time I changed an engine, at around 18 years old. I knew relatively very little about engine electronics and mechanics then. But, the very first thing I did was grab a roll of masking tape. I put a piece of tape on both sides of every connector, and wrote a number on each one.... It made the whole process less intimidating. I think that engine in my Grand Am was called a Quad Four or a Twin Quad... Something like that.
Break My Wallet. Good one. Bring Mechanic With
I learn the hard way to mark connectors especially on euro makes good video
Ivan is a master mechanic. Amazing he fixes everything.
Nice detective work Ivan.
Look, I suppose if BMW can fit the same connector in 15 different places they will do as a cost cutting exercise. It did not help to have wiring diagrams that conflict with each other. Well done though Ivan, another good diagnostic outcome.
excellent troubleshooting as usual
I once diagnosed a friend’s BMW E36 with a crank no-start. He had taken it to a shop for a clutch and it ran fine when he took it in but the shop couldn’t get it to start after replacing the clutch. Every once in awhile it would turn on for a few seconds and run like crap before stalling. There was no spark. The ignition coils were receiving ~8V and tracing the wiring harness back to the connector found it only partially seated. Seating the connecter fixed the problem. My friend had been chasing a potentially bad engine ground for days which I immediately ruled out within a minute of pulling up wiring diagrams.
I had a mini-trail Honda like on your poster , yes I am that old.
I'm guessing the shop did not photograph and/or properly label all the connections prior to removing the engine?
You then factor in conflicting wiring diagrams - whadda nightmare for everyone!
However, most of the fault lies with the shop and so in all fairness, they should credit the owner for his out of pocket costs to remedy their work.
Thanks Ivan! This was really good case study being that I love to try and repair Bmws every now and again. The shop should’ve known to at least take pictures of any components/connectors as a reference to where things went so that reinstallation would go smoothe! They pretty much dropped the ball and should be thankful that they didn’t end up in court over this one! Post some more crazy Bmw vids should you run across anymore! 😎
haha yeah Greg, every BMW is a learning experience for sure!
BMW makes diagnosing and troubleshooting their systems opaque purposely. They don’t want diyers and independent shops competing with them in repairing their vehicles. You have to diligently research even dealerships now days because the experienced techs have aged out of shops and the replacements have no field experience.
@@slimdugger99 Great way to break it down for me! Although they’re complicated I’m gonna continue to do small repairs here and there and do what I can. If anything comes my way to crazy I have Ivan on speed dial lol
Your the man Ivan! Great logical sequence. Actually, I can't believe you found all those connectors. Why in God's name would ANY manufacturer install connectors that could physically get put together wrongly. ? This makes no sense. Unless you are a specialist in European cars I don't know why any shop would touch a European car. Heck, can't even get an aftermarket wiring diagram or code identification!!! I smell sabotage.
You're absolutely right it's on the shop, unfortunately that's complicated by the shop being a friend, German electronics are no joke, consider VW, Mercedes and Audi, engine swaps are not too be taken lightly
You are great at what you do.... Love these videos....
you are a dangerously clever dude....its lucky for the general public that you aren't a bank robber....you'd be like The Penguin or The Riddler
The shop that replaced the engine should pay for anything the owner did. Sue Job!
Had a customer buy an engine from our shop (2005 PT Cruiser) and could never get it started. After towing the car back to my shop I found they swapped the cam sensor and some other sensor under the intake. Got it running!
This is why you take videos and images of everything, before you take it apart, AND as you remove things. Lots of manufacturers use the same connectors at the computers, ALWAYS mark each for proper identification and replacement. Especially, if you've never done this kind of car before! Pro or DIY, same thing applies!
The most important thing, is to label the connectors. photos can trick you a lot. with a label/sticker, never.
Check out the short to ground backwards with a diode test on the cabling .
How?
once again, Ivan is amazing!
This vehicle reinforces my statement: I'd rather own a Chrysler with no wheels than drive a BMW. Chrysler may have flaky ground issues but at least they choose connectors properly.
A family friend says:
A: "BMW engine swap? No problem!"
B: "BMW engine swap? That is a pain in the ass!"
C: "BMW engine swap? It's gonna cost you!"
Guess which one you should avoid!
Avoid BMW's. Keep it simple.

The shop should stand behind their work or pay for the fix
My #1 rule is: Never take a BIG job to a friend’s shop. It makes it tough when things go wrong.
Over the years of owning and repairing BMWs I have come to the conclusion that BMW deliberately design things to confuse mechanics.
They re use fault codes so snannars will often come up with the wrong descriptions. Their activations on the scan tools are often incomplete or test a system in a non intuitive way. Not all outputs or inputs have a pid.
Even changing the brake pads can catch you out because the car is watching you disconnect and reconnect the sensors. If you don't they have set it up to show a correct reset for a few 100 miles then show a replace pads message again. I think this is a deliberate plan to create frustration in the aftermarket and to go back to the dealership.
