I found what was causing all the electrical issues in my cheap auction Lemon Buyback Twin Turbo Repo (No Joke It really has all those things going for it) BMW X6m. But as we fix one issue quite a few crop up....

That's almost like dealing with a flood car. Actually it's a bit crazy to think that something so simple as a plugged sunroof drain can take down such an expensive car.
I've seen the same issue with an late 2010 model with idrive
How is this possible, do they even warn you?
Now in a Toyota you wouldn't find this. Just saying
@@alfy11111 It could happen in a Toyota with a sunroof. Just saying
That’s why I buy Toyotas without a stupid sunroof. Double blessing.
This is why I love M539 restorations: 44 minutes of actually working on the car, not 16 minutes of ads for some random auto gimmick.
Wtf, I get no ads from crac unless he does it himself in vid. And yes539 kicks ass
My god, half way thru the video I decided to leave and block the channel. Fucking 16 minutes ad.
I love both channels but remember this is all free content and bitching about ads is lame since they have bills to pay to bring this content to us.
I love the trolling of Rich's site.
TIP: fill the drain all the way with water and immediately blow it with air, hydraulic pressure will clean it. Repeat few times. Second tip: grease sunroof gasket.
Bad idea to blow it with air. 100% there is push-on fitting that is loose enough to get blown off by pressure and then you will have to remove the headliner to fix it.
Best way to do it is with hot water and dish soap and laundry detergent, pour the mixture in front of the tube and use a thick weed wacker line and keep poking and prodding. Whatever is clogging it will come loose.
@@rustler08 it's the most reliable way to clean it, you don't need big air pressure to do that. In the most cars it's holded by clamp under the headliner.
@@feluke8396 @rustler08 it's the most reliable way to clean it, you don't need big air pressure to do that. In the most cars it's holded by clamp under the headliner.
@@pirate2998 and if you’re wrong then you’ll be pulling the headliner to reattach that drain hose and that would be a nightmare. Not worth it at all.
I have unclogged a lot of sun roofs and was sitting here thinking you need to pull the carpet out. Glad to see you made it that far. So classic
Yes, with that much water what is on top is just the beginning. Tip of the iceberg.
I’m so proud of you for getting better at diagnostics and actually pushing a few steps further to fix cars. I am so stoked on your channel, and I’m loving the DIY style on the euro cars that get a bad rap for being needy.
I swear he has so much patience to fix cars like this I would’ve given up and junked it 😂
Still got a ways to go to catch up to Diagnose Dan :)
Gawd damn sunroofs! How many cars have been destroyed by something so simple as a blocked drain? I have had entire roofs rust out because of that problem. I only ask a roof to do one thing: keep me dry when it rains! Anyway, nice catch Sam. I am actually looking forward to hearing the full scope of the "car-nage".
You would think with all the sensors the have every ware else they would put on to detect the blocked drain
That is exactly the reason I will never buy a car with a sunroof. It's not a question if they start leaking, it's when. The same with the blocked drains, it's a when rather than a if...
Goddam it. That's is the very reason I will not own a car without rust holes in the floor. The water has nowhere to go and will eventually cause damage
@@meeder78 I wish it were that easy. Both my current cars have one .. not by choice... standard with the model I wanted. One car I have opened it about twice in 4 years, the other, NEVER.
@@marhot where I live it is almost always an expensive option to get a sunroof.
Good job 👍🏻….CAN bus issues can be a nightmare….a water leak is never a good thing, but having the wet carpet to point you directly to the modules on the floor is a beautiful thing when u start thinking about testing every module on the can bus
@Samcrac, Take the front wheel off, pull the arch liner, then pull off the rubber cross seal on the end of the drain pipe.
Wedge a screwdriver in to clear out all the leaf litter and rubbish, then you can clear it out from the blockage end. Not the top.
It's much easier.
Ask me how I know :D
just put towels at the top of the drain in the sunroof and around the seats, makes a heck of a mess.
As an e70 owner I agree with the above :))
@@damianwright6819 perhaps temporarily tape a running vacuum-cleaner to the top before and voila 2 for the price of 1
Sam, this: 👆!!
I always found pouring boiling water from the kettle down the drain holes works with older cars
at first i was like "no way they branded the title on this car because of a seat module"
Take the old school way of fixing the problem, drill a hole in the lowest point of the floor board..... problem solved!
Lmao
Surely the American way is to shoot it full of holes? UK.
Yeah i removed the drainplugs in my old convertible. Problem solved.
He could use that shot gun from before
...and avoid driving through water afterwards...
That was so exciting! Narrowing it down to a couple of modules was a great idea, I didn't believe it's a good idea because the relay is there to protect the car but sure enough it caused more errors to pop up than necessary. I gasped out loud when I saw the last shot with the water buildup and another module dangling in the pool, that's crazy!
That’s crazy that a BMW mechanic failed to notice this - glad you found the problem and it was so obvious.
Its such a common problem on literally every x5 and x6 from that generation.
I think by how easy he poped open that box.. someone else already diagnosed it, sam just taking credit and making content for this video... youtubers be faking so much...
I had the same problem with my E60 2.5i saloon and auto electrician could not find out what was wrong until I got a puncture and got my space saver wheel out the wheel well was full of water there was a module under spare wheel that I replaced from a breakers yard car runs great now I also took the rubber grommet out so no more water problems
Have to say that I’m impressed that you’ve pretty much nailed down what’s wrong with the car and that you’ve also found the source of the problem and a bmw couldn’t figure it out .
Sam, try to use vacuum to clear the drain line, the best way is to use a vacuum pump like for A/C system. Just use a jar or can in line to prevent introducing water into the pump oil.
Or maybe a hand operated vacuum pump like the Mityvac? Those come with an inline catch container and they are excellent for bleeding brakes too.
Hey Sam! Congrats on the result!
I'd advise you to buy oscilloscope anyway - it costs about 50$ (simplest one, that'll be enough for CAN diagnostics) and will make your life much easier in situations like this
And Carly don’t sell those😉
Yeah I was surprised by the $700 price tag; oscilloscope are quite simple technology nowadays
This is one of those classic Sam videos that I love to watch. Reasonable quality car for low dollars, fault find and fix.
Good on you Sam!
Cheers 👍👍🍻
The ending made me laugh so much, I rebuilt a flood title Audi about two years ago and had a similar experience. There was a Comfort Control Module under the drivers seat that got ruined by some water intrusion and once I replaced it all of the electronics worked!
Why the F did you upload this at 8pm central on a Friday night lol . Sam looking out for the forever alones among us
That car deserves to live, and you are the ONLY guy to do it!!! Well done, sir!
With that red blue color combination? Not so sure.
@@OMGWTFLOLSMH whaat??? I love that combination. To each their own I guess
Sam cracked the case wide open. Well done Sam! Why did not anyone mention this considering this is a well known problem, wow what a great ending! Love it!
Interesting video, aside from a third of it basically being a commercial. Uncle Rich wouldn't do us like that, Sam.
When diagnosing phantom electrical gremlins do the following.
Look for alterations from factory delivery first. Trailer plug wiring and trailer breaking systems, Entertainment units and alarm systems and headlights remote starters anything non standard and non factory.
Look for crash and water damage signs.
Look at fault code history to see what errord first and what’s connected to it.
Then look at what fuses you can pull to power off those modules.
Also if there are things that move and have wires that can break look at where they might break for broken and or shorting wires.
If you have a thermal imaging camera and you live in a cold climate or have aircon in your garage you can use it to look for hot spots in wires and components.
Every time a family member talks about keeping her 5 series after it's warranty expires, I point her to your channel. That always cures those delusions.
Your and Tavarish's work is one of the reasons why I work on my car by myself instead of having it done by a mechanic for a hefty price. Only car guys will understand what we do and why we do it.
Amen, I just had a small coolant leak. Mechanic wanted $600~ because the book says the intake manifold needs to come off. I fixed it by just removing the alternator and swapping the elbow, with a $4 factory one and it only took about an hour. A guy that I know at work said he just spent $4,200 (no joke) on “filters, hoses, and fluids”!!!!! I feel bad for some people
I know the rice bit at the end was a joke, but you might consider getting a big bag of Silica Gel desiccant to leave in the car once the bulk of the water is out and the drain is working. Just spread it out on some cheap cooking sheets for maximum surface area and leave it in there with a humidistat to confirm levels. The lower the level gets, the more water will get sucked out of the connectors with practically no effort. There is color changing desiccant you can get on Amazon for cheap so you can tell when it needs to be dried out.
Just came home from work and ate my dinner watching this. I need the next episode ASAP!
ASAP! Especially after that ending
Once again, Samcrac falls into a swamp and comes up cooking alligator steaks. Bravo!
My father had a recurring damp floor/sunroof drain problem in a brand new Lincoln. The dealer made a remarkable discovery when they tried to run a snake threw it: it did clear the drain but it could only be snaked from the bottom up! The drain path was horrible by design.
You have to pull that carpet up, expose the carpet insulation. I guarantee you'll pull out a few gallons of water. But then you'll have to dry it. If you don't want to pull all of the seats and carpet out to dry in the sun you'll have to hold the carpet up somehow and put some fans beneath it to let it dry for a week. Vacuuming from the top won't accomplish much especially involving mould.
Sam, gonna fix the title of this video for you: "Here's How a Little Dirt Ruined This Once $90,000 BMW X6M's Entire Electrical System"
That was some SMA Eric O. ninja level diagnostics there. So, congrads! I have no doubt you will unclog that drain, and that BMW will be back to its original glory in no time! Def a keeper.
I owned a 1999 540i for about 6 years. Beautiful car and a great drive. It was very reliable, but it did develop a very weird electrical issue at one time. The Climate Control system would intermittently start showing outside temp as -40C. This would cause the Air Con to start blowing really hot air, which could not be over-ridden. It had my Dealer stumped for a while, so they gave me a courtesy car and kept it for a couple of weeks whilst they investigated whether any other dealers has seen the problem. Turned out it was a short in the Petrol Tank Gauge Sender!!??
Congratulations - it is usually a physical problem that causes an electrical nightmare, looking forward to the next episode! (no thumbs down!)
Sam: instead of rice, bail and sponge out as much water as you can get; leave the rugs / padding open, and put a household dehumidifier in the passenger seat. Run the power cord out the window and seal the rest with a towel. Set humidifier to low humidity- 35% or so. Close all the. Doors and let it run for a few hours. Empty, and repeat until it doesn’t pull moisture any more. It works a charm and gets out the water where you don’t know it might be.
In colder climates a common clue there is damp sound deadening are windows misting up overnight. Rear light seals leaking is another common point of water ingress.
This is the problem with CANBUS. It's great when it's all working properly but it doesn't take much for a faulty module to corrupt the CANBUS data bus and make other modules data become garbled. It's fine if a module fails completely but a module that's not entirely dead, like this seat module, will cause a massive headache.
You can see why even a dealer wouldn't bother with it due to the time, and hence money, it would take for a technician to troubleshoot all the modules in the vehicle.
Hi Sam my F11 suffered from rear carpets getting damp and it was the door membrane seal. The tape you need to use is called Butyl tape. I’m not promoting my own video as I’m not a TH-camr but I posted one how to solve this issue. Many other users cited a ‘yellow grommet’ failure on the F10/11 models. This causes the front carpet to be wet. So perhaps investigate this area. Although as unlike the UK you are right hand drive you might not have these grommets as it was a cheap fix by BMW for left hand drive models. Good luck with solving your issue. I would recommend a dehumidifier running for 24hrs inside the car to remove the dampness in the carpets when your leak is solved 🙌🏼
Wow great job Sam I can’t believe you figured this out I figured it would be awhile remember the ax drain in the interior could be clogged and cause water intrusion.
Honestly its a big downside about having sunroofs they tend to clog and most people arent exactly car people and never know or realize these things, then get themselves in a pickle thinking they need a new car, to us its golden and easy flip sometimes and to them its just trouble
@@stinkysoulscanttellyou8695 I can’t agree with you more I’m always checking mine on my Audi just to be safe every time I was I check but ya never know sunroofs are a pain for what they are
@@martinmicheal4595 Is your audi the one in the picture? Audi a4 avant?

"I'll talk about Carly later"--Immediately goes into a five minute sales pitch for Carly!!!!
I can’t believe the bmw muppets at the dealership couldn’t fix this and auctioned it , yet a Sam fixed it 👍👍🇺🇸🇺🇸🇺🇸
10:33 that sound, you only hear some days before thanksgiving
The chicken farmer just went hi-tech on us!
That last part with the water. Incredible.
You know Sam.. I just realized that I would be you if my father wasn't a mechanic. He'd never let me buy half this stuff. Anyways, I really love that you do some really in-depth wortk on your vehicles. Most quit when it comes to things like problng wires. Awesome stuff!
That Sniper/Shotgun analogy is brilliant haha. "still gonna hit the target just one is more accurate"
The car may be running rough or feel like the dampeners are in the stiffest setting because the rear air shocks look aired out.
With the new module I wouldn't be surprised to see it raise itself out over night.
We had a similar problem with a 2013 1Series, flagged up by BMW UK as a "recall". This was concerning the water drains (left and right) in the plenum chamber becoming blocked with leaves, debris etc. This resulted in a LOT of water building up in the plenum, which would eventually reach the large grommeted hole in the left side of the bulkhead where the wiring harness goes through. Water would then run down INSIDE the passenger footwell, into/onto whatever modules were there, causing electrical havoc. Before booking the car in, I checked and found the water had JUST reached the lower lip of the grommeted hole, and luckily BMW had actually sealed all around the wiring/hole with some sort of semi-flexible sealant, which prevented any water getting into the interior. I cleared the plenums using a length of bent wire, making a "hook" on the end to fully open the rubber "flappy bits" of the drains. An enormous amount of water/dirt came out, probably about 20 litres. We had a very similar problem with a 2004 VW Passat, except that time water DID get inside. I noticed the front passenger footwell (UK car, so vehicle LEFT side) carpet was damp, at the same time we started getting some strange electrical opening/closings, lights on the dash etc. Same problem, plenum full of water. Our local VW dealer had seen this before, so the car had the seats/carpets etc stripped out, a space heater was put inside the car and it was put under a heavy cover for 36 hours to "dry out". We were LUCKY, as the water came within 5mm of getting inside the 2 modules at floor level. Phew!
A minute in to the first video, I yelled, "Flood damage!" I wasn't right, but I don't think I was too wrong. And yes, I know it is so much easier to sit back in my comfy chair and diagnose problems rather than getting out, fronting money to buy a car at an auction, and then fix it. But sometimes, you just sense things. :)
The driver's footwell was flooded. You weren't wrong.
You’ve had a result. Clear the blockage, dry the area, couple of new modules and bingo bango! 👍🏻👍🏻👍🏻
Amazed at how fast you are finding these problems! I used an oscilloscope for many years when I did TV and radio repairs.
I had a 2006 mercury mountaineer with the 4.6 v8 that had a bus interference issue and it was a cheap aftermarket coil going bad and causing electrical interference. It was causing my transmission to go into limp mode and was also making the electronic fan clutch to get stuck fully engaged and it you could really hear the fan pushing the air. I unplugged one coil at a time and restarted it until the transmission didn't instantly go into limp mode. Then bought new coils and replaced them and all my issues were fixed. At first it would randomly go into limp mode and only once every so often the fan would get stuck fully engaged when the engine wasn't even hot. But it wasn't all the time. I was fighting with it for a good 6 months before I figured out what the issue was. I would pull over turn it off and restart it.
BMW dealerships everywhere "quick write that down, write that down"
Super Mario is one of the best out there - brilliant guy that explains things better than most.
I can't believe after all that the solution was just a dumb computer box for the seat.
Like WHY does that even need to be a thing? My 1988 Supra has a ton of fancy seat motor functions and it's just a cable!
German over-engineering
So people can program their seats to desired position and module remembers. I cant think of any other function than that 🙂
@@clixium other functions like massage and bolster inflating while cornering so you dont slide out
Good job finding the problem
I also recommend checking behind the engine partitions (near brake booster & air filter) and removing the dirt/leaves as I guarantee that’ll be blocked as well!
Had that issue on my F11 and a footwell that filled was due to the stupid yellow grommet that degraded because leaves got stuck between the firewall and a cover and turned it into a swimming pool - not fun in the rainy UK
Wow. That sunroof is identical to the one on my 1999 Volkswagen Passat. Hilarious.
Why can I see this video
There are none so blind as he who refuses to see.
K-CAN is the Body CAN (K for Karosserie). On the other hand there is the PT-CAN (Powertrain) and F-CAN (suspension etc)
I have my suspicions. How is it that Sam is able to fix all these cars that factory mechanics can't? 🤷
Idk it’s almost like his whole business is based around videos fixing broke cars. Either he breaks it so he can make videos or he just spends more time then a customer or dealership would want to invest.
Buy back and get them to buy a new model... they make money on the new sale and then make money on auction sale.
shops not taking the time to properly diagnose... Electrical issues are the most tedious to figure out, especially with newer cars
@@austinh1028 people dont want to pay the time it takes so it doesnt get fixed. Simple as that, im not a charity
Too funny, Sam. Us Florida residents always have on shorts and a t-shirt with mosquito bites on your legs. LMFAO!
Sam try repairing the failed modules by using isopropyl alcohol. Get a tooth brush and get all the corrosion off the board and contacts. Chances are that you will be able to revive that board.
Also on the water you need to remove all the seats and carpet from the car and properly clean it then also clean the inside of the car. Fix the drains and ensure water does not intrude then replace the cleaned carpets and seats.
The dislike is still in Scotland
Canada as well.
Do you see my dislike on your comment?:) not personal.
America as well
@@jerrydwyer9057 no just on videos
For the same reason they banned This Modern Mansion. They have no balls.
That makes sense. When the driver's seat module glitches and thinks there is no driver present, IT ENGAGES THE PARKING BRAKE so it can't roll over the driver. A good idea, shared by Audi (they put the car in park if you try to reverse with the door open) but just...unAmerican!
Love the videos keep up the work, waiting for the day you finally rebuild a Audi rs3 and build the sucker to be a true beast👍
No joke I saw a really easy fix wrecked RS3 the other day sell for $36,000 (clean title) I am kicking myself for not buying it
@@Samcrac One of my dream goals i am working to achieve
Can I kick you for that too, Sam? 😂
@@Samcrac See my reply earlier.
You clean the drain by accessing the exit drain, which is behind the front wheel on the blocked side.
There is a rubber cross seal that can be pulled off, and then you can access all the compacted material in the bottom of the pipe.
Much easier to clean than from the top.
Ask me how I know!!
You will have it fixed in 30 mins!!
Greetings from Puerto Rico, (USA), I like you video because of how well you express and yourself and explain, you can see that you are a good person, honest and intelligent. I always watch your videos until the😅 end, God bless your family, Blessings😅

@@grandtheftautotune7715 i know what I said…
I had an e30 back in the day and it had the problem with sunroof drain holes. Had to completely take the whole interior out including the carpet in order to make sure the car was bone dry again. Also to put some paint protection on the floor as well.

Thumbs up 👍 Sam for getting your hands dirty in this video, even if it was only at the very end.
Owned a 1990 525I way back when. Out of nowhere it developed electrical issues. Traced it back to the floor drain in the rear passenger side floor. Unclogged the drain and vacuumed up the water. Issue solved
I see a dislike button lol

Sam, “the Sherlock Holmes of DIY car repair”!
The rich and sam banter is so funny makes me chuckle everytime i see it
That happened to me on my car. dealer fixed it, took the whole interior carpet out and put it into their paint booth with a dehumidifier for about 3 weeks while a new headliner was ordered from the factory.
Sam put a sail on that BMW you got a boat. lol
if you'd pulled the all the accessory fuses you would have likely found your problem, doesn't always work as sometimes the can bus could be shorted to ground in the module, but 99% of the time you have a solution in 10 minutes - whenever I see errors like this, I start with checking the power and then assume control signals.
You ended the vid at the exact moment I internalized, "holy s**t"... So much water
It wasn't the $40.00 that ruined the BMW , it was the leak going into the car that ruined the electronics.
Sam pulled out the Rob Dahm ending
"my approach is more like a sorn off shotgun" 🤣
I’m actually rlly happy u found the problem!
My wife's 2017 MB SLC 300 went into the limp mode several times and until I took a test ride with the senior MB tech no one would believe the problem. It turned out to be a small module that controlled the shifting! Sadly it was one of three problems detected right after the warranty ended, yikes! Good news is, it's fixed and now back in love with the car!
I spent so much money on parts trying to fix my own car and still not running lol I feel just like sam
We love your videos Sam. No reason to dislike. 🎉
It's like a flood damaged vehicle! Well done on tracking it. Have the same issues with a Grand Cherokee
OMG, BMW's high class of electrical engineering.
Moral of the story: never buy a BMW with a sunroof.
I'll give you credit for using Carly, and talking to the TH-cam guru guy. And knowing about the roof drain.
I use a bicycle brake cable inner wire to clean out blocked sunroof drains. It is stiff enough to feed down and flexible enough to go round corners.
So is weed eater line..
Certainly not a BMW - but I had 07 pontiac g5 that had a "blocked" (keep reading as to why it's quoted...) sunroof drain and I was too stupid to bother checking that... but eventually one day after a hurricane and the footwell to my car under inches of water, I ended up pulling the trim that lined the inside of the windshield on the driver side and I found the drain tube COMPLETELY disconnected and in two pieces. I plugged the two ends back together and duct taped it up, popped the trim back on, and no more leak. Few months later I ended up getting rid of the car since it wouldn't pass inspection due to rust.
I should have done that years ago as it was a problem I just let go... I would get a soaked left foot every now and then when I would make a turn... especially since I needed to work a clutch :D
People would dislike videos if they gotta see a advert within 3mins of a dam video!
Wow. That was a large amount of water. That said, knowing your on the right path to victory makes the journey easier. Nicely done Sam.
Having owned a BMW 5 series here in the UK that had a clogged sun roof drain and found a puddle in the drivers footwell one morning after a rain storm I can tell you all those carpets will have to come out and you will NEVER EVER get rid off all the water in those shaped sponge pieces. Buy new or s/h ones and save yourself a world of grief and time. No it does not just drain out even in Florida sunshine. Not that we get as much sunshine in the UK!
My blood pressure just went up last 5 seconds of the video Sam..
i used to dislike your videos bc i found most of them not usefull but this one is pretty good. keep up the good work and dont give up on this one.
