I love the trolling of Rich's site.
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.
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.
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.
Someone forgot to clean out the sunroof drain, rendering a $90,000 symbol of mighty German engineering prowess useless. Great video. Solution: Duct Tape around the sunroof, pull the fuse.
Or an afternoon with a welder and some sheet metal. 😆 Down with sunroofs!
@Robert Anna I'm thinking way more downtown. Absolutely cover the roof in clumsily torn strips of silver tape. Maybe changing color if I run out.
Panel bond.
@@bobmcl2406 Or a zip tie as it turns out.
@@gglen2141 oh sure, take the easy way out! 😁
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 :)
Hey Sam. Your videos are so much interesting to watch. As an ECU designer from Bosch, this takes me back to my field failure investigation sessions. About the seat control module that went bad due to water intrusion, you may be able to revive it. Try to warm the circuit board with a hair drier and then clean up the board using some isopropyl alcohol. Dry again and put it back. If the seat control functions were working fine from the beginning, it means that the module wasn't fully affected by water. Waiting for your next video on this BMW.
@@Jison9 Thanks Mono...👍
Yes sometimes residue from the water can cause micro bridges and voltage to flow
@@pollcrazy exactly
Power seats shouldn't need modules at all. Just use: some motors, some switches, and some wire. Lose all the cutesy features that make modules necessary. It is much easier to diagnose problems when there are no modules involved!
@@tempest411 True. But when it comes to being able to diagnose electrical faults easier and to ensure safety from thermal incidents, it is advisable to use such modules. Automotive standards also mandate certain features to come with advanced technologies that make sure safety of the vehicle is met in all circumstances. However I agree on your point about not complicating things and implementing them in simpler ways!
@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
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
Hi, Sam…as you now know, the seats, console and carpet all need to come out. Take the carpet to a car wash and throughly wash it, both sides. Any damaged padding can be replaced. Let all of this dry for a few days until you can feel no dampness anywhere. Wash the floor of the car with a disinfectant and let it dry. The front sunroof drain hoses run through the A pillars (with a few exceptions) so check the underside of the car to see if you can find the drain hoses-good chance that’s where the blockage is, either because of an insect or just dirt. Be careful with compressed air through the hoses, you could pop one, and they’re a lot of work to replace. Reassemble, and your BMW should be like new. Being in the auto upholstery, convertible and sunroof business years ago I dealt with lots of cars wet inside because of bad sunroof drains-it’s way more common than you’d think. Hope this helps! -Don
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 👍👍🍻
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.
Hey Sam - just a tip - when you're filming a PTC - go manual on the camera focus - stops it hunting for focus - 👍 😎 Also, what's happening with the DB9? Keep up the great work!
Also great in POV.. 😉 Ask his step mom
Or buy a real camera, I mean, how much money does this guy have to have?
It gave me a bit of motion sickness!
at first i was like "no way they branded the title on this car because of a seat module"
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!
Why the F did you upload this at 8pm central on a Friday night lol . Sam looking out for the forever alones among us
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 .
Great job Sam! Just went through this on my X5M. Only way to get to the drain is to pull the left fender. The drains tend to get clogged at the outlet. BMW recommends pulling/cutting the outlet end out completely or it will clog again. Watch using compressed air as you can blow off the fitting from the sunroof cassette. Drop the headliner a bit to make sure they’re still on there. Also, your leather dash is probably ruined near the A pillar :( Don’t forget about the rear drains! They clog too and ruin your trailer module, comfort access, and sometimes the amp! 💸💸💸 flow lots of hot water through the drains. the fronts should make an audible sucking sound or they are not clear and will overflow again!! Also replace your sunroof gasket
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!
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...
Just came home from work and ate my dinner watching this. I need the next episode ASAP!
ASAP! Especially after that ending
Great job, I knew you would figure it out. Love how you find something broke and you fix it. Keep up the good work
Amazed at how fast you are finding these problems! I used an oscilloscope for many years when I did TV and radio repairs.
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
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!
Now that's why I started watching this channel,.. Sam's wonderful analytic approach to issues!! Great session!!
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
Great video! I love following clues and finding success. Always sucks getting stumped but at least every issue is leading you to another idea 💡
Hi Sam, nice job. Had the same on my X5 E70, it was the rear window washer line that runs through the same area. It was leaking.
It could empty my washer tank without the pump being activated.
thats a good think to keep in mind, you would never expect that!
Interesting video, aside from a third of it basically being a commercial. Uncle Rich wouldn't do us like that, Sam.
Great diagnostic hunch Sam 👍 Super content, loving the story of this car.
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
I don't know, the pure dumb luck of sticking his elbow in the right place to detect water seemed pretty easy.
And Carly don’t sell those😉
Yeah I was surprised by the $700 price tag; oscilloscope are quite simple technology nowadays
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.
Well done Sam! I look forward to all your Videos.
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.
Lol. You went from saying "we have a wet module here..." directly to a pampers diapers comercial!
Sam - All it takes is one bad module screaming on the bus making it so others cant talk to each other. I had this issue with my Cayenne - Alternator went bad and it made it so nothing on that bus could talk to each other. I didn't need an osiliscope but I couldn't ping most of the modules until I pulled the bad module. Then like yours everyone started talking to each other
lol, that module was basically holding the transmit button down on the radio and shouting bad instructions. it never let go, no one else could talk.
Number one ztbn
no zero zzn
"screaming" is a very good way to put it 😁👍
Congratulations - it is usually a physical problem that causes an electrical nightmare, looking forward to the next episode! (no thumbs down!)
i love the way you approach the trouble shooting. I am no mechanic but am learning tons from your vids.
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
You found the smoking gun like Alex would say.... LOL dam freaking water. Can't wait for the next one.
Love the way you fault diagnose your car problems, a pleasure to watch!
I look forward to seeing how you go about solving this next issue. Thank you for posting.
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!
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.
Great informative video Sam!!
AMAZING trouble shooting skills! I am learning so much!
Better ending than some anime... thank you for the video Sam!
I really hope it ends good this time, with nice rims also!
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

Best video in awhile, excellent diagnostics
I've had similar issues on my BMW's. All too familiar with the clogged sunroof drain. Too bad you weren't around to save me a small fortune when I was having my issues!
The chicken farmer just went hi-tech on us!
Just like I said in the last comment in the previous video, water damage in the lower modules. How I knew was I had to repair the exact same thing on a BMW X6 M, Great that you found the problem 😎👍
Thank you Sam for providing great content always entertaining and educational.
Sam doesn't buy a flood car at auction and still basically ends up with a flood car.
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!!??
I’m actually rlly happy u found the problem!
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.
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.
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.
Well done Sam! A pleasure to watch and follow your channel as usual 👍👍👍
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.
Great video. I had limp modes under hard acceleration on my 2007 335Xi (I bought used with 70k miles on it). The local BMW dealership told me the limp mode was due to failed twin turbos and they needed to be replaced for $5700. I took it to a small shop and they replaced vacuum hoses for $142 in labor, that's fixed all my limp mode problems.
There's a reason people call them "stealerships".
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.
Love watching ure video keep up the good work mate
This has me excited, i need to see what comes next

Your video brought back painful memories. Not just a BMW problem !!!
Bro you have one of the best CZcams channels ever. Live your videos
This car needs a Bilge pump! Thanks Sam.
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.
Another great channel for diagnosing euro rides, is Diagnose Dan. He's very methodical, explains the issues in layman's terms, as well as his step by step troubleshooting methodology. He takes it a step further on occasion, showing how particular parts failed. Very educational.
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😅
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.
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
Excellent work, thanks
Keep ‘‘em coming. This is getting exciting.
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.
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!!

Sam, recently my e91 bmw had a problem on the can-bus... and it made the engine shutdown all of the sudden with lots of errors on various modules... and it was all because of lightbulbs... i installed led lightbulbs on the headlight rings... they worked for a week, then it came 2 errors on the FRM and JBE modules... ABS, ECS, etc,etc errors ... and can-bus errors on a bunch of other modules... put back the OEM old ones, and all errors gone.
One interesting thing though... it came old stored erros came to light as present... weird.
keep up the good work
Hey Sam love your videos there so interesting I Waite every time waiting for u to download videos I love the interesting information in your videos the way u fix and figure out what's the plms with the cars keep up the good work
use stiff wire like cheap coat hanger wire down the sunroof drains ,you want the wire stiff enough to push down but flexible enough to go round curves in the tubing ,also bend back the tip of the wire to make a blunt end so it doesn't stab the tubing
Love Carly for turning features as well. Great video
Yes! Thank you!
You are one of only about 3 youtube channels I watch consistently. Just great content. Thanks. (I hit the like and am subscribed of course)... :)
Kudos on figuring that out so quickly!
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
