Clogged sunroof drains can allow water to enter the interior and accumulate under the carpet where various control modules are mounted. Over time, the accumulated moisture can damage the control modules.

haven't fixed it yet. at a loss to know what to do. car is dead in the water, so to speak. car was flooded front and rear seats, body control module is shorted. vacummed the water out and shoved the car in the garage. I don't have $$$ to fix. Shouldn't VW recall these cars and fix these drains and components?
also had the inside of my passat flooded...found drivers side rear drain hose for sunroof kinked between some metal section in the fender opened that but still getting small amounts of water when it rains real hard.... replaced trans. control module under drivers side carpetand got the car to start and run but still need to find the comfort module and replace it so i can get my windows to work....if anyone can help me with that...i would appreciate any info anyone can give me...
Water under carpet drivers side.
Had this occur 5 yrs back. Entire computer ($5K repair bill)system "flooded". Shocked to learn as have car regularly cleaned; luckily covered under insurance policy. Furious that VW tried to blame me. Filed complaint on-line with NHTSA.
I have a leak but no damage in the carpet. What to fix the sun roof or my interior
My module malfunctions. Drain under car battery clogged and flooded module located on the driver's side floor. One by one things have stopped working...windows, power sunroof, gas door latch, remote start, heated/power mirrors, vw key malfunctions etc. I think VW should recall and fix the problem. POOR DESIGN...WHAT WERE THEY THINKING !!!!! I found where I can get a new one online...cost about $300.00.
The car will not start -after heavy rain - clogged drains in sunroof cause leakage to inside of car to control module,
Leaked to the passenger side module and car ran like crap. I got that fixed, sort of. The transmission still shifts rough. The driver's side module got wet about 6 mos. later and I lost interior lights, central locking sys., etc. which I have not fixed because to cost is prohibitive. The car is only worth 4k. I can not believe this car was designed by German engineers. My dog could have done better....
I have water running down the passenger column and down to the floor. The water gets in and puddles under the seat.
Complained of rug being wet on driver side since got car- been in shop 2 weeks still not fixed. Think I got a lemon
In heavy rain, passenger foot well floor fills with water. Carpet is routinely submerged in water by a few inches. Vacuuming it out with a shop vac produces several gallons of water. Strong mold smell, suspect carpet and padding will have to be replaced. ECM frequently submerged. If it is damaged, car may be a total loss due to repair costs and cost of remediation of the issue, water damage and mold. No solution yet, but have seen discussions and instructions for clearing the drain lines. Aware there was a class action settlement over this, but the website for the settlement is down.
TCI transmission controll module destroyed by massive water leaks, Water leaking in the passenger side soaking the contents of the glove box collecting in the rear floor pan. It will be the sunroof drains clogged or a drain under the battery or both. The tci is $1400 farfagnugen you !!!!
Leaks inside around holes of sunvisor mounts when it rain.
Wasn't sure what was going on until I read all these reports! Going to have a look.
I have a VW Passat 2008 and when I moved to a house with a unpaved road I started having issues with water on the floor of the passenger seat. I investigated and discovered that VW has issues with drain been clogged. I used clean drain liquid gel and bleach, it helps for a short time. I'm afraid I will have ended up having issues with the modules underneath the seats.
Bought used from dealership, was leaking as soon as it rained..found a piece of carpet cut on passenger side where leakage was so it was known before I purchased it. Had it at garage 8 times to fix leakage, when I cover the sunroof with plastic water does not get in. Did a lot with sunroof, blowing out drains, gasket around sunroof sealing etc. Still leaks cannot get it fixed.
Whenever it rains heavily, my driver side carpets get soaked. Don't see where the water is coming from.
water leak from the clogged sunroof drain into the passenger vizor and on the floor
Roof leaked and comfort module stopped working. No windows, no interior lights, sunroof won't open or close.
the interior of the car STINKS!!! We have ripped up the carpet and found mold. Cleaned the interior again and again but it still stinks. I think this must be the problem!!
