Volkswagen Passat Water From Clogged Sun Roof Drains May Damage Control Modules

(61 reports)

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.

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... -
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.... -
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. -
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. -
Water under carpet drivers side. -
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 !!!! -
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? -
The car will not start -after heavy rain - clogged drains in sunroof cause leakage to inside of car to control module, -
The instrument gauges went crazy showing Brake issues, airbag, etc. When I checked under the passenger seat it was wet. As it turns out the entire passenger side was deeply saturated and the TCM was submerged and soaked. Now that components are dry I all need to find all the drains. The front two which are in the hinge of the front door had been clogged and as I squeezed them they unloaded a sizeable amount of water. Where are the other drains? -
2005 VW Passat - After a heavy rain August 2014, I found the driver's side floor full of water. There was no water signs anywhere except in the floor. VW dealership & body shop couldn't find a leak; said it would be very expensive to take out seats and try to find the leak. Nothing was done. In January 2015, I had water in the floor again. The dealership service department took the sunroof apart, did damage to the driver's side upholstery, visor, garage door opener buttons, left greasy black hand and fingerprints all over the upholstery, said the leak was fixed! Before I could get the car back for them to fix the damage they did, the driver's side rear floor was soaked again UNDER the floor mat. The VW dealership in Macon, GA - BUTLER VW - has had the car for almost 3 months again and still hasn't fixed it. My patience is gone! I had to pay the bill for the first so-called repair work and they know it wasn't fixed. They know I'm not going to pay this bill again and they are trying to say the cause is from a different source. I didn't know until now that a $69 million lawsuit had been filed over this same issue or that VW had issued a recall! What do I do now? -

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!! -
my 2000 passat also has leak problem from the sun roof, and now my instrument cluster and my brake lights do not work. -
My car flooded last week and is in the shop. The control modules were flooded and were not working when I took it in. Yet to be verified where the leak is but the water was behind the glove box area, may be clogged drain there an/or the sun roof which may also have been leaking. -
