#5 of 10 Could this be my problem
Dec 04, 2010 (5:42 am)
Hello I have a Audi A6 that has leaked inside after a good rain. Under the passenger seat on the back floor passenger side and front floor passenger side. Now just the other day my transmission went in to limp mode and I was told by a technician that ran a dianostic on my car that the comp. said it had a wirring grounding problem of some sort and it would be $90 and hour in labor to pin point the issue to find the problem. What advice do you have for me concerning this issue.

1. If you went to an Audi dealer and he/she told you $90/Hr. I'd wonder if
they really had any training from Audi. To put it another way either they know where the ground wires are located or they don't.
2. The water can come from many different places, here are just a few.
a. Windshield & or rear window seal not sealed properly.
Door alignment Rt./side, window & door seals.
Removing the rear seat lower portion may reveal moisture draining from the rear window down to the foot well area.
b. Drain system in front of the windshield under the engine hood.
c. The (B Post) if you have a four door, between the front and rear door.
d. Pull the Seal belt out on the passenger side, the part that goes in the (B piller) should be dry.
e. Sunroof drain holes blocked, roll the sunroof all the way back check for leafs or other stuff. Try to determine if the water is Rain water or does it have color indicating Oil or Anti-Freeze content.
As for the transmission ECU(Electric Control Unit) you should get a copy of the Error report which that technician performed especially if you paid for it. If it was done using the "VAG/VAS" VCDS Diagnostic program it has critical information regarding
the parts, location and error codes relevant to your Transmission problem.
Then I would take that report to an Audi Dealer for the Transmission problem. If you live in a state which has a Dealer/Automotive repair shop certification program, first check the internet for a Certified Dealer or Repair
shop that specializes in Audi.
Hope this has been of some help. As you see there are many possibilities.

Not sure what years this applies to but there was a successful class action suit against Audi based on this specific problem. The cause of the leak is a clogged passageway blocked by leaves or debris on top on the windshield wiper covers. This forces the water into the car and seeps down under the passenger floor to the transmission computer box. I wasn't aware of the cause and it destroyed my car, wasn't able to drive as well as developing mold. Not only was the computer destroyed but the cable harness as well.
If you caught it early enough, you may be able to get a new computer board. Audi has a fix for the problem in there new maintenance program.

Water can damage the engine and other car parts. Parts such as the chassis can deteriorate extensively.To buy a used car can be risky, when buying a water damaged make sure your valuer guides you well.

Here is a link to one of several " Class Action suits" pertaining to water damage on particular VW & Audi products:

To the original problem poster; The best you can expect from a group action is labor cost reimbursement. Periodic maintenance of drainage systems are generally not performed by dealer service procedures unless you specifically ask that it be done as part of a regular service; Noted on a dealer service work order. Water damage to the chassis is highly unlikely as Audi chassis is a unitized platform, of very specialized legierung ( combined metals) which are highly resistant to rusting. Additionally the chassis parts, after assembly, are completely submerged in sink bath before paint primers are robotically applied, resulting in the 12 year guarantee pertaining to rust. That being the case, and as previously mentioned, used car purchase should always be approached with caution and research. Some U.S states have additional "Consumer Protection Agencies" which can provide additional help should the dealer/Manufacture route fall to to provided help.
The wire and control unit damage of the transmission are residual damage caused by a lack of periodic maintenance on the drainage systems. In closing it should be said the car purchased makes you the owner of the whole car with the exception of Software and related patents, much the same as with computers.
I hope this has been of general help in approaching difficulties.
Perhaps your car insurance might give some additional coverage options depending on policy coverage.
Edmond's resources are many, take a few minutes and browse for specific info which might be of help.
