i have been having wiper issues with this car for about 5 months now...it is getting ridiculous. things have been fine for the last few weeks however i seem to be getting a water leak coming from under the dash. when going through car washes/heavy rain i am getting some leaking. lately the wipers have not been working. they start and then stop...and maybe move a few inches then stop again. I know it is not the motor or anything like that. i have it narrowed down to the comfort control computer or hopefully just a waterlogged relay. i cant seem to figure out where this relay is!! anyone know where the relay is and how i can access it? i would really appreciate your help..as i would rather not go to the stealership over this! thanks!

I'm having the same issues less the leaking. My wipers were slowing down and then finally stopped. I don't think it's the motor or transmission under the hood, rather I believe it's the wiper relay. I'm trying to find a part number and the location under the dash. If anyone can get that to me I'd appreciate it. If this is the correct part number let me know... 4B0955531E. I see that it is a wiper relay but don't know if it's accurate for the B6.

 

I had the same problem. Hopefully you fixed it by now but I followed the steps here http://forums.audiworld.com/a4gen2/msgs/1110379.phtml and freed my stuck wiper. It seizes pretty bad so be careful not to break the spindle if you hammer it out.
