Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.

    While I was driving one day, I felt something drip down my leg. Upon closer inspection, it was a stream of water coming out of the lower left section of the dashboard right next to a bunch of wires. It had been raining quite a bit. I took it into the dealership and they identified the problem, a clogged sun roof drain. First, that is a huge design flaw. Why would you route backed-up water to just above the dash with no exit route except into the dash? Makes no sense at all. Second, if Audi knows that's a frequent problem, and I don't know why they wouldn't, why isn't drain inspection/clearing included as routine maintenance and especially when it can cause some major electrical damage when it does happen? The dealership is trying to tell me it won't be an issue, which doesn't seem to be the case after reading all of these comments.

    water leak behind driver seat, caused an electrical problem with my car. it is not an inexpensive problem. I took it to audi and this is what they told me. There are three moduals that control the electricity in my car, the convience modual (is the one that has been damaged and allows me to roll down the windows and sunroof and pop the trunk and gas cap and turns on the interior lights of the car)...all of which i cannot use now due to this interior water damage that has caused this expensive problem. its about 1300 to replace the modual.

    After a fairly significant rainstorm, my Audi had water throughout the interior with more water leaking in on the floor of the front passenger area (all windows and sunroof closed tight). When the car was started, it initially started operating only to stall and no longer go into gear. After it was towed to dealer, they could not figure out what was happening. After I did some online research and reported the drain clog issue that so many people have apparently experienced, the dealer then acknowledged the issue of the drain and said that perhaps the water had damaged the transmission module . . . after another day, dealer reported yes that the drain was clogged, the transmission module was fried and they would now fix the drain, replace all interior carpet and the transmission module for a mere $4,800. Since we bought the car used (1 month ago) and a fairly low value, we just got liability insurance so unless I can get Audi to do the repairs free for a know defect, we are out more than we paid for the car to do the suggested repair. Has anyone out there found success in getting Audi to fix the damages caused by this known defect?

    I had this problem a few months ago after I left my car in the garage for a few months. Had to replace it.

    In the last few days when I leave for work in the morning the brakes are as hard as a roc,they will not go down at all so needless to say the brakes do not work when they do that but after awhile it will go back to normal,very frustrating and scary.
