As many others on this site, our Audi has started filling up with huge amounts of water when it rains....and dumping it on our feet and out the rear a/c vents etc. The plenum tray is clear....but we have been unable to locate the plug to release the water that is sloshing and gurgling around constantly. We saw a youtube video of an A6 where the owner pulled a plug and tons of water rushed out onto the ground, but we cannot find a plug in our 1999 Audi A8. Please help!

mechanic says $ 3100.

The car has been leaking oil ever since we had it changed. I know that in some cars the plug has a compression seal that's a one time use. Is this the case with the Audi?

Filter is in a permanent housing; not a removable canister. Cap that secures and seals filter in place does not have enough clearance to get past alternator to allow removal of filter.

Can not get anything to blow out of the vent's, It sounds like it's on but nothing comes out

Do you put the refrigerant on the high side or low side. Or can you provide a diagram?


feels is shifting between gears

When I drive 55-60, the steering wheel shakes..not too terribly, but enough to bug me. I got my 2 front tires replaced today (with balance), and it still does it.

2. When i stopped driving and looked under car, I saw a little smoke coming from the center. Should I be concerned?
