1999 Audi A6 Quattro from North America - Comments

To the person with the undercarriage rattle:

"18th Sep 2007, 18:44

I just bought a 99 a6 2.8 quattro with about 94000 miles, has anyone had any rattling noise from the under carriage? I recently replaced my cv joints to eliminate the clicking noise from the turns, however the rattling noise from the under carriage remains. I don't even have to hit a hard bump the smallest pot hole creates the most annoying rattle... someone help me out please. BTW even a certified mechanic cannot find anything loose when he inspected it."

Check the driveshaft bushings - I had the same problem with my '99 A6 Quattro and a rebuilt driveshaft is what it took to cure it.

My girlfriend has a 99 A6 Quattro, and aside from the windshield washer fluid container cracking, the tie rods going, tires bubblin, mirror tint being possessed, engine fan blade cracking off, lubricant for the suspension, and electrical issues with the alarm, locks, seat position memorization... huff (using my inhaler) the newest addition of insane list of car problems is the back right flooring is collecting what seems to be gallons of water.

Can anyone please inform me of what this problem is related to, and how to solve it?

I'm mystified how people report hooking their bumper onto curbs (3 x no less) think this is the cars fault. Better yet, sliding through an intersection because of ice and probably driving too fast and getting into an accident. Sorry...that's not the cars fault.

My '97 A6 quattro Avant has 112K and tows a 17' boat during the summer months. Awesome car.

Again, bubbling tires are not the cars fault. In regards to the water in the rear, if it has a sunroof, check the drainage tubes. Usually they can get clogged with "stuff" over time and need to be cleaned. I've heard a long piece of electrical wire is the best tool.

Another possibility is the seal on the rear door adjacent to the foot well that fills up. It could be torn.

One thing I've found to be it's weight in gold is have an independent shop on your speed dial to take care of any auto repairs. The dealer (s) aren't usually the better choice.
