1998 Audi A8 Quattro Problems
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.
A fluid leak may develop from the propeller shaft seal on the rear of the transmission. Our technicians tell us that replacing the seal will commonly correct this concern.
Our technicians recommend having the constant velocity (CV) boots and CV joints inspected at each service. Servicing torn CV boots early can prevent the need to replace the CV half shaft or CV joint.
A problem with the torque converter can cause the Check Engine Light to illuminate.

1998 Audi A8 Quattro Reviews
Audi A8 (D2) Years 1997-2003.
This is my second Audi, my first was a 1996 A6. I bought my 98' A8 in 2006, it had 76,000 miles on it, it has 143,XXX on it now. It's been a money pit since day one. Every little thing cost a lot of money. Good mechanic, bad mechanic the car's going to cost you.
Weak links: Transmission. This will set you back $3k-$4.5k depending on where you live and who does the work. Plan on replacing the following: valve covers, head gaskets, oil cooler, breather hoses, engine mounts, tie rods, bushings, head rest motor and the list goes on.
The positives, when its out of the shop, its one of the best cars that I've owned. Comfortable, great handling, nice features. However be aware of the repairs. Unless you're an Audi mechanic, stay away. It's only going to cost you.
