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.

2004 Audi S4 Problems
A problem with the torque converter can cause the Check Engine Light to illuminate.
Various bushings—located around the subframe, suspension, and steering—deteriorate with age. A clunking noise when driving over bumps, accelerating, or stopping may be a sign of worn bushings.
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.

2004 Audi S4 Reviews
Fab car...my friends call it my rocket! Brake dust accumulates fast on rims...but brakes and handling have already saved me from one sure accident. Engine eats oil (normal!) like gas (1 quart/1000 miles). Strut bearings need a check for wear...hearing noises after 100K mi...
Love the car! Has been proud owner for a year now, had some problems, but thankfully had them taken care of by extended warranty. The most major one was the replacement of the steering rack. So highly recommend getting one from a trusted provider as any labor is expensive on that car. Recently (after 35K miles) replaced brake pads/rotors for front. Came up to $460 (parts, labor and taxes), not too bad. Sine the engine is heavy, the front brakes go out much sooner than rear. I still have 70% left on them.
