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.

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.

Audi S4 Reviews
I have owned my 01 S4 Avant 6 speed for 5 years now. I bought it form the original owner with 120K miles on it with service records. My wife drives it daily and has 205K on it. The car still has original clutch, head gaskets, and turbos. Most repairs have been general maintance, but some repairs are costly. Some parts such as EGT sensors, O2 sensors and center driveshaft carrier bearing failure cost massive amounts of money. Although the timing belt kit wasn't to expensive, it still required 5.5 hrs of my time to install. I have owned every german car from vw to Porsche and our S4 is a top 3 favorite of mine. It is second to none in the snow. The downfalls of the car are keeping tread on the tires (3rd set now), expensive parts, and cluster display window not fully lit. Over all, I'm impressed with the S4 function and reliability and I would by another.
Bought my 2001 S4 new in March 2002. It has 149,000 miles now. It has been an excellent car. It is a 6 speed manual with the original clutch. Wondering how much longer the clutch will last. It does not slip but am thinking it must be getting close to the end of its useful life. Am wondering if I should sell it while it runs well or keep it and eventually replace the clutch. Any advice on this would be helpful.
I had a 2005.5 Audi S4. I really enjoyed driving it until 104,000 miles when the timing chain tensioner went out and audi wanted to replace the engine for $18,000. It was our 4th audi. Never again. Will always drive american from here on out. Could not work with the dealer or Audi. The vehicle was well maintained and even the Audi tech said the motor was in great shape. I returned the audi back to Audi even though I owed $14,000 and paid the dealer $2,300 to remove the motor. Now Audi Financial wants their money.
I purchased my first amazing Audi S4 new in July of 2006. My S4 came with the tiptronic automatic transmission. I drove this excellent car for 148,844 miles. Other than normal maintenance, I had to replace the headlights because of flickering problems at about 100,000 miles, and had to replace all coils at about 95,000 miles. These were the only two major repairs the car sustained. Today, I drove a new white, (the front end looks like a Stormtrooper), 2011 S4 home! I would highly recommend Audi!
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...
