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.

2006 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.

2006 Audi S4 Reviews
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!
