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.

Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.

2005 Audi S4 Reviews
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.
