1990 Audi 100 Problems

Inspect CV Boots and Joints at Each Service

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.

Abnormal Noise From Suspension

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.

Starting problems due to air leaks and fuel injection

Problems with air leaks and the fuel injection may cause starting difficulties.
