Audi 100 Quattro Problems

Engine Oil leak From Valley Pan Gasket and/or Head Gasket

An External oil leak may develop from the valley pan gasket (under the intake manifold) and/or the head gasket.

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.

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.
