1991 Audi V8 Quattro Problems
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.
Oil leaks can develop in the crankcase ventilation hoses, in between the cylinder banks.
A burning smell may develop due to an oil leak form one or both valve cover gaskets. Resealing the valve cover will generally correct this concern. However, the valve covers should be inspected and replaced if damaged.
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.
