Most reported Audi problems
Fuel quality must be maintained to avoid engine misfire problems; the misfires may cause the Check Engine Light to illuminate.
The Cabriolet convertible top mechanism can fail due to hydraulic fluid leaks. The fluid reservoir is a common failure.
An engine misfire may develop from one or more cylinders resulting in a loss of power and illumination of the Check Engine Light. Our technicians tell us that ignition coil failure is a common cause for this concern. On high mileage vehicles it may be wise to consider replacing all of the ignition coils if one fails to try and avoid future misfire issues on another cylinder.
Problems with air leaks and the fuel injection may cause starting difficulties.
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.
