2007 Audi A3 Quattro ProblemsIgnition Coils May Fail
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.
A lack of power may be noted and the Check Engine Light illuminated with various throttle system fault codes stored. Our technicians tell us this is generally caused by electrical connection issues at the throttle body. If this is the case a harness repair kit is available from Audi.
