Most reported Audi A3 problems

 

Verified for the Audi A3

2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. Our technicians tell us that whenever the high pressure fuel pump is replaced the camshaft and the follower should be checked for wear. The camshaft lobe pushes on the follower to operate the high pressure fuel pump. Frequent oil changes and use of synthetic oil may help with this wear issue.

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.
