Audi A3 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.
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.
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.

The timing belt broke sending the Pistons thru the engine. It was inspected by the extended warranty company we have and they agreed it had to be replaced. They pay 3,500 leaving us to cover the rest so can someone help us know if 5,100 is a fair deal? Thank u.

Audi A3 RecallsDriver's Frontal Air Bag Inflator Ruptures And Sprays Metal Fragments
The driver's frontal air bag inflator may deploy the air bag with excessive pressure, resulting in the inflator rupturing and causing metal debris to be sprayed onto vehicle occupants. Dealers will replace the driver's frontal air bag inflator free of charge to resolve the concern.
The side air bags mounted inside the front seats may not deploy properly, as the seat covers are not stitched properly to allow them to freely deploy. Dealers will replace the driver's and/or passenger's front seat back covers free of charge as needed to resolve the concern.
The vehicle may fail to start, or stall while driving, due to a faulty fuel pump. The dealer will replace the fuel pump to resolve the concern.
