Audi A3 Problems

Lack of power due to throttle system fault

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.

Check Engine Light and/or Hesitation Due to Failed High Pressure Fuel Pump

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.

Ignition 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.

Driver'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.

Side Air Bags Do Not Deploy Properly

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.

Audi A3 Reviews

My commuter car, great in the winter, decent mileage. I have recently run into the 110k maintenance and the check engine light is coming on and having trouble diagnosing it. 1500 in and still comes on.
Fantastic car, the best looking hatchback out there. Body style is not for everyone, but very functional. The transmission, as many have noted, can be jerky when starting, or during heavy traffic, but boy can it move when opened up. The sport mode holds high RPMs and engages neutral for cornering, quite a thrill on highways. Fantastic lighting package, the dynamic HID's with foglight combo ...
Love the performance and total package, but the warning lights just keep coming and cost $$$. Also had major problems with transmission early on and the car has never been right.
