Audi A3 Problems

Rattling From the Transmission May Be Heard When Engine is Cold

The flywheel for the 2006-2008 Audi A3 2.0L Turbo is a non-conventional "Dual Mass" flywheel. It is known to make light rattling noise when the engine is cold, and should subside once the engine temperature raises. If the rattle doesn't go away when the engine warms, the flywheel may have failed.

If the dual mass flywheel has failed, the only solution is to replace the flywheel.

Check Engine Light and Misfires Due to Mechanical Fuel Pump Failure

The engine in the 2006-2008 Audi A3 uses direct injection which requires very high fuel pressure. This high fuel pressure is achieved by using a high pressure mechanical fuel pump (HPFP) that is driven off of the camshaft.

The HPFP may fail due to damage from a defective camshaft. The defect causes abnormal wear of the mechanical barrier between the camshaft and the fuel pump. This barrier, the cam follower, will wear down and cause failure of the camshaft and the HPFP.

Symptoms include illumination of the check engine light, engine running roughly, and loss of power. Engine codes associated may be P0300, P0301, P0302, P0303, P0304, P0087, P1093 and P2293.

To correct this issue one or all of the following will need replacement: the camshaft, high-pressure fuel pump, and/or the cam follower.

To help prevent this issue from occurring, the cam follower should be inspected every 10,000 - 15,000 miles. 

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.

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.
