Audi A3 Problems
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.

Audi A3 Recalls
Under extreme driving conditions, fuel can leak from the fuel tank vent valve. The internal spring may be too weak to hold the valve closed. Any fuel leak increases the risk of a fire. Dealers will replace the affected valve with an improved design. The recall is expected to begin by November 16, 2009. The Audi recall number is 20Q3/J3.
Connectors for a temperature sensor inside the direct shift gearbox (DSG) transmission may have been insufficiently crimped. They could incorrectly read a high transmission oil temperature, and abruptly shift into neutral. The shift position indicator in the instrument panel would begin to flash and the "Depress Brake Pedal" indicator light will be illuminated to alert the driver to apply the brakes. The abrupt shift could lead to a crash. Volkswagen and Audi dealers will reprogram the transmission control module (TCM) with updated software. The recall began October 20, 2009. The Volkswagen recall number is 37E3/S7 and the Audi recall number is 37E5/J7.
Faulty side curtain airbag inflator modules may have been installed in 48 vehicles. In the event of a crash, these airbags may not deploy as designed, increasing the risk of injury to seat occupants. Dealers will replace the side curtain airbags to correct this concern. This recall is expected to begin on August 31, 2006. The Audi recall number is JP.

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 ...
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.
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.
