2006 Audi A3 ProblemsCheck Engine Light and Misfires Due to Mechanical 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.
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.
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.
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.

2006 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.
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.
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.
