2009 Audi A3 Problems

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.

Engine may not start due to faulty fuel pressure sensor

A no start condition may occur with a fuel pressure sensor fault code is stored in the powertrain control module (PCM). This problem is commonly caused by a faulty fuel pressure sensor which should be replaced.

2009 Audi A3 Recalls

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.

Potential Fuel Leak During Extreme Driving Conditions

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.

Automatic Transmission Shifts Into Neutral Without Warning

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.
