2006 Audi A3 ProblemsDecreased Power and Fuel Economy from Carbon Buildup
The 2006 - 2017 Audi A3 2.0FSI, 2.0TFSI, and 3.2FSI direct injection engines are subject to carbon buildup in the intake system which can cause power loss, OBD codes and a check engine light, and a rough idle. In normal engines, the engine is cleaned by the gasoline flowing through the injectors and into the intake system, however, the A3 uses direct injection so gasoline does not flow through common carbon buildup areas.
The solution is to remove the intake manifold and professionally clean the intake manifold, intake ports on the cylinder head, and the intake valves. This may need to be done in as few as 20,000 miles.
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.
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.

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.
