Audi A3 Problems

Check Engine Light and/or Hesitation Due to Failed High Pressure Fuel Pump

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.

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.

Decreased 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. 

Possible trouble codes include: P0300P0301P0302P0303P0304, P0305, P0306.

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.

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.
