2010 Audi A4 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 inspection of the cam and high pressure fuel pump can prevent cam failure.

Decreased Power and Fuel Economy from Carbon Buildup

The 2006-2017 Audi A4 uses the 2.0FSI, 2.0TFSI, and 3.2FSI direct injection engines. These 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 A4 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. 

Various Probelms Caused by Clogged Plenum Tray Drain

Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.
