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: P0300 , P0301 , P0302 , P0303 , P0304 , 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.

A problem with the torque converter can cause the Check Engine Light to illuminate

Premature wear in various multi-link suspension components can cause noises that are difficult to diagnose. Worn suspension parts can also cause uneven tire wear and create steering alignment problems.

2008 Audi A4 No Start after Refueling and Popping Noise from Trunk
Popping sounds from the rear of the vehicle may be heard moments after starting the engine, or when slowing to a stop. This noise is from the leak detection pump filling the fuel tank with air, and releasing to retest the system when it finds a fault. The sequence of faults identifying this issue are as follows:

Succession of loud pops from rear of vehicle
Pops go away, and fuel economy decreases
Check engine light illuminates
OBD trouble code P2404 and/or P0441 is stored
Engine will not start after refueling (must crank for over 30 seconds)
Vibration when slowing to a stop
The cause is a valve which is mounted on the front of the intake manifold, commonly called the N80 valve, or EVAP system purge valve. The valve is designed to open under specific circumstances, but a worn valve will remain open at all times, preventing the pressurization of the fuel tank.

Correction of the issue is to replace the N80 valve with the latest revision.

2008 Audi A4 Turbo Pressure Diverter Valve Diaphragm Torn
The Audi A4 2.0T FSI engine looses power if the turbocharging system has a leak. The most common turbo boost leak is a torn rubber diaphragm on the diverter valve, which is intended to open only if pressure gets too high. Common symptoms are increased turbo noise when letting off of the gas pedal, power loss, and engine code P0234 .

If there is a turbocharging system leak, the system will need to be inspected, and the defective seals and/or valve will require replacement.

2008 Audi A4 Dual Mass Flywheel Failure
The flywheel for the 2006-2008 Audi A4 2.0L Turbo is a non-conventional "Dual Mass" flywheel. It is known to make light rattling noise when the engine is cold, and should subside once the engine temperature raises. If the rattle doesn't go away when the engine warms, the flywheel may have failed.

If the dual mass flywheel has failed, the only solution is to replace the flywheel.
