2003 Audi A6 ProblemsDigital Display on Instrument Cluster May Fail
The digital display portion of the instrument cluster may fail. Our technicians tell us the entire instrument cluster will need to be replaced to correct this concern.
The 2006-2016 Audi A6 2.0TFSI, 3.0TFSI, 3.2FSI and 4.2FSI 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 A6 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.

2003 Audi A6 RecallsPotential Fuel Leak From Crack at Rollover Valve
The aging of the plastic material in the fuel tank rollover valve, combined with stress from the aluminum ventilation line attached to it, may lead to cracking of the connection nipple. The cracked nipple could leak fuel, increasing the risk of a fire. Dealers will reinforce the nipple on the rollover valve or repair the cracking as necessary. This recall is expected to begin during June 2011. The Audi recall number is 20L8/JY.
