2014 Audi A6 Problems

Decreased Power and Fuel Economy from Carbon Buildup

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. 

Possible trouble codes include: P0300P0301P0302P0303P0304, P0305, P0306, P0307, P0308

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.

Just an absolutely fantastic car. The technology is superior to Mercedes and Infiniti (both I have owned). Fun to drive. The V-6 engine has a supercharger which puts out an exhilarating ride without any turbo lag.
