2008 Audi A6 ProblemsDecreased Power and Fuel Economy from Carbon Buildup
The 2006-2016 Audi A6 2.0TFSI, 3.0TFSI, 3.2FSI and 4.2FSI is subject to carbon buildup inside the engine causing power loss, check engine light, and a rough idle. In normal vehicles, the engine is cleaned by the gasoline flowing through, however, these cars use direct injection so gasoline is rerouted away from common carbon buildup areas.
