Known Problem

The 2008-2017 Audi S5 3.0TFSI 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. 

Possible engine 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.
