2012 Volkswagen Tiguan ProblemsDecreased Power and Fuel Economy from Carbon Buildup
The Volkswagen Tiguan uses the TSI direct injection engine. This engine is 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, since the Tiguan uses direct injection, 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.
