Volkswagen GTI ProblemsDecreased Power and Fuel Economy from Carbon Buildup
The 2006-2016 GTI uses FSI and TSI engines which are subject to carbon buildup causing power loss, check engine light, and a rough idle. In normal vehicles, the engine is cleaned by the gasoline flowing through, however, the GTI 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.
The 2006-2008 Volkswagen GTI with the 2.0L Turbo FSI engine looses power if the turbocharging system has a leak. The most common turbo boost leak is a torn rubber diaphragm on the diverter valve, which is intended to open only if pressure gets too high. Common symptoms are increased turbo noise when letting off of the gas pedal, and power loss.
If there is a turbocharging system leak, the system will need to be inspected, and the defective seals and/or valve will require replacement.
The flywheel for the 2006-2008 Volkswagen GTI is a non-conventional "Dual Mass" flywheel. It is known to make light rattling noise when the engine is cold. If the rattle doesn't go away when the engine warms, the flywheel may have failed.
If the dual mass flywheel has failed, the only solution is to replace the flywheel.
