2007 Volkswagen GTI ProblemsDecreased Power and Fuel Economy from Carbon Buildup
The 2006-2016 GTI uses FSI and TSI direct injection engines. These 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, since the GTI 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.
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.

2007 Volkswagen GTI RecallsVolkswagen Recalls Certain 2006–2010 Models Due to a Possible Fuel Leak
Volkswagen is recalling certain 2007–2009 Jetta, Jetta Sportwagon, Golf, and Rabbit, as well as 2006–2010 Beetle and Beetle Convertible vehicles equipped with a 2.5L gasoline engine due to a possibly damaged fuel supply line. Under hood fasteners may chafe against the fuel supply line, resulting in a fuel leak. Fuel leakage, in the presence of an ignition source, could result in a fire. Dealers will perform vehicle-appropriate inspections and repairs in order to protect the fuel supply line from chafing damage.
The caps to disable the headlight aiming screws may be installed in the incorrect positions. The cap for the horizontal aiming screw may have been installed on the vertical aiming screw. Improperly aimed headlights could cause reduced road visibility, increasing the risk of a crash. Dealers will install and remove disabling caps as necessary to assure they are in their correct locations. This recall is expected to begin on October 31, 2007. The Volkswagen recall number is Q8.
