Problem overview

The 2006-2008 Volkswagen Eos 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.
