Hello,
I have a 2008 GTi automatic, 3 days ago I began to hear a hissing sound at 2500 RPM, also I felt the car doesn't accelerate as well as before. Yesterday, the engine light went on, and the scanner is showing a P0172 code (System too rich bank 1). What could be the problem?
The car has 100,000 miles, we recently changed the PCV valve and the Turbo Diverter Valve.
