One problem related to alternator/generator/regulator has been reported for the 2007 Volkswagen GTI. The most recently reported issues are listed below.
The mil or check engine light would come on repeatedly. Each time the vehicle was taken to the dealer for the check engine light, the error code was "fuel pressure regulator. " after 5 seperate trips to the dealership for the same issue, the dealership has replaced the high pressure fuel pump, the low pressure fuel pump, the fuel filter, the fuel regulator, the low pressure fuel sensor, and most recently the high pressure fuel sensor. I believe that the high pressure fuel sensor was at fault from the very beginning.
