Engine Belts And Pulleys problems of the 2011 Volkswagen Golf

On the night of August 5 about 8:30pm, while driving at 45mph, my car lost power while driving. I was able to get out of the traffic flow and coast until I could get to a side road and then pushed it into a parking lot. I looked at the engine and saw the serpentine belt was damaged. I also noticed fuel sitting on top of surfaces in the engine compartment. I asked my son to verify if he smelled fuel which he did as I have little sense of smell. After seeing the damaged serpentine belt, I did not attempt to restart the engine. I had the vehicle towed. At the dealer, the service representative attempted to try to start the vehicle and move it and said it wouldn'¿¿t start, possibly causing additional damage since the serpentine belt was shredded. After some investigation the dealer'¿¿s service manager explained that their leading theory is that diesel fuel leaked from fuel filter gasket onto the serpentine belt. Then the shredded serpentine belt took out the timing belt and caused the engine to rotate out of time causing internal damage. Car had been maintained per manufacturer schedule by this dealer, and this failure occurred 6k miles after most recent service. Dealer was unsure why the diesel fuel leaked, but the high pressure fuel pump and fuel filter seemed viable problem points. After getting engine parts replaced at great expense and getting the engine running on Aug 30, 2014, dealer indicated that they couldn'¿¿t detect a fuel leak and said serpentine belt condition showed no condition to indicate failure but failed anyway causing the cavalcade of engine damage. Many parts were replaced or removed and reinstalled during the repair, so it is questionable that there was no fuel leak.
