 Welcome to my nightmare. Vehicle: 2010 Golf TDI, DSG Mileage: less than 5,000 Ownership: four months The initial symptoms: humming sound from the engine, flashing glow plug light, and reduced power. Dealer diagnosis: Destroyed fuel system due to contaminated diesel fuel. The upshot: $11,000 damage NOT COVERED BY WARRANTY. Massachusetts Division of Standards show no other reports of problems from the 4 stations where I had fueled my car. Would not have bought the TDI if I'd know that there was a chance, even a remote one, that during the warranty period and operating the vehicle according to instructions I might incur $11,000 damage that is not covered by the warranty.
