Those that have bought new cars, are you still driving your TDI? I am worried about it sitting long term. I bought a new car yesterday and hope to have my car turned in December or January by the latest. For a December turn in I only have around 130 miles and I need around 50 to get to the dealer. I was going to drive it twice a week to take my son to school so the car does not sit and will start when I turn it back it. Should twice a week be sufficient?
