Count me in as another one who hasn't had a diesel-related story in ages. Things happen, but they're not TDI-related. I don't think anyone's asked about my car or mileage or anything like that in 7-8 years now.
I did have a particularly frustrating experience at the gas station the other day that was only tangentially related to diesel, because one of the two diesel pumps at the station had a dead card reader, so I went through the whole "enter Plenti number, try to swipe card, fail, try again, fail again, put fuel cap back on, drive to the other pump, try again" hassle.
