It's very believable that people could accidentally be putting gasoline into new TDIs at times. They are being sold to a lot of non-car people who have never owned a diesel, lots of people have multiple cars in the household and that might be the only one that takes diesel fuel. Plus the diesel hose is on the same pump as the gas hoses these days at most stations. All it would take is to be on a phone call while you're fueling-up and bingo!...wrong fuel.

FWIW, traditionally all diesels have had FPs that were lubed by the fuel. That is nothing new. My question is whether a one-time mis-fuel, (putting gas in and driving), could ruin a pump if the gas was diluted in mostly diesel. If it was a strong concentration of gas, the car would die and have to be towed somewhere to be completely drained, at the very least.
