They've leaned out the injection cycles a LOT without much detuning when converting the engine from use in a "sports" model to a common model to give it more appeal to the normal person. The reduction in fuel use results in increased combustion temperatures and pistons will burn before anything else (anyone else remember all the blow ups when refuelling was banned during the F1 1.5 litre turbo era in the 1984).
An aftermarket tune probably resolves this problem better than the VW revision.
But why weren't they caught by the service campaign?
