I am sorry I might have missed it but did they say the fuel was contaminated and the HPFP failure is still covered under the extended emission warranty?
At first the service rep said he couldn’t rule out bad fuel, but in the end they said it was a bad hpfp that caused my issue. The dealer said it was a rubbery/plastic substance in my fuel, but their paperwork said it was metal shavings. I’m thinking the dealer tried to down play it to me I guess. Either way, VWoA had them replace the hpfp, fuel filter, and they cleaned my diesel tank because it was contaminated with something from the hpfp. This was all covered under warranty.
The fuel I used had nothing to do with this issue in the end.
My car was finished today for the melted sensor, but I can’t get it till Monday. I’m going to assume this will be covered under warranty since I was specifically told by the dealer this had to do with the emissions. I’ll find out Monday though.
