I think P2262 is the mechanical failure of the turbo. It was curtains when I got that code. Craig

The code I got was really close to that and whatever it was, said it was mechanical failure. I had read enough about the VGT‘s to know I wasn’t going to waste any money on them and later on I took it apart and the scraper ring wore a groove in the vane hub and that’s where it was hanging up.
