Meh. Until Scott stops getting misfires and EPC warning lights from his DTUK box, I'll leave it
The burning question is will this flag a TD1? If it does I'll give this a miss.
I'm sure everyone would love to hear the official response from Revo tooAs long as it's re-flashed back to the very same identical file that your car (or production batch) had, the checksum will be the same, so no TD1 flag will be raised.
If it's inadvertently flashed back to a file which your car did not leave the factory with, it will not match what Audi AG have, then a TD1 flag will be raised.
