Whats the problem youve got mate?
Unidentified noise from the engine when under load, even a light load. Extremely bad fuel consumption. Too many active DPF regens. Sometimes another will start about 10 minutes after I have cleared one as described in the manual, but no DPF warning light yet. All present from new.
But no fault codes = no fault. Dealers can't do anything because there are no fault codes. Seat Customer Care and Seat Technical Unit will not accept that anything can possibly be wrong because the ECU has not recorded any fault codes.
