Do you mean you have done a "chip tune"?I just applied a new tune for the car on Wednesday
Yes. I flashed it from a reputable tuner wendesday evening.
"STAGE NONE"!
Sir if I may?
Please post an auto-scan and logs of the PSI sensors and current data of Soot pile up levels?
You should really consider re-flash to stock for a more consistent diagnostic stack.
Given that the tuned flash was applied on Wednesday and DTCs turned up on Friday morning, on a vehicle with very low mileage, I absolutely agree.I would seriously flash to stock first.
