Peugeot 3008 rough running engine
Summary of the thread
A 2019 Peugeot 3008 diesel was experiencing rough engine running and a check engine light, with a diagnostic code indicating a "Reset quantity drift compensation" error. The suspected cause was a defective injector. After checking airflow sensors and considering onboard diagnostics, it was confirmed by a workshop that the issue was indeed a defective injector, which was then repaired.

Thanks for the reply. I haven't done any specific compensation adjustments via onboard diagnostics. I'm not sure which parameters to check. Can you provide a bit more detail? Fuel consumption has been pretty normal, it only started recently.

Okay, if the consumption is normal and the error persists, plus you have rough running, it does seem injector-related. I'd say at this point, because you're not sure about diagnostic procedures, getting it checked professionally might save you money in the long run.

Thanks for confirming my suspicions. I took it to a workshop. It was indeed a defective injector. Repair cost was 515€. At least it is sorted now.

Drift compensation? Sounds like it's struggling to balance the fuel trims. Have you tried any onboard diagnostics or compensation adjustments? Maybe that's worth a try before jumping to injectors. Has the fuel consumption changed lately?
