Peugeot 3008 rough running engine

Hi, I'm experiencing an issue with my 2019 Peugeot 3008 diesel. The engine is running rough, and the check engine light is on. I pulled the codes, and it's showing a "Reset quantity drift compensation" error. The car has 219333 km on the clock. Anyone else encountered this? I suspect a defective injector but would appreciate any insights before I start replacing parts. I have checked the airflow sensors.

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?

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.
