Peugeot 4007 rough running and injector compensation error

Alright, Peugeot 4007 (2007 diesel) is giving me fits! 190k on the clock and getting rough engine running, check engine light, and an error code related to 'reset quantity drift compensation'. I suspect a dodgy injector. Anyone seen this before?

Sounds familiar! Had similar grief with my old Saab 9-3. Compensation adjustment errors are a pain. Is it constantly rough, or just at certain revs? Did you try cleaning the MAF sensor? That fixed it once for me!

Interesting about the MAF sensor! No, haven't tried cleaning it yet. It's mostly rough at idle and low revs, gets a bit better as I accelerate. So, this compensation adjustment thing... is that a job for a regular mechanic, or specialist territory?

Yeah, that sounds injector-ish to me. The MAF was a long shot. Regarding the adjustment, you might get away with a forced reset with the right diagnostic tool, but honestly, with those symptoms, a garage with injector testing gear is your best bet. I ended up chasing my tail for weeks before biting the bullet!

Cheers, I feared as much. Took it to the local garage, they confirmed a defective injector. 515€ lighter now but the 4007 is running like a champ again!
