Koleos rough running engine light

Hey, I'm having a weird issue with my 2023 Renault Koleos diesel. It's got about 228k km on it. The engine's running rough, and the check engine light keeps popping on. I scanned it, and it's throwing a "Reset quantity drift compensation" error. From what I've gathered, it could be a dodgy injector. Has anyone else run into this?

Whoa, that sounds familiar! I've got a Koleos too, and I had almost the exact same symptoms last year. Rough running, engine light, the works. Though I didn't get that specific error code. I also suspected that the injection valve/injector was defective.

Interesting! Was the injection valve/injector indeed defective? And did you have to do anything special to fix it? Any idea what the 'reset quantity drift compensation' actually means?

I never figured out what the error code meant. But yeah, it turned out to be a faulty injector. I took it to a workshop, they replaced the injector and charged me 515€. The problem went away after that. I'd say get yours checked out!

Thanks for the info! I was hoping it wouldn't be an injector, but it seems like that's the likely culprit. I'll get it booked in at the workshop and hopefully, it'll be sorted soon. Thanks again!
