Kadjar injector fault

I'm having issues with my 2015 Renault Kadjar diesel. It's got 126703 km on the clock. Recently, the engine's been running rough, and the check engine light keeps popping on. I pulled the error codes, and it's showing a 'reset quantity drift compensation' error which points towards a potentially defective injector. Has anyone else experienced this? Any thoughts before I start tearing things apart?

I had a similar issue with my 2017 Opel Insignia. Check engine light, rough running, the whole shebang. Did you check the car sensors, especially the airflow sensors? Sometimes it's the simple things that cause these kinds of problems. What does your onboard diagnostics say?

Thanks for the quick reply! I did check the airflow sensor, seemed okay but I'll double check. When you say 'onboard diagnostics', are you referring to the error codes specifically, or is there something else I should be looking at?

I meant the error codes, but also live data if you can access it. See if the values from the injectors are within the normal range. Honestly, in my case, it was the injector itself. After a lot of back and forth, I ended up taking it to a workshop. They confirmed it and replaced the injector. Maybe it's worth getting it checked out by a pro?

Appreciate the advice! I think you're right; I'll book it in with a local workshop. Got a quote of 515€ for the injector replacement, so hopefully, that'll sort it. Thanks again for the help!
