Movano Mixture Preparation Error

My 2012 Renault Movano diesel is showing a mixture preparation error. Mileage is at 209901 km. I'm getting reduced engine power, check engine light, rough running, jerking on acceleration, and stalls at idle. I suspect a defective injector. Has anyone seen this?

I had similar symptoms on my Movano. Check your throttle body and air-fuel ratio. Could be running rich.

Did you also experience the stalling at idle? Was it indeed an injector issue, or something else like the oxygen sensor or mass airflow sensor?

Yeah, stalling was a pain. I eventually took it to the workshop. It turned out to be the injection valve.

Cheers. The workshop confirmed an injector issue. It cost me 515€. It runs smoothly now.
