Twingo diesel rough running

Hi, I have a 2014 Renault Twingo diesel with 181165 km on the clock. It's started running rough. Having trouble starting, fuel consumption seems higher, and the engine seems to have lost power. It idles unevenly and sometimes stalls. Could the injection be the problem?

Sounds like a familiar problem. I had similar symptoms with my old Peugeot 308. Engine was stuttering and fuel consumption went through the roof. Turned out it was a dirty injector. Have you checked for error codes? That might point you in the right direction.

No, I haven't checked for error codes yet. Is it urgent? Can the dirt lead to engine damage?

It's always best to get it checked as soon as you can. While a bit of dirt itself may not immediately wreck the engine, the uneven fuel delivery caused by a clogged injector can lead to bigger problems down the line, like cylinder damage. I'd recommend visiting a workshop to have the injection system inspected.

Ok, thanks for the info. I took it to the workshop. Indeed it was the nozzle, it was dirty and also a little broken. 515€ later it runs great again.
