Verso rough engine running

I own a 2017 Toyota Verso with a diesel engine. I am experiencing rough engine running, accompanied by the check engine light. Error memory indicates a reset quantity drift compensation issue. Current mileage is 42936 km. I suspect a defective injection valve/injector. Has anyone encountered this?

I had a similar issue with my Verso. Check engine light, rough running... Sounded like compensation adjustment gone haywire. Is your fuel economy also down?

Indeed, fuel economy appears to be affected. What was the eventual resolution in your case? Was it, in fact, the injectors?

Yep, same symptoms. I tried a fuel system reset, but it didn't fix it. Ended up taking it to a workshop. They confirmed it was a faulty injector. Cost me around 500€ to replace it. Worth getting it checked out professionally.

Thank you for confirming my suspicions. I appreciate the insight. I will schedule a visit to the workshop this week. Repair ended up costing 515€.
