Thanks. The error appeared suddenly. Yes, the fault code indicates a potential engine management issue. How did you resolve the issue with your Citroen?

My issue was a faulty sensor. But given you suspect chip tuning, it might be more complex. Best to get it checked by a workshop. They can diagnose if the tuning is the root cause and if it messed up the car's original settings.

Appreciate the advice! Took it to a workshop, and the chip tuning was the culprit, causing the engine management system to malfunction. They reset the system and cleared the fault codes. Cost me 180€.

I had a similar problem with my old Citroen C4, though not chip tuning related. Dashboard light came on, and the car felt held back. Did the error appear suddenly, or gradually? Have you checked for specific fault codes using vehicle diagnostics?
