Peugeot 607 engine stalls idle

Hi, I have a 2010 Peugeot 607 with a gasoline engine. Recently, the check engine light came on, and the engine sometimes stalls at idle. The error memory indicates an incorrect fuel composition. The car has 92280 km. I've tried fuel additives, but the problem persists. Any ideas before I take it to a mechanic?

Hey, I had a similar issue with my Peugeot 607. Was the error message specifically mentioning a defective cable or plug connection? I had similar symptoms - check engine light and stalling.

Yes, the error message mentions a defective cable or plug connection. Did you also have that specific error? And did it happen suddenly?

Yep, same error and symptoms. In my case, it was a loose connection in the fuel system. I would suggest going to a workshop. The cost of the repair should be around 95€.

Thanks for the info! I took it to the workshop, and you were right – a defective plug connection was the culprit. They fixed it for 95€ as you predicted. Appreciate the help!
