Peugeot 107, 2010 diesel, 265k km. Check engine light, stalls at idle, error about incorrect fuel composition. Suspect a bad connection somewhere. Anyone seen this?

I had a similar issue with my 107. Is the error message specifically mentioning fuel contamination or mixture issues? I had engine stalls too. Check the cable and plug connections to the fuel system components. It could be a simple fix.

Yeah, that's the error. Fuel composition. Which connections, specifically? There are quite a few...

For me, it was the connection to the fuel pressure sensor, but I'd advise a workshop visit to properly diagnose where the defective cable or plug connection is located. I had the same symptoms, and it turned out to be a corroded pin. It cost me 95€ in the end.

Thanks. Appreciate the heads-up. Will get it checked at a workshop.
