C2 Diesel Fuel Filter Heater Issue

I had similar symptoms with my C2. Have you checked the fuel filter heater and its connections? A faulty connection there could cause these issues.

Thanks for the tip! Where exactly should I be looking? I'm not very mechanically inclined, so any pointers would be appreciated.

The fuel filter heater is part of the fuel filter housing. Given your lack of experience, I'd advise you have a workshop check the cable and plug connection there. It was the culprit in my case.

Thanks! That was the issue indeed! Took it to the workshop, they said the cable to the fuel filter heater was defective. Cost me 95€ to get it sorted. I appreciate the help!
