Transit fuel filter heater problem

Sounds familiar to an issue I had with my old Peugeot – power loss and rough idling. Have you checked the fuel line connections for corrosion or damage?

Thanks, I'll check the fuel lines. Was it a visual inspection that revealed the problem on your Peugeot, or did you use diagnostic tools?

A bit of both. Visual inspection showed some corrosion, but the garage confirmed it with diagnostics. After fiddling, I took it to a workshop and they sorted it. Probably best to get it checked properly.

Thanks for the advice. Took it to a mechanic, and it was a defective connection on the fuel filter heater. Repair cost was 95€.
