I have a 2008 Duratorq tdci 2.4 100ps high top Transit, which I'm currently driving around Europe. I'm mainly taking the scenic route, but if I take the motorway and drive over 100km/h for a sustained period, the engine management light comes on. If I then drive on minor roads for a day or two, the light turns off again. Any ideas?
I took it to a national chain garage to have the fault codes read - they said their code reader can't read English fault codes...
Cheers
