We had a radiator fan replaced in S. France, which took the garage there nearly 2 weeks. But the engine alarm light remained almost permanently on for the 1,000km back and since. My local garage replaced various things, accelerator rheostat, glow plugs, diesel preheater plugs, still it remained on, but the van was getting worse, becoming almost undrivable. They've finally found that the wiring loom in the engine compartment is a total mess from rodent damage. The say they cannot find a nest in the van. It's being fixed right now, but I'm wondering where the rodent came from. We parked in our son's field in France while we stayed there. He had mice in the house presumably because the neighbour's field was being harvested whilst we were there. Or it could have been in the garage there, or the garage here, or indeed our drive. I doubt it would have stayed that long. I haven't checked the insides or the van yet, of course there is food aboard, so that's the first place to check. This is a campervan, not a large MH. What a drag!
