I have just done a delivery in Milton Keynes, pulling onto Standing Way (A421 iirc) I noticed my truck seemed to be pulling really really well, they always seem to pull well after you have lost the 27ton load that you were pulling previously tbh, but this was very different.
The engine note seemed wrong, I had an emission warning light on and the truck was throwing out clouds of black soot - unburnt fuel?
I pulled over, switched off, restarted and it seems happy again, no light, no more smoke etc etc.
I just wonder what would cause such a thing? any ideas?
I want to put in a defect report when I get back to the depot, but am a bit puzzled what to put - no decent fault description, the fitters won't touch it.
Probably just some random EDC - electronic diesel control - issue. Electronics screwing up I imagine...
perhaps it re-mapped itself briefly?
Anybody?
