Are any of the cables to the sensors damaged?

What does it run like at idle? Does the engine look like it misfiring slightly??

it seems fine, sounds as musical as usual, even gets up to full speed on the motorway. so its not in engine lock out. just lacking that initial woooosh!!

I've had this twice now, once in the snow and once after it being washed if that made the difference I don't no??

The power dropped on mine the rev counter stopped working and engine and glow plug lights came on!
After leaving it for abit (a few hours) it darted up fine and then hasn't done it again, took it for a diagnostics and no fault.......?

don't get anything like that. thought it might be a loose wire somewhere, but without some kind of wiring diagram, i'm gonna struggle a bit. will have to get all down into it and trace some wires for damage and breaks!!! any info will be well received!!
