Newton Abbot can indeed help.
I guess as I used to do all this sort of thing with Fiat/Alfa Romeo I was being nosey/trying to cover all bases before I waste a day.
Just wanted to do all I could before I venture up there as I have the kids for half term and didn't want make a wasted trip with two bored, moaning teenagers in tow!
Whoever it was I spoke to knew exactly what was needed and assures me it is all doable other than cutting a blade.
I will have a look at the ECU this afternoon and report back.
