Right.
Tonight I’ve taken every fuse out to check and they are all ok.
Headlight removed to get to the ABS unit so I could unplug the cable, check and refit. I took out the ecu from the base of the windscreen, unplugged everything and refitted. The 30a fuses were also checked. The only one I haven’t done is the transmission module behind the glovebox which I will tomorrow.
As far as I could see everything looks clean and dry - brand new looking.
I’ve stuck the ctek on it until tomorrow when I’ll rescan it and run it again.
Anyone got any other ideas…
