Some of them were there before the ECU problem but I was not confident enough to experiment with VCDS.
When I did a scan at the weekend there were a lot of errors that I put down to low voltage etc. so I tried to clear them. The auto clear did not change anything so from your earlier post I tried one controler at a time and most of them cleared. I was then left with the four.
This afternoon I did another autoscan and that is the scan I posted last.
I'll concentrate on your last comments and try to work through it.
After that I will try Ross Tech support as per your suggestion.
