Re: EML on after replacement ECU from Vectra fitted to Zafir
I don't know the codes, I'm just going by what the garage have said (should have asked them really). I don't think they know why it stays lit and so came up with the 3-fan theory. I know if you put a brand new ECU in then all you need is that unit, but if it's taken off another car then you need the transponder and chips to go with it, so there must be some hangover from the previous car I would have thought (but I know nowt about it all).
It's going to my local garage for a service soon so I'll get them to read the codes and see what they are. Or is there some software/leads I can use myself?
