I have a Astra 2004 Mark 4 (I Think) 1.7 CDTI SXi and I cant seem to find the ecu.
The reason I am trying to find the ECU is I would like to add cruise control and want to carry out the check's from the guide in the technical section.
My ECU is not in the same place as the one in the guide and was wondering if anyone could help. I am imagining it should be easy to get at in order to run checks etc.
Any help much appreciated.
