Thats right but I don't know when this break year was.
It seems t be different on different models.
But for in this case it s for a C20LET engine, and all C20LET's use Motronic 2.7 so they ALL can be read via paper clip.
hmm not to sure then , normal dealer wouldnt do that then if its a diff engine fitted ne ways ???.........has that all started since the engine was replaced ??? maybe that could be ur problem , if its an amber light ur car is fine to drive...if red its not.........
