Hi everyone, I am a major newbie when it comes anything ecu related, I'm a mechanic, I can physically fix a car and clear the fault codes and that's about it.

I am looking to EGR OFF my Holden Cruze but I have no idea where to begin. Obviously simply unplugging the vacuum line results in an error code and check engine light which I don't want.

All I know is the car has a Delphi ecu.

Any help is greatly appreciated, thank you so much in advance.
