JonA Posted February 24, 2017 Share Posted February 24, 2017 HI I need to replace a couple of injectors on our 2.0 TDi (170hp) 2007 A3. one injector has the code 03G130073 with a suffix T. looking a round there are a lot (or several ) suffix letters for this same injector number. Are they different or can they be interchanged? eg. some places seems to suggest that T and M suffixs are suitable. is the letter a calibration code, ie something that would need to be entered into the ECU so usable but not a direct swap? regards Quote Link to comment Share on other sites More sharing options...
