Immobilize tune on '12 Passat TDI ECU... CAR WON'T START

[aullein]

Long story short I had an immobilize (hope I worded that correct) done on my ECU (the ability to have it installed in another car). After reinstalling it in both of the cars they will only crank but not start. Can anyone help with this?? Can i just restore the ECU and have that wiped out and start over from scratch??

How this was done via OBD or via Boot mode?

Yes of course it is repairable, Immo delete is no problem. Ecu need to be removed and shipped out to be done on the bench. The virtual eeprom moves around, and also keeps tabs on mileage and calibrations. This will usually kill your warranty when mileages on abs, ecu and cluster don't match.

You will need to edit injector calibration codes into the new immo0 ecu or it won't run optimal, and may fault. I have posted instructions how to to this already and youtube video.
