hello i have a 2006 passat 2.0 tdi , now i want to buy used ecu for test my mods , if i copy flash file from my ecu to used car ecu will my car start ?
or would i need the skc immo keys of both ecu to adapt using ros vcds , even if i copy files ?
other question : Is the instrument cluster immo key the same of ecu immo key ?

Thank you alot for your support .
