I need to replace ECU on my wife POLO SDI 2005year with second hand one.
I have ridden procedure for that job.I understand that I need with special tool read immobilizer PIN,but I don't know how and with which tool I can read new ECU log in pin.That car has IMMO3 system.

Has someone experience with this?
