Code and VIN are assigned at the factory, after that you could even change the code to your postal code if you want, you would need to get new transponders though.
Most of the time you can reprogram the VIN with the tech2.
But it doesnt realy matter anyway, immo doesnt care. That only cares if the secret between the immo box and itself is order and if the immo gives the all clear message
Hi everyone, I'm Mitchel and live in Holland
I drive a Opel AstrIgnia from 2003 with a Z20LET engine but also maintain Z22SE engines for friends.
Specialized in electronics and diagnostics for Opel vehicles as a (out of control) hobby
So if anyone has questions, don't hesitate to ask :)...
For getting the EGR off with a Tech2 up the year to 2004 in the VIN (W0L0TGF4825083014 = 2002 W0L0TGF4845083014 = 2004)
Then go through the SPS process as normaly, with the Tech2 make sure you select 2004 or higher, else you get the No Engine Management message.
