Hello guys,
I bought new BCM for my Polo 6R, when I connect it to car, VCDS can’t read it. New BCM is 7E0937090C.
Do I need to do some wiring or?

This new BCM is from Transporter 5.5.
Current BCM that is in car is 6R0937088F.
Is there anything else that you need to know?

yes you need to re-wire all of you canbus (instrument cluster, powertrain, OBD, LIN generator) to the BCM and remove the external gateway. perhaps a wire from T73b/4 to the dimmer T6/3.

I don't know, best is to get some schematics of 088F and 7E0 BCM max for yourself and compare.
