Polo 6R: Upgrade BCM Help

[polobyte]

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?

Anyone?

[iichel]

Probably... But not enough information to be sure

[polobyte]

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?

[iichel]

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.

Is there any schematics on net?

[iichel]

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