Hallo @ all, i retrofitet the BCM from a T6 into a T5 GP.

I changed
- 7H0 937 090 B BCM PQ25 Max4 H74 0712
to
- 7E0 937 090 C BCM PQ25 Max4 H82 0752

Everything is working whell, but the "instrument lighting" is fading in and out when enabled, the Time for the fading can be adjusted by the Light-Intensity-Switch.

Here is the info from the BCM:
