I realized it when switching back and forth between BM3 GTS and BM3 stock TCU, the gear display was still missing in auto mode despite flashing back the BM3 stock TCU software.
They are aware of this issue now, and they are going to update the stock TCU software on their database very soon.

Tried 10 times today, after the first WOT acceleration, the gear level display dissapeared ( Manual mode ) and no response from the shifter/ paddles.
Fault code:
