Thanks Gregg -

I don't have any of the codes listed in that thread, nor do I have the engine warnings of reduced power.

I'm down to just 2 sets of codes now after clearing and driving where the iDrive and instrument cluster alerts come and go randomly.

1. ABS / DSC / Brake:
<--------------------------->
Dynamische Stabilitaets Kontrolle / DSC:
- Fault: Wheel-VL
- Code: 006D9B
<--------------------------->
Hand brake / Feststellbremse (EMF):
- Fault: unkown failure
- Code: 006022
- Fault: unkown failure
- Code: 006031
<===========================>

3. Transmission Control:
<--------------------------->
Transmission / Getriebe GS 19:
- ECU OK, no fault code
<--------------------------->
Transmission / Getriebesteuerung:
- Fault: VGSG wheel Notlaufregelung activated. No DXC desired torque setting
- Code: 0055C3
- Fault: CAN message
- Code: 0055C6
