Hi all

A very strange problem.

A Workshop has tried to ad ORG. BMW 3AC to a 11/2021 BMW X5 G05.

They have messed up all wires when connecting them, not following the guide from BMW - like doing an IKEA buy.....

Now - all wires is OK, the right Rear Fusebox and MAX LIN-Bus Power module is also installed.

LED on Push button is flashing slowly red and trailer hicht can't fold in?

I've coded the 3AC (AAG module in) E-SYS - whole car is updated with ISTA, all modules Encoded.

Tried other 3AC module - samme issue.

I can fold the hitch in with +12 & GND with no problem.

Can it be 2 bad new modules or what do you think ? 

Error 802832 and 802830
