Here is the fault code pulled from VCDS

Sorry for the late reply.
I think you have CANBUS problem. In general, yes, our canbus decoder is erratic, but what you have there is too much.
Please disconnect the canbus bypass and check if all the connection is rigid. In few posts earlier there was a case that CANBUS bypass pin was maligned.
Just having conductivity is not sufficient but visually clearly inspect the bypass sockets.
It may be a good idea to check your parking brake controller 8K0 907 801 E is good.
We sold about 300 units so far, and only 3~4 had the parking brake related issue.
If I were your technician, I'd verify CANBUS line that the parking brake is tapping on as well as the PBC and do conductivity test.
As B8 and B8.5 are getting older, there are so many troubles coming on, for example, for my 2010,
the parking guideline died all of the sudden like few others and at the same time my driver front, and rear door lock actuators died.
Well, rear door lock actuator was bizarre for a long time, but two days ago parking guideline died, and the front driver door lock actuator died.
I also will continue to investigate further on this issue, but we should consider that the car itself could have some problems developing.
