Hello everyone!
I own a 2017 A3 8V fl quattro with a manual, and I have been experiencing the following issues:
  • Handbrake not auto-releasing with or without the seatbelt buckled, or only 10% of the time.
  • Auto Hold is not releasing the car and stalling it almost every time.
The auto hold feature was a retrofit done by myself and there are currently no DTCs stored in the 03 ABS module, the button itself works, it enables and disables the feature.
The car also came with the factory hill hold assist (holds the car in place for x seconds) that I have not been able to disable but it somehow stopped working not too long ago.

ABS module's information:
Code:
PN: 5Q0614517AG
HW: H62
SW N: 5Q0614517CG
SW V: 0643


Long Coding:
Code:
12 F1 62 A2 24 25 0A 72 4B 78 0F 07 60 C3 28 48 46 24 50 D2 F0 06 14 73 00 62 50 78 84 08 42 00 00 00 00 12 12 12 12 B8 35 35 19 19 32 32 00

I will happily provide any sort of information about the car or the current setup, and I am open to any suggestions that I should try.
