did anyone try to check the new versions of both ECUs and if VR19 has actually affected it?
VCDS:

0117 is the version of A/C compressor sub:
Subsystem 2 - Part No SW: 9J1 816 797 B HW: 9J1 816 797 B
Component: J842 EKK es33 H05 0117

and it was 0116 before the big update last year.

cannot find an ECU called "battery sensor"...
