Problem:
Attempted a VAG DQ500 (OBH) gearbox mileage correction using a Yanhua Mini ACDP2 and module 30. The process failed—the ACDP app reported a gearbox communication error. Furthermore, the module voltage dropped rapidly despite using an external power supply.
Here is the clue.
ACDP detects that the gearbox hardware number is 0BH927711C.
Hardware version 711C and boot version 401 are locked.
It is not supported by Yanhua ACDP or other tools.
