Solved: Yanhua ACDP 2016 BMW G12 750i "Obtain password error"

Problem: When using the YANHUA Mini ACDP to program a 2016 BMW G12 750i for an all keys lost situation, the newly programmed key starts the engine, and the remote control works correctly. However, in the final step - synchronizing the EGS (Electronic Gearbox Control) and EWS (Immobilizer) - the tool shows an error:

"Obtain password error, please contact technical support!"

The system and immobilizer information were read, but the process could not be completed.

Solution
This YANHUA ACDP error often occurs on BMW models with two engine control units. If the EGS password cannot be retrieved, it usually means the incorrect engine control unit data was read.

For BMW vehicles with two engines during an all keys lost procedure, you must read the EEPROM data from the main engine control unit, not the secondary one. Reading data from the wrong unit will result in a password read failure.

Ensure you identify and read the data from the correct ECU to complete the EGS/EWS synchronization.
