Q1: Yanhua ACDP2 support BMW BDC2 All Keys Lost now? Is it true?

A: Yes, it is compatible with other tools that support BDC2 all keys lost.
Q3: How to read a locked ECU?
A: The DME module is not locked, so no special steps are needed.
Q4: Is reading ISN required?
A: No, but you must back up the engine EEPROM data (Step 1) using Yanhua Module 3 and B48 Interface Board. This data is used for Step 6 (Write DME ISN) and Step 7 (Reset EGS EWS).
Q5: Can’t read with another device? Is it necessary to have all the adapters for each version of the BMW engine to make the first step (backup coding data)?
A: Use Yanhua Module 3 and B48 interface board to read the EEPROM data of DME B48 SPC5777. You also can use other available devices to read the data.
Q6: Do I need extra modules to do Step 7 (Reset EGS EWS)?
A: Only require the Yanhua BMW BDC2 Keys Learning Bench Platform. Then reinstall BDC2 in the car and reflash via OBD after programming.
Q7: Does it also require parts from a donor vehicle the front left and right antennas? What can the antenna do? Is it necessary?
A: No.
The LF Smart Key Antenna & Remote Control Receiver are used for key functionality (intelligence & remote control) testing.
If you don’t have them, just reinstall BDC2 in the vehicle for testing.
