Yanhua ACDP2 Program BMW BDC2 All Key Lost FAQ

Yanhua Mini ACDP/ACDP2 with Module 38 can program BMW BDC2 all keys lost on bench. The

BMW BDC2 Keys Learning Bench Platform is required to work with. Here have collected some frequently asked questions for reference.

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

A: Yes! It needs Module 38 + BDC2 Keys Learning Bench Platform.

Yanhua Module 3 + B48 Interface Board are also required for DME B48 EEPROM data backup.

 

Q2: Can the BDC2 Bench Platform work with other devices except the ACDP host?

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.
