Clone BMW MEV17.2.2 DME and Read ISN with Yanhua ACDP

 Question: 

Have a damaged MEV17.2.2 DME for a Mini Cooper. Possible to clone the DME with Yanhua Mini ACDP2? Bought a used DME with the same Bosch number and DME number.  also for key programming ISN reading by bench/adapter?

 

Here is the clue.

Part 1: Clone BMW MEV17.2.2 DME

You cannot read and write data to clone this DME. It will not overwrite OTP sector.  This ECU has an OTP area.

If doing this way, ACDP will give error “DME communication failed”.

You have to replace DME ECU to clone the DME. Perform “Read/Write CAS ISN to replace DME” function.
Need to disassemble DME and do it in boot mode to clone this DME.

Check the connection diagram and follow instructions in ACDP.

 

Part 2: Read MEV17.2.2 DME ISN Code

Yanhua ACDP will read ISN code for key programming by adapter without problem.

With jumper adapters in module 3.

In BMW DME ISN function, select Read N18 (MEVD1722) DME ISN function.

Check the connection diagram.

Step 1: Prepare ACDP, PCAN-II cable and DME.

Step 2: Check connection pinout.

Step 3: Short the jumper cap to the “CAN-R” position.

Step 4:  Connect the ACDP, PCAN-II cable and DME.

Then read DME ISN code.
