I had two errors when trying to read DME ISN through bench mode using mini acdp and X8 bench interface… and now it does not wanna connect through Bluetooth after I reinstalled the mini acdp app.
Error 1: Device state synchronization failure
Error 2: DME communication error
As for this problem, yanhuaacdp.com engineer offers the corresponding solution as below.
Please select “OBD/CAN Mode Read/Write ISN”-> “Read MEV9N46 DME ISN” or “MEV9N46L DME ISN” to read ISN via wiring connection, no need BMW-DME-ADAPTER X8 interface board.
