There are 2 ways to read S63 DME ISN: via OBD or Bench mode by dismantling the DME.

If you dismantle the DME to read, it is okay too, but it will take you a little bit more time.

OBD Mode Read/Write ISN

If you use extra N20 Bench Integrated Interface Board, it can read 100% successfully

And ACDP APP comes with the wiring diagram which shows how to exactly connect N20 interface board to ACDP.
