The Yanhua ACDP Module 3 BMW ISN Module allows reading and writing BM.W DME ISN codes via OBD or bench mode, including all-key-lost cases. It supports N20, N55, N13, and other models without opening the DME shell where possible.

Why Choose Our BMW ISN Module?

1. OBD & Bench Support – Read/write ISN via OBD for N20/N55/N13/N16/N18 and MSV80/MSD85 DMEs; bench mode required for other models.

2. Compatibility – Works with E, F, R, and M series, covering listed diesel (N47/N57) and petrol engines.

3. No Soldering for Supported Models – OBD access avoids DME disassembly for compatible units.

4. Key Programming Support – Functions with CAS, FEM, and BDC systems as described.
