Purpose
Desktop utility for reading and decoding the immobiliser ISN from BMW engine control units (DME/DDE) and related modules. Works from full flash or EEPROM dumps to display the ISN and assist with DME–EGS–EME synchronisation on supported E, F and G series units.

Highlights

• ISN extraction from legacy Siemens/Bosch DMEs: MS42, MS45.x, MSV70, MSV80/MSD80/81/85, ME9/ME9.2 and EDC16 where supported
• F/G-series coverage across EDC17/MEVD17xx families (e.g., MEVD172/172Y/1725, B38/B48/X63TU) plus MDG1/MG1 generation with helper read modes
• Reads from FULL FLASH or from EEPROM depending on ECU family; quick Copy function for workflow notes
• EGS/EME assist to view and copy paired ISN blocks for drivetrain matching
• Simple offline operation from programmer-saved BINs; no network required

Package contents

• BMW DME ISN Reader — main application build
• Help/manual with ECU family notes

Note: file names may differ across mirrors. Use the exact items present in your archive when posting checksums.

Compatibility notes
Function availability varies by ECU hardware, MCU and firmware. Newer MDG1/MG1 and some MEVD17 variants can require specific reading methods or adapters. Always verify dump integrity before writing back and confirm module alignment on the vehicle. Availability varies by vehicle and firmware.

Basic usage

• Read the target DME/DDE (and EGS/EME if needed) with your programmer; save verified backups
• Load FULL FLASH or EEPROM as indicated for the ECU family
• Review extracted ISN and, if required, copy values for drivetrain matching procedures
• Save notes and keep original files unchanged; proceed with OEM-level syncing using your preferred tool

Operating systems
Windows 7, Windows 8, Windows 10, Windows 11 — x86 and x64

Minimum system requirements
Dual-core CPU, 2 GB RAM, 50 MB free storage, standard display, local administrator rights; USB connectivity for your external programmer if required
