China Bosch M7.9.7 / M7.9.7+ / ME7.9.7 / M7.8 / ME7.8.8 IMMO OFF Module for MDflasher (Module 49)
MDflasher Module 49 is a specialized software solution designed for fast and safe IMMO OFF (immobilizer bypass/disable) operations on Chinese market vehicles equipped with Bosch ECUs. The module operates directly as a file editor, enabling technicians to disable the immobilizer system for diagnostics, ECU testing, engine swaps, and troubleshooting faulty immobilizer modules.
To activate the module you need a USB dongle MDflasher. When ordering, please indicate the Serial Number of the key.
The patch is applied directly to the Full Flash dump. The software handles all checksum recalculations automatically, eliminating the risk of bricking the ECU due to incorrect CRC
