Immo off solution Siemens VDO MSM 1.3: Mercedes. Fix Start Error
The Siemens VDO MSM 1.3 ECU is used in select Mercedes-Benz petrol models from the late 1990s, such as Mercedes Benz A-Class W168. Its immobiliser system uses transponder handshake logic tied to the vehicle’s DAS (Drive Authorization System). When the handshake fails, ignition and fuel injection are blocked.
CK Decode offers a precise immo off process for the MSM 1.3: it patches the transponder sync, disables starter-lock logic, and corrects checksums—ensuring the engine can run standalone, without requiring the original key or immobiliser module.
