Immo off Siemens EMS3155: Renault, Dacia and Nissan vehicles
The Siemens/Continental EMS3155 ECU is widely used in modern Renault, Dacia and Nissan petrol engines, particularly in turbocharged 1.2 TCe and 1.6 TCe variants. This ECU integrates immobilizer functionality, meaning a locked EMS3155 unit can render the vehicle undrivable if key synchronization fails or if the ECU is replaced.
Ourimmo off solution for EMS3155 disables the immobilizer directly in the ECU’s firmware, enabling the vehicle to start without immobilizer authorization. This is ideal for second-hand ECU installations, engine swaps, or off-road configurations.
