Engine Controller SID801 5WS40025DT 9644860380 – Citroen Berlingo / Peugeot Partner 2.0 HDI IMMO OFF Plug & Play
The offered SID801 5WS40025DT engine controller is an original control module used in Citroen and Peugeot vehicles with 2.0 HDI engines. The unit has been prepared in the IMMO OFF version, which means it does not require immobiliser programming or adaptation in the vehicle. After installation, the controller operates in Plug & Play mode, which means the vehicle can be started directly without additional diagnostic procedures.
Each SID801 engine controller offered in our range is previously tested on a diagnostic test bench. The module undergoes full verification of diagnostic communication, power supply and injector control system operation. Thanks to this, the customer receives a fully functional component prepared for installation in the vehicle.
The unit has been prepared as IMMO OFF, therefore it does not require coding, synchronisation with the BSI or key programming. This solution is particularly useful in the case of immobiliser failure, BSI damage or communication problems between vehicle modules.
