55590156 WJ / MB275800-8136 – Renovated and Clean ECU Engine Controller for Opel Astra H, Zafira B 1.7 CDTI
The 55590156 WJ module, built on the MB275800-8136 board, has been fully refurbished and restored to VIRGIN state. It contains no assigned PIN code or CAR PASS data, allowing it to function as a factory-new controller.
This ECU is designed for Opel Astra H and Zafira B diesel vehicles equipped with the 1.7 CDTI engine, manufactured between 2004–2014. Proper pairing with the vehicle requires diagnostic tools such as Tech-2 or OP-COM.
Each unit has been tested on a diagnostic bench and under real driving conditions. The ECU housing has been refreshed and sealed against moisture, ensuring long-lasting and trouble-free operation.
