GM 09158670 / Siemens 5WK9153 is an original engine ECU used in Opel vehicles equipped with 1.8 16V petrol engines. The offered model is a newer and improved version that replaced the older and more failure-prone ECU previously installed in a different housing.

The ECU has been redesigned to eliminate common faults found in the earlier version, resulting in improved durability and more stable engine operation.

After installation, standard programming using Tech2 or OP-COM diagnostic equipment together with the vehicle PIN / Car Pass code is required. The process is identical to programming a brand-new ECU from Opel dealership.
Every ECU is fully electronically tested, verified before shipping and covered by warranty. The offered module does not come from flooded or heavily damaged vehicles.
