Would you rather repair your own ECU?
Has your BMW 3.0 Diesel ECU been contaminated with diesel, lost communication or started cutting out once the engine is warm? We can repair it. The advantage of repair is that your car’s data stays in the unit, so it does not need programming. Before you send it, write to us with the symptoms and the DDE fault codes.
Does this ECU fit your BMW?
This number was fitted to the BMW E60 / E61 / X5 E70 / X6 E71 (M57 engine). The model and year alone are not enough. Compare the label: if it shows 8510841 and 0281017021, it is the same ECU.
