DDE ECU 8578187 – what to know
BMW number 8578187 and Bosch number 0281030765 identify an original 2.0 Diesel engine ECU. This used unit has not been repaired or contaminated with diesel – we check this by opening the housing for an internal inspection. We then fit it to a test car and check how it runs. Warranty: 6 months.
Services for an extra charge
Before dispatch we can carry out EGR OFF and Flaps OFF (swirl flap removal), and on cars that have these systems also DPF OFF and AdBlue OFF. Keep in mind that not every model has AdBlue.
Does this ECU fit your BMW?
This ECU is used in BMW cars with the 2.0 Diesel engine. The model and year alone are not enough. Compare the label: if it shows 8578187 and 0281030765, it is the same ECU. If in doubt, send us your VIN.
Repair instead of replacement
If your ECU has no communication, cuts out once the engine is warm or has been contaminated with diesel, we can repair it – then it does not need programming. In the BMW 2.0 Diesel, diesel usually leaks from a faulty fuel pressure sensor and reaches the ECU connector through the wiring. Replace this sensor before refitting, or the problem will come back.
