DDE ECU 8578185 – what to know
BMW number 8578185 and Bosch number 0281030762 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.
Extra services (paid)
On request we carry out EGR OFF, DPF OFF, AdBlue OFF and swirl flap removal (Flaps OFF). DPF OFF and AdBlue OFF only on cars fitted with these systems – not every model has AdBlue.
Application
This ECU is used in BMW cars with the 2.0 Diesel engine. Compatibility is decided by the number on your ECU label – 8578185 / 0281030762 – not just by the model and year. If in doubt, send us your VIN.
How to get the ECU working in your BMW
- Option 1: programming the ECU in the car.
- Option 2: cloning the data from your old ECU (immobiliser, ISN, VIN) – included in the price.
- For cloning, send us your old unit and we transfer the data to the ECU you bought.
Diesel in the ECU – the most common fault
- Cause: a leaking fuel pressure sensor – diesel travels through the wiring to the ECU connector and destroys the electronics.
- We repair ECUs contaminated with diesel, with no communication and those that cut out when the engine is warm.
- After repair, the ECU needs no programming.
- Replace the leaking sensor before refitting, or the fault will return.
