Original ECU 8579785 (0281030878)
We sell a used, original DDE 8579785 unit (Bosch 0281030878) for the BMW 2.0 Diesel N47. Before dispatch we look inside it and then test it in a car. The unit has never been repaired and has never been in contact with diesel. The ECU comes with a warranty of 6 months.
Extra modifications
For an extra charge we carry out swirl flap removal (Flaps OFF) and EGR OFF. We do DPF OFF and AdBlue OFF only when the car has these systems – AdBlue is fitted to some models only.
Repair of your ECU
The most common cause of BMW 2.0 Diesel ECU failure is diesel: it leaks from a faulty fuel pressure sensor and travels through the wiring to the ECU connector, destroying the electronics. We repair ECUs contaminated with diesel, with no communication and those that cut out once the engine is warm. A repaired ECU needs no programming. Replace the leaking sensor before refitting, or the problem will return. Read more in our articles BMW ECU contaminated with diesel and BMW N47 / B47 ECU faults.
Data cloning included
ECU 8579785 is used, so it will not work straight after plugging in. It has to be programmed in the car, or the data from your old ECU has to be transferred to it: immobiliser, ISN and VIN. We do the cloning at no extra cost – just send us your current unit.
BMW number and Bosch number
Both numbers on the label matter when you order:
- BMW number: 8579785 / DDE8579785 / DDE8579785-01
- Bosch number: 0281030878 / 0 281 030 878
