Application
This number was fitted to the BMW 335d / 535d / X3 / X5 (M57 engine). Compatibility is decided by the number on your ECU label – 8509036 / 0281016640 – not just by the model and year.
Paid options on request
- EGR OFF,
- DPF OFF – only on cars with a DPF,
- AdBlue OFF – only on cars with an AdBlue system (not every model has one),
- Flaps OFF – swirl flap removal.
Data cloning included
ECU 8509036 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. In-car programming can be done with ISTA+ / ISTA 4, ISTA/P or E-Sys.
Numbers to compare with your label
The sticker of an original BMW ECU shows the BMW number and the Bosch number. On this unit they are:
- BMW number: 8509036 / DDE8509036 / DDE8509036-01
- Bosch number: 0281016640 / 0 281 016 640
Repair of your ECU
We also repair customers’ BMW 3.0 Diesel engine ECUs – including units contaminated with diesel, with no communication or cutting out once the engine is warm. A repaired ECU needs no programming, as it keeps your car’s data. Before sending, contact us and describe the symptoms and DDE fault codes.
