DDE ECU 8582553 – what to know
BMW number 8582553 and Bosch number 0281031303 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.
How to check compatibility
This number was fitted to BMW cars with the 2.0 Diesel engine. The safest way is to compare labels – number 8582553 and Bosch number 0281031303 must be the same as on your ECU. A different number means a different version. If in doubt, send us your VIN.
Would you rather repair your ECU?
We also repair BMW 2.0 Diesel ECUs – contaminated with diesel, with no communication, and those that stop the engine once it is warm. The advantage of a repair is that a repaired ECU needs no programming. Diesel usually escapes from a leaking fuel pressure sensor and travels along the wiring to the ECU connector, so replace that sensor before refitting. We explain the details in our articles BMW ECU contaminated with diesel and BMW N47 / B47 ECU faults.
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.
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.
