How to match this number
We do not give a list of models, because matching is based only on the label. Look at the sticker of your old module and compare: 0281034809 and 8472702 must agree. Do not confuse it with DDE 8474730 / 0281035188 – that is a different unit. We will help verify it if you send a picture of the label and your chassis number via ECUSale contact.
Cloning or programming?
Do you have access to a workshop with BMW ISTA/P or ISTA 4 software? Then the ECU will be coded directly in the car. If not, send us your current module: we will copy its data onto the unit you bought at no additional cost. There is one condition – the memory of the old ECU must be readable.
Modifications and repairs
On request, for a fee: EGR OFF, DPF OFF, AdBlue OFF, Flaps OFF (DPF and AdBlue only on a car equipped with them). Would you rather repair your own module? See the guide to repairing BMW N47/B47 ECUs and the article about a BMW ECU that fuel got into. Full range: engine ECUs for BMW.
