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.

All numbers are in the BMW engine ECUs category.
