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.
