Motorola Rover ECU

Rover 25 / 45 / 75 ECU, MG ZR / ZS ECU 1999 - 2005
This Motorola Rover ECU is a very common failure for late Rover/MG cars.
The fault is normally a non start when the ECU fails - diagnostic tests will show a faulty crank sensor but the fault is normally within the ECU - often the ECU fault is caused by a problem with the wiring to the crank sensor, this wiring fault should be corrected before the ECU is refitted after it has been rebuilt. The other common faults we see are voltage spikes caused by charging the battery with a high power charger or from jump starting. In either case we can normally rebuild your ECU with 2 - 3 days and give a Lifetime Warranty*.
