2011 Citroen C3 cnu fault

Car: Citroen C3
Year: 2011
Variant: 1.2

Categories: Electrics, ECU, Warnings & Lights

I have had to return my car for the 4th time with a Cnu engine fault. The Cnu unit has been sent off to be repaired or replaced with a reconditioned 3 times. Each time I get it back engine management light comes up and ecu fault detected.
Everything has been checked or replaced injectors etc, but still somehow detects a fault. I have been without my car on and off for over 9 weeks now and still careless as it is now back at the garage.
