This engine ECU is a very common failure for the Vauxhall Corsa/Combo 1.3 CDTi built from 2006 – 2013, the failure of the ECU is caused by water ingress due to the poor location of the ECU within the water drain channel under the windscreen.
We can rebuild customers own water damaged units or supply replacement remanufactured ECU’s when in stock.
Because the common fault with this ECU is water damage we see a wide range of symptoms caused by ECU failure, the most common symptoms are:
Misfire on one cylinder
Will not rev past 1500 rpm
Non start intermittently
Complete non start and no communication via diagnostic.
Common customer reported fault description:
“Initially the car started to misfire/run rough and the engine management light would come on. Called out a mobile mechanic who came out and performed a diagnostic check and the fault code read injector number 4 faulty. When he came to change the injector the car would not start so he investigated further and found the ECU submerged in water”
