Vehicle Details:
Make: VAUXHALL, Model: CORSA, Engine Size: 1.3 , Spec: CDTI, Year: 2006 - 2013

Common Faults:
The engine ECU's on Vauxhall Corsa CDTI's between the years 2006 and 2013 are very prone to water damage due to the poor location of the ECU, within the water drain channel under the windscreen. If water builds up within the windscreen drain off this will cause severe water ingress into the unit and will prevent the engine from starting. When scanning the vehicle with fault code readers a host of fault codes may be found including: P1625 - main relay, P0608 - control module, P1120 - pedal position 1 and P1122 - pedal position 2, P0201 - injector 1 voltage, P0202 - injector 2 voltage, P0203 - injector 3 voltage, P0204 - injector 4 voltage, P2146 - capacitor voltage 1 low voltage P1600 replace ECU and P060B - replace ECU. We can rebuild customers own water damaged units or supply replacement remanufactured ECU's when in stock.

Not the first time we've used ECU testing and 100% success rate, unlike one of their large well known competitors with whom we've had a costly and inconvenient 100% failure rate!

Amazing Amazing 5/5

Sent my ecu to this guy's and with in 3 days I got it back plug it strait back in and the car like there was nothing ever wrong with it I will recommend these guys to anyone and every one


Kept updated on what was happening. Once price was agreed got part back very quickly. Once fitted all was good, cured the problem.

Fantastic service. Fantastic service. 5/5

Took 2 weeks and it was flawless. Did have to message as the tracking lacks a lot of information. A part from that great.

ECU water damage refurbishment ECU water damage refurbishment 4/5

My Vauxhall dealer identified the ECU problem but were unable to source a new one for 2 months. As the ECU looked like it had been recovered from the Titanic I was very sceptical that any repair was going to work, however to try and get back mobile I was willing to try. 7 days later and at over half the cost of a new one I received the repaired unit from ECU Testing. The local dealer fitted it and the car fired up 1st time. cracking service!

Excellent service Excellent service 5/5

My ECU was fixed and returned to me quickly, as stated on web site. I was kept informed of the progress of my repair and staff were very efficient and friendly.

Refused elsewhere! Refused elsewhere! 5/5

I tried a couple of places before finding ECUTESTING and was told because i had opened the ecu they wouldn't be able to repair the unit. I mailed ECUTESTING and they told me send it to us if we can repair it we will. I am so happy now i have received the ecu back plugged it back in and Hey Presto fully working car. Took a little longer than advertised but i don't mind because the car is now working. Many thanks to all the staff at ECUTESTING.
