Vehicle Details:

MakeVauxhall ModelCORSA Engine Size:1.3 SpecificationCDTI Year2006 - 2013

Common Faults:

The engine ECU/ECM 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 repair customers own ECM/ECU or supply replacement remanufactured ECU's when in stock. If I purchase this will it cure my fault?

Great service. 5/5

A professional outfit that run an excellent service. I was kept informed all the way through the process. Very pleased with the result especially because they saved me £800 on main dealer prices!

Excellent Service 5/5

Very very good service, was kept informed of the progress all the way through. Would definitely use again and certainly recommend.

Cannot fault service 5/5

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 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

ECU 4/5

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. 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 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 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.
