Hi
where to begin this car came to us from another garage with multiple codes and a severe misfire on inspection found ecu swimming in water dried out ecu and misfire disapeared and codes cleared took car for a long road test no problem informed customer it would be best to send ecu for testing at extra cost customer wanted the vehicle back and any problems he would return 4 weeks later car returns in limp mode with the above code which was one of the original codes checked pedal position sensor in live data all appeared OK scoped sensor no drop out etc so sent ecu for testing no faults found refitted ecu road tested for 40 miles no fault the went out again limp home and code returned help sorry for long winded approach but all information relative

Hi Richard - had one of these in back in October also with the ECU having a swim in a pool of water/leaves & debris in the scuttle panel. Also with a miss-fire. Checked injectors first and then found the ECU in that state when I went to volt drop the wiring.
Personally I wouldn't put an ECU that has had a soaking and showed signs of water damage back in a car: we had our ECU apart and you could see where the water ingress had accelerated the corrosion on the inside of the casing; also a USB microscope showed damaged tracks on the PCB, which you wouldn't have been able to see easily with the name eye. Game over as far as I am concerned.
We put a new ECU in using Tech 2/MDI and it's been spot on since. I think the new ECU was about £800 from Vauxhall (could be wrong?). Car was a 58 plate and low mileage so didn't mess around with alternatives. You will need the vehicles car pass to put a new one in.
Hope this helps, Barney.

I think you'll find most members of this forum are against having ecu's repaired or even tested as 90% of the time no fault is found but fitting a genuine new ecu has ooften cured the fault.
Maybe speak to Allvox to see if they have a good used/reset ecu.

I've just fitted an ecu to one of these due to previous water damage. The ecu was on back order - in fact Vauxhall had 300 orders on back order. I'm not saying its definitely that but there is clearly an issue with these. You'd do better tossing a coin for an answer rather than ecu testing companies.

We have replaced 4 in the last few months due to water ingress. We still have two on order (Back order) - There was around 1000 on back order across UK & Germany around Christmas time!
We're against sending for repair, but one customer 'googled' the issue & informed me that ECU Testing.com can repair these with water damage. I was sceptical but sent it to them, 1 week later... Too damaged to repair! So the car is still sat in the yard waiting for a nice shiny new one!
