Thanks for the help lads, I did notice a small window on the side of the ECU so maybe i will be able to see flash codes through it.For a change the customer is not in a panic for it so i will have a bit of time on this one.I would like to get is sorted all the same, and not leave it on the long finger(which i might have to get extended soon). I will look through some forums and see if i can find any info or even a video to see it operating. Any more ideas gratefully received.
