I think Ive found out why the fault code check it's working!
The fuse for "engine control" has blown. I've got a feeling it will blow again if I replace it because it had a 15 amp fuse in it instead of a 10 amp fuse so looks like somebody has put a higher rating fuse in to try to stop it blowing fuses.
I noticed half the fuses in the car are the wrong rating, there were a few 15 amp fuses where there should be 10 amp fuses
