I think the problem has been solved...
The warning alarm wouldn't turn off... but there was no faults.. (well, the horn was the fault)
We traced all the wires back from the control box to the engine yesterday and the brown and blue wire (i think that was the colour) wasn't properly clipped into whatever it was meant to be...
when we plugged it back together it all worked fine again
Now i just need to use her... she hasnt moved in about 2 weeks
Cheers for the help chaps!
