Thanks, what worries me about going to a main Subie dealer is they'll want serious money for what is a bum wire if only I can trace it. .   Mark D. Yes rather like your  story ,  I really suspect it is simply  a poor  electrical  connection somewhere. Daz-RSK  Wow, thanks I'll have a look at the fuse box and see if I can identify the wires you speak of.I notice that the drop down flap of the fuse box has fixed on the inside a numerical light panel about 2 cms widex  3 cms long.... I was wondering what this was for ... is it another built in code reader?
