A couple of months ago, I had a problem where the electrics stopped working for a day, and then they seemed to sort themselves out.   The only problem now is when I put the handbrake on, the oil light lights up instead of the brake (!) light on the dashboard.   Is this a 'computer' problem ?  Would it cost much to get it sorted ?   Doesn't seem to be causing any problems at the moment, more of an annoyance !   Think the car is on it's last legs, as hatchback struts have gone on the boot, exhaust rattles (but may just need tightening)   Cheers, Andrew
