The Engine management light keeps lighting up, I have had the sensors changed and it still happens, it starts with Warning light for light out, (no light out), that may go off and the coolant warning light comes on (coolant level is ok) washer bottle light (water level ok) abs warning (had breaks checked ok) sometimes I can have 3 lights on then they go off, the only warning light that has to be reset each time is the engine management light.

I have been advised to have the electrics looked at, however, they are expensive and can not gaurantee they can fix the fault and still charge you. Any ideas what is causing the fault.
