I know it's been said a thousand times already, but it's always worth checking. Engine compartment fusebox, particurlarly the middle block connector. Water tracks up from a faulty screen washer pump into the fusebox and causes weird intermittant problems. If you have water in the fusebox connectors, you need to change the washer pump (£30), and sometimes the fusebox itself (£60 scrap, £180 new). Associated problems, intermittant ABS lamps, engine temp warnings, airbag, engine faults etc.
