98 1.6 Oil pressure switch - Mookfish
The oil light on the dashboard no longer lights up, not that big a deal as I allways though that if you waited for it to light up the engine was as good as dead anyway.

I thought that it is either a duff bulb or a bad conection to the sensor, trouble being that I can't find the sensor and can't figure out were it is from the haynes manual either anyone know?

Never thought I'd need help with something this simple, but with the amount of electronics on modern cars I'm finding it hard to find things now.

AFAIR it's down the back of the engine; about half way along.
