I've just noticed that the o/s/f indicator of my Mk1 Punto is full of condensation. I can't find any cracks and the fitting is still tight so what could have caused this and what do I do about it?
Open bonnet and look for a metal loop behind the indicator. release this and slide the indicator out. Dry it out and replace, if it happens again it has got a hole, you will have to find it.
