As sad as this sounds, I dropped the little securing nut for one of the windscreen washers into the bonnet while I was trying to put the squirty thing back on, I can hear it rattling around but bugger me if I can get it out of there!
Does anyone have one lying around? Or know of something I can use as a substitute? It looks rank as sticking up out of the bonnet with only the hose to hold it down ha ha.
