After a drive up the motorway today when I parked up I noticed fairly rapid dripping from the front valance from the engine bay just under where the fog light is. It was not teaming out but it was a good drip drip drip. I thought it may be the pipe that feeds the headlight washer, so I topped up the washer bottle drove home. No water lost from the water bottle... Checked coolant level this hasn't moved either. I am baffled... Any ideas?
