Not as far as I know, and certainly nothing in the handbook or that I've ever read here.Is there a way of adjusting how much spray is used? It seems that most goes to the headlights when I'd have expected most to go to the windscreen.

To avoid guzzling through the washer tank too quickly when my lights are quite clean enough, I switch to sidelights at (say) traffic lights, and wash the screen then. I realise that isn't much help on the motorway, but you get the idea?
