Got a bit of a problem with my 166, the screen washers are awful.
From my experiences with other Italian cars, I'd say that the non-return valves are shot. e-learn only shows how to remove the pump or the jets themselves. ePER shows 2 non-return valves on the parts diagram but no location information.
Has anyone found where the valves are located?
And is it just me or is the automatic spray the screen then wipe feature truly annoying? I forsee that being bypassed very soon. With the current state of my washers it starts to wipe the screen before you get any water on it.
