Some clarification required

I have the Xenons with the washers. The washers activate by pulling the wiper stalk forward. But if I try to use it again it refuses to, even after 30 mins.

Is this normal? Is there a time period between being able to utilize the washers?

 

I have them on my 2004 R53. The wiper stalk maneuver you describe provides a momentary operation of the windshield wiper and as I recall, they are designed to wash the headlights only every 3rd occasion or something like that.

 

You are correct, it works in conjunction with windscreen washers.

But when you try again only the windscreen washers goes off. Very strange.

 

IIRC it goes off every so many time the windshield nozzles go. For example, every 5 times you wash the window it washes the headlights, or something similar to that.
