    Ive been reading snippets here and there, and with this bad weather decided Id like to retrofit headlight washers, and eventually I may consider the levelling system too, to go with the oem xenons I have.

    So can somebody link me to wiring diagrams for the system, plumbing diagrams, including any part numbers/photos, and a description of how they opperate.

    From what i undestand they operate on a delay based on time of screen wiping and number of wipe activations. Initialy I am thinking of adding a push switch near the cup holder to activate the washers for ease of install.

    What makes the washer head pop up, is it pressure or a solanoid?

    Has anyone else retrofitted these and i missed the how to guide?
