Before I go ahead and break something else.  Wondered if anyone had a picture (from a manual or something) of how to remove the washer jets on a 6N2.  My driver's side one is partially blocked.

 

What's the best way to clean them?  Soak them in vinegar or something?

Here's the info on removing & adjusting the jets 6N2 windscreen washer system spray jets.doc Depending on how blocked it is and what's blocking it, you might find you can dislodge it with a pin if not Vinegar might dissolve any limescale or you could try kettle de-scaler, if not buy a new one 6E0 955 985 A or C Non heated, 6E0 955 986 A OR C Heated 

Awesome nige - I will check the document out.  I'm pretty sure they're not heated on my model.  If they're adjustable I'm not sure but all will become clear I'm sure.
