Window washers S3

[sleam]

Hi! I just broke the washer nipple on my S3! Oops indeed as I'd just installed a new washer pump and decided to see if the nozzle was aiming in the right direction. It was but now it's in my tool box. The plastic broke. I see that I can order replacement parts but my question is how do you get to the mechanism/ line etc behind the body? I can't work it out. No rush as I have to order the piece but any suggestions since the books simply say remove and replace.

Afraid you have to take the dash apart...

damn, that's what I was thinking! Sigh.
