Aluminium Roof Rails

[gavs]

Hi all Audi owners,

I am currently working on a project that involves Thule and the Audi-esque roof rails, currently seen on the Q7, Q5, A3, S3, A4 Avant.

What I would like to know is a) has anyone removed one
b) has anyone got one, or 2
c) how is mounted to the roof

If any of you Audi owners can help, please let me know.

Ta,
Gav
