Being a fellow Parts Advisor myself, just finished a stint with Landrover, now onto SEAT as of monday morning, I quite like a day off!
Heres the part number of what you need: 1K0201160BG
Will come complete with pipe and fixing connections + o-ring.
I've only assumed your vehicle details as being roughly 07 year, so it may differ, but highly doubt they'd have changed them.
Edit*
+ upon further inspection of later years, yep, thats the one you need, unless that part no is superseded, which i cant see that unless I'm physically at work.
