Is it not on top of the RHS wheel arch area, under the bonnet, mounted in a soft rubber mounting - if it is it the petrol fumes purging thing you are referring to, well I seem to remember that is where it is on the 9N Polo and can't think of any good reason why they would move it.
I can't find keys for daughter's Beeza to check, sorry!
Update, 9N Polo 1.4 has it mounted onto the coolant expansion tank.
