I have an (55), car registered in September 2005. though the vin shows it as an 06 model. Volume buttons are on the left, MFD controls on the right. The buttons are the same as Reds. So...when did the buttons change to this type? on the 06 Model? Purely out of geeky interest you understand....

clive, you state your car is a 06, does the vin code have a 5 or 6 in the 10th place?....I think its the 10th place, if my old memory serves me. Or have we established that your mfsw was retrofitted? check inside your service booklet theres a load of codes in there, you should have one that states (1MS) this translates in vw code terms to "leather steering wheel with Tiptronic" and as far as I can ascertain this means if you have that code on your page then your car was factory built with MFSW.
