Just to resurect this old(ish) thread, my driveshaft went on mt 2006 1.9 90Bhp ANU Sharan. The part number on the gearbox end is 02N409345A and the intermediate driveshaft is : 02n409356j I've found the first part on Ebay germany but am finding the shaft very hard to find. I'll post again if I have any success :huh:
I did this job on my VW Sharan (same car different badge) and washed the buttons out. 'How To' here: http://www.vwaudiforum.co.uk/forum/showthread.php?150684-Clean-sticky-Air-Con-Buttons Hope this helps someone.
