My second service is up soon at around 39,000 miles so I was wondering if the DSG oil change is usually part of it or wether I need to specifically request it and pay for it as well presumably. Starting to sound expensive? I will shop around but what sort of figure will I be looking at? Nothing else wrong and pads are all ok (almost unused!)

Depends how good the dealer is, but I've found that generally the service covers the basics only and anything like gearbox, Haldex, brake fluid etc. are advised afterwards and charged as extras.
