As above, gearbox every 38k if S-Tronic. If the haldex hasn't been done then get it booked into an independent specialist (so they can clean the filter as well as Audi don't clean the filter, just change the oil), then check how long ago the brake fluid was done and possibly get that done as well. Aircon is only required if its not performing as it should.
You could maybe do spark plugs if you wanted but unsure if they're due at 40k or 60k.
