Since no one else actually answered the questions:
1.) Check the records for/ask the dealer if work was ever done on the transmission, if it's a DSG. Ensure fluids have been changed regularly and if the mechatronics unit was replaced. Drive it to ensure it is shifting smoothly. Check reverse for surging.
2.) Check the records for/ask the dealer if work work was ever done on the cam shaft, fuel pump, and cam follower. If these were not replaced, be advised that the extended warranty is 10yrs/120,000mi, whichever comes first. I'd check and change the cam follower immediately regardless.
3.) If it hasn't been done already, the timing belt is coming up for replacement. This is a costly replacement.
4.) Ask about oil consumption. These cars burn increasing amounts of oil as they age. There are lots of reason and lots of fixes. Most of the fixes are band-aids to a larger issue that is costly.
5.) Make sure the aircon works.
6.) Headliners tend to sag. Check it.
7.) MFD, screen between the gauges, had a fading issue. Make sure it's not acting weird.
8.) Listen for squeaks from the starter motor when starting the car.
9.) Check that the doors lock and unlock properly when the keyfob is used. Faulty door latches are common and can cause all manner of strange door lock activity, including but not limited to, the doors not actually locking but the alarm arming.
10.) While idling, listen to the left side of the engine for "crickets." Indicates a faulty idler pully. Could also have a failing water pump. This goes hand in hand with the timing belt. If you're servicing one you might as well do all of them.
