Do a tune up, hopefully it is running synthetic oil, change if frequently.
With VWs, you have to fix the problems as they appear, otherwise the car will go to crap. It takes love and dedication to own a Volkswagen.
Try to use OEM parts as replacement, trust me they are better (except water pumps with plastic impellers). Look out for the plastic parts in the cooling, and vacuum system, as they become brittle over time and will need replacing soon, so don't go selling your car once they start breaking, eventually you'll just have all new ones

.
Good luck, and welcome to the VW ownership, hopefully you'll become a proud owner.
