Regarding the carbon build up, there is a VW fuel additive you should add every 10k miles that VW says will help lessen carbon build up. I pick some up at the dealership with every oil change.
Does VW have a TSB on this or did the dealer just sell you on snake oil?

Fuel additives do next to nothing for intake carbon buildup since the fuel is injected in the cylinder whereas the carbon builds up on the intake valves.
