Happy to help, and welcome to the forums. There is plenty of info here and extremely knowledgeable people, lot smarter than me. Also, there is a network of friendly vendors, so you don't have to rely on the dealer for parts.
These vendors offer the same or better quality parts at a much better cost: Cascade German, TuneMyEuro, MetalMan, IDParts and others (sorry to the rest if I forget).
Keep curious and reading, these cars can go for a very long time and miles, but better to be on top of issues before they become unsumountable.
Your CKRA engine code car, is a NMS (New Mid-size Sedan) body, it has a timing belt that needs changing every 130k miles with a new water pump, all rollers, and tensioner (and serpentine belt). Belt failure destroys at least the head.
I don't want to scare you, but your car has a few potential issues, in no particular order:
* weak turbo that can fail
* heater core that can get plugged (my 2015 too)
* High Pressure Fuel Pump (HPFP) that can fail. Same for my 2015, and all Common Rail (CR) VW engines with a Bosch CP4 HPFP
