New DSG 4motion owner with some questions

[stansnuts]

Hi, just bought a 2016 36,000 mile Highline Kombi DSG 4 motion with what I think is the 204 engine.
I’ve noticed there’s no Adblue filler under the fuel filler, so excuse my ignorance but is my engine an Eu5 or Eu6?
Also I think it has what I see referred to as “big brakes”?
Am I correct in thinking with the big brakes the smallest diameter wheel that’s fits is a 17 inch?

It's a Euro5, if you have no adblue. Correct with bigger brakes, minimum wheel size is 17"
