17's will fit fine, as above but 16's probably won't clear the brakes.
17's are a good size to source second hand as people sell them cheaply when upgrading to 18" wheels and there are a huge amount of VW group wheels that will fit.
Assuming a 7.5" wheel, keep offset a lower number than 50 and higher than 40 and try and go for a fairly flat spoke to clear the callipers as they're quite big.
Also pay attention to the style of the wheel as you don't really want to be scrubbing a complex spoked pattern with a toothbrush whilst squatting in a puddle when the outside temp is around zero degrees. Been there, done that and don't recommend it!
