As a data point my 2018 Audi A4 just got a map update (2017-2018 update) about one month ago. I was able to download it from the myAudiConnect site, put it on an SD card and install it. Audi now includes the first three years (one every 6 months) of updates with the car purchase. Audi, MB and BMW now jointly own HERE maps and they supply the Audi maps. I would assume they also provide the VW maps.
