I'm not sure about DAB being standard, as some others have posted about DAB being absent when they got thir cars. There seems to be a move to Internet Radio, but again I'm not sure if that is standard and if it uses the built-in VW SIM for the internet feed or if you have to provide your own internet connection.DAB will be standard I'm sure
When I bought my car in 2019, the Winter Pack (comprising heated front seats, heated windscreen washer jets and low washer fluid warning light) was standard on the R-Line and optional on other trim levels, so that essentially meant the heated seats were 'standard' on the R-Line as they were part of the Winter Pack but they were not available as a stand-alone option or fitted as standard by themselves on any trim level.the question of heated front seats is a weird one. The configurator says that the "R-Line" has them as standard, but they are part of the "winter pack" on the R.
I haven't checked the details in today's configurator, so that may have changed over the past 3 years.
