All the 2018 VW Tiguan’s have this feature except base model (S) that uses a key in ignition. It works quite well.
If you want to cancel it (every time you turn on car) you click button around the gear shifter that looks like an (A) symbol.
Personally I really like the feature in my wife’s Tiguan and it does save a bit of fuel in start stop and weather is decent out (not too hot or cold because it disables itself then to keep AC or heat going).
