delete apple music playlists from car

I believe the option you are seeing on your car called "vestas music" is your personal radio station in Apple Music based on the songs you have downloaded or liked. You can tell Siri to "Play Music that I like" and she will start playing that station. You can also say "I don't like this song" or "I like this song" to tailor the music more specifically to what you like. Also if you continually skip a song, Siri will learn that you would rather not want to listen to that one.

Every Apple Music subscriber gets their own personal radio station. I don't have CarPlay in my BMW, but do use Bluetooth to play Apple Music through the car, so your iDrive screen would look different than mine.

To find you personalize radio station on your phone, go to the Music app and select the "For You" tab. I find mine under the Recently Played section and yours is probably called "vestas music". It does a great job of playing music I like based on what I have listened to before. Once in a while it will play something the I would rather not listen to and I just tell Siri "I don't like this song", and it will not play it again and will further target songs that I may like instead.

I wish my BMW X1 had CarPlay, but I bought it 1 year too soon. I have no problems listening to Apple Music over Bluethooth, I just have to select the music from my phone to play wirelessly instead of being able to use the touch screen.

The playlists that show up on your BMW are pulled from your iPhone. You cannot delete them from your BMW using the controls that manage iDrive, it can only be done from your phone.
