Requirements for playing audio files
Applies to SD memory cards1) and USB storage devices in the FAT16, FAT32, and exFAT file systems.
MP3 files (.mp3) with bit rates of 32 to 320 kbit/s or variable bit rate.
WMA files (.wma) to 9.2 mono/stereo without copy protection.
Playlists in the M3U, PLS, ASX, and WPL formats.
Playlists no larger than 20 KB and with no more than 1,000 entries.
File name and paths no longer than 256 characters.
Alas, it's not clear if this includes WMA lossless. Only one way to find out.
Also, I'm sure VW has different audio/entertainment options available, each with varying file support.
For example, for a 2018 Tiguan, the list of supported file formats is much longer according to this:
