While I don't have standard Wireless Carplay or Android Auto in mine, I use a 3rd party adapter, namely Carlinkit 4.0. Out of all the VAG cars that I used with wireless connection (hire or company), the connection was hit and miss. Sometimes working for weeks, then failing multiple times in one journey. With this specific adapter, Android Auto is working most of the time, a quick unplug-replug would solve any issues, Carplay works almost every time. It Carplay framework to get Android Auto working, so even if you use an Android phone, it would show up as Carplay on the car. I don't think it's anything to do with your specific unit, it's just the way the connection works. On my commute, there's a specific bridge that I cross, the music skips every time when I drive over it, Android Auto or Carplay, no matter what but only on wireless.
