Wireless CarPlay not working iPhone 13

Car is a 2022 Superb.

Really struggling to get wireless CarPlay working on my wife’s iPhone 13 and I’m almost at a loss, the dealership were hopeless and didn’t even bother to update the MIB.  Wireless CarPlay worked fine for ages and then the update 17.6.2 came and it started getting flakey in the iPhone 13.  I assumed it was the car because my iPhone 12 on a lower software worked ok.  I’ve since updated to the latest iOS and mine works fine in the car.  Both phones work fine in our other car (Jaguar iPace) and worked fine on a BMW iX we had for a while.  Note, plugging the cable in on the iPhone 13 works fine.
 

iPhone 13 has been completely disconnected including forget the vehicle under CarPlay menu and Bluetooth and on the MIB as well.

iPhone has been completely reset and is now in the latest iOS version 

The car is also on the latest version thanks to this thead below
