'25 Macan Turbo - Apple CarPlay connection Issues

[mikestan]

Just recently my Macan turbo began to exhibit connection issues with my iPhone. The issue is limited to the CarPlay feature and not the voice or media functions of the iPhone from the PCM. The behavior applies when the iPhone is connected to the PCM via WIFI, if I connect the phone with the USB-C port the CarPlay works as expected.
Initially my phone would connect wirelessly to the Macan_xxxx_5GHZ network and CarPlay would work for a few minutes after which I would loose functionality as such:
- the apple map would no longer display the roads/POIs, etc. I would only see a blank grid.
- access to email from the iPhone would no longer work
- browser would no longer work
Eventually I would get a message on the phone asking to switch to cellular of continue on WIFI.

I took the following steps:
- remove and add the iPhone from the Device Manager
- reset the PCM to factory setting

It seemed that the issue was resolved momentarily and but the behavior returned shortly to the point where now CarPlay only works when connected via USB-C.

Looking for suggestions before I take it to the dealer. Cheers!
