CarPlay Disconnecting - iPhone XS Max

Dear all wise and all knowing Apple Community 🙂

I recently switched from my iPhone 7+ running iOS 12.0 to an iPhone XS Max running iOS 12.0.

I have a 2018 Audi S4 with the latest firmware from Audi.

With the switch to the XS Max, seems that my Apple CarPlay will get into a cycle of disconnecting and reconnecting

every 30 seconds or so.

I tried reverting back to my 7+ and works fine.

1. Siri is enabled.

2. The USB Lockout is turned off on the XS Max. The 7+ had the lockout turned on

but made no difference in the XS Max toggling on or off.

3. Swapped the cables to the one in the box of the iPhone XS Max and USB ports

in the car. This had no impact on the XS Max recycling the connection. The 7+ is uneffected

business as usual.

Not sure if this is tied in with the authentication issue with the charger. I go over wired carplay and the 30

second increment is suspect as that is my lockout time on the phone.

Curious if others are facing this.

Thanks!

I’ve had a case number and a person that I’ve worked directly for a few weeks to no solution.

I don’t have a VPN on my phone and I’m having the disconnect issues. Several of my friends with XS Max iPhones don’t have VPNs either and they’re allvhavijg disconnect issues too.

I'm not having the same luck with the USB meter. Is it plug and play...or do I need to enable something?

I can confirm that not all USB meters are created equal. I just purchased the above as the one I purchased didn't seem to help much.

Same issue on my 2018 A5 coupe. I found a post in here about disabling Sreen Time in the setting of the phone. I’m trying in a few, I hope it works. It’s quite annoying.

Apple isn't here so they can't acknowledge anything. Call AppleCare and Audi.

Any provisional solution proposed in this thread is 100% functional?? I’m really desperate ..

Beta 12.1.3 did not fix my problem. I really start to hate Carplay and I am starting to look for alternatives now.

Thanks for reporting your solution. Looks like CarPlay with iPhone XS/XR doesn't like wifi, whether car based or land based, and also not VPN over cellular.
