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 solved the problem - at least for me. I have a 2018 A5 which was working just fine with my iPhone X but disconnects regularly with my xS Max.


Until - just the other day - I tried a genuine Apple lightning cable. And voila, problem is solved. I am suddenly having no issues at all, can run as many apps as I want. I even tried running Waze and Apple Maps at the same time and it was rock solid.


I have generally used high quality third-party cables (usually Anker) and have rarely had issues elsewhere. But all I can say is try the genuine Apple cable and see if it helps. It worked for me.
