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!

So I want to report back and say that so far getting this usb power meter and connecting the phone through it to the car has worked wonders. I haven’t had a power based disconnect since using it.

I have had it not want to work when starting the car once. I had to unplug the power meter and plug it back in a few seconds later and it started working again.

Once my phone connects to CarPlay, I don’t have any issues. I think I’ve driven for about 5 total hours since starting it. This solution is ok for a band aid but I expect way better from Audi/apple and I look forward to not needing to use this workaround.

For reference, 2018 Audi Q7/iPhone XSM 512

This is not a paid post, and feel free to check whatever products out that you want, but this is the exact unit I ordered:

Today I was informed by my Audi dealer that there are no new MMI update than my current version 0211...and therefore no fix to this.

The reason that MMI versions can differ between car models is depending on selectable add-on equipment for each car...

I have one more thing to try before leaving IOS to android and that is to plug in a iPhone X model...and see what happens...

You and I have same vehicle—make, model, year—with same MMI and the same phone with same iOS. I don’t have the problem any longer.

Are you using genuine Apple cable? Do other devices work in your two USB ports in center console?

Hi!! I knew how to do it. U have to deleted old your ID on iCloud.

Completely deleted the app. I still used a third party podcast app (Overcast) and had no problems.

Have you reported this with the Feedback tool you have for the beta testing?

Oct 30, 2018 8:38 AM in response to sapper17

Well, I tried the in-line USB voltage meter that another poster suggested and no problems since. I have an XS Max 512GB and 2017 Audit S4 Avant in the UK

Why don't you contact Audi, ask them, and report back here?

Anyone running the beta is under a Non-Disclosure Agreement (NDA) and cannot post their results in a public forum like this.

Everyone needs to be submitting bug reports to Apple here: https://developer.apple.com/bug-reporting/

So it's working better with Apple maps uninstalled and having restarted but not perfect. But now when I plug in my phone I'm getting a notification that the accessory is not supported.

Today I tried CarPlay in a Audi A4 2017 and it worked like a charm.

This car was running MMI version 0333.

I will contact my Audi workshop once again and try to convince them to update my MMI.

Thanks for the prompt reply Carolyn!

Going by the list, the Audi S4 has the same unit as the Audi A4.

Looks like none of the Audi sport variants are listed; they are more of a series/trim range.

A4: A4, S4, RS4

A5: A5, S5, RS5

Thanks for the details! Interesting about the airplane mode. I believe the WiFi is still enabled on iOS 12 when on airplane mode. I disabled the WiFi broadcast on my car too (2018 S4) it makes any difference.

Having a very similar issue. I actually was an apple senior tech support advisor until a few months ago- I now work in the automotive electronics field. Since swapping to the xs max, on ANY in dash unit, old pioneer appradios, any new CarPlay unit, etc, when plugged in, I am able to get audio, but NO video on the dash unit. No CarPlay interface, no controls, nothing. Multiple units. My iPhone X running same iOS 12 works perfectly. Makes it fairly difficult to test CarPlay for customers.

Hmm not sure does seem like a lot of Audi owners on here.

Not sure if the USB on the Audi is drawing too much current. My connector to the USB on both cables I have tried seemed to be a bit warm or might just be coincidence.

So can we 'confirm' that WiFi is not the issue? You have WiFi on but fully deleted Google Maps, right? I will try the same.

Wonder if Google can update the app so it doesn't conflict - perhaps it is an issue with the virtual cockpit having Google maps as well?
