(I did a quick scan of messages, but didn't see posting of this fix, apologies if it is known already.) Note: I haven't tested this yet, but I have hopes. I just had my car in for the first service (1 year, only 7,000 miles.) I brought up about Carplay and the reverse problem. They explained that there were Technical Service Bulletins (TSBs) about it. Here's a copy of what was put on the work order of what they did related to that.

I'll try and check how it is doing over the next few weeks, but wanted to share this, since I know other people have also been frustrated.

CarPlay now works properly for us with iOS 11.3. Which is interesting, because there is nothing in the release notes that suggests any CarPlay fixes.

2018 Allroad Prestige, MMI firmware: 1118
2017 A4 Prestige, MMI firmware: 0918
iPhone 8, iOS 11.3 (15E216)

Interesting. I've def. been having this carplay issue. Downloaded 11.3 and will report back tomorrow if this update resolved the issue. Fingers crossed.

So sorry it isn't helping.
What iPhone model, what Audi model/year, and what MMI firmware version? It might help others to know...

My dealer upgraded the MMI firmware to 1180 or something. My complaint was of a intermittent CarPlay freeze. No TSB

In case this helps others diagnose this issue further...

iOS 11.3 on my iPhone X fixed the "CarPlay-disconnects-after-Audi-camera-screen-appears" issues on my 2017 A4 allroad Prestige (MMI 0918).

A few months ago, I took my car to the dealer with the same complaint posted at the top of this thread. At that time, my dealer reported that there is no TSB on this issue, or any MMI firmware update designed to fix this issue. They also were unable to reproduce the issue using their own iPhones; it was only happening for them with my iPhone X. I don't know what iPhones or iOS version they tested with.

I just did a test with my iPhone X & 2017 Allroad with nav... and iOS 11.3 seems to have fixed the CarPlay issue!

11.3 update seems to have fixed iPhone X with carplay issue when going into Reverse to Drive for me - 17 A4 allroad PP.

I'm not so lucky; the intermittent problem still exists.
