Default Communications module issues

'23 Q4 e-tron 11k miles stopped connecting to 1 of our 2 iPhone 16s. At Audi dealer now with a pending $229 diagnosis fee, a bit outrageous for evaluation of a failed essential part under warranty to be evaluated. Tech tried several reboots and it still won't connect to primary user's Audi account. Even tried suggestions by Audi corporate, so far to no avail.

Stuff like this is why we will never own or lease another Audi vehicle. Never had anything similar in multiple BMWs, Tesla and Volvo.

Most of us have never had a problem with our Audis… which includes our ‘23 Q4 50…

Totally agree but consumer time has value, not just dealer time. Audi - never again!

I don’t blame you for venting… I only believed your vent needed balance…

Audi software is very flakey and unintuitive. I've experienced too many issues to mention on 2024 q4 Etron 55 software. Intermittent LTE offline, Sos, down, navigation down. Charging setting via app, offline. But I do love the way it drives and put up with the niggling software problem. Btw, having only one user profile that talks to the main Audi servers seems to have addressed the disconnection issues. Make sure the second driver user profile is added as a local user, so setting are stored in the car, and not in the cloud Audi server. Seems to have minimized the LTE fails lately.

Yes… the Q4 e-tron seems overly sensitive to poor cellular signals. For example, we can only connect here at home if we back into its usual spot…

I know it's most likely a different module but the dealer replaced my entertainment module (2024 Q4 e-tron 50 quattro) without me specifically asking for it. I had been experiencing MMI erasing all my stored favorite stations on a regular basis from day one of ownership. When I had contacted Audi corporate, they promised a software update coming in 4Q of 2024 would fix the issue. That software update never happened, but I mentioned the issue again at my 20K service and that's when my service advisor said that my entertainment module was throwing all kinds of error codes and they will be replacing it under warranty. It took a few days for the part to come in before Christmas but they put me in a Q6 e-tron quattro loaner in the meantime, so I was happy. I haven't had the issue since they replaced that module. Maybe I was lucky but not all Audi dealers are shady.
