Sorry, yes, there was a good reason I didn’t return to the forum…I sold my A3 shortly after, as a result of not being able to resolve this issue and a few other problems I was having. Main dealer tried multiple times, and recommended I try a third party auto electrician. My suspicion was a weak/broken DAB antenna, as I assumed the GPS signal was also received through that. Or a software issue. Figured the main dealer would have caught both of those issues, though, so I really don’t know. Sorry I can’t be of any help, Dan. It’s put me off of VAG cars completely, after only driving them for 20 odd years.

Nice one. Did you have to have the firmware, or the correct Nav map database reinstalled? Did you get it done with Audi, or an independent garage? Cheers

Can anyone explain the resolution to the Nav initialisation issue in more detail please? I'm having the same issue, where my Nav hangs on 11% initialised, and I'm debating what the best course of action for getting it fixed is. Thanks!

Did anyone find a resolution for the issue with the navigation not loading beyond Initialising? Mine gets stuck on 11% and won't move beyond that initial loading screen.

Gary, did you have any luck with this? I'm also having trouble with Navigation stuck on initialising.

I had this issue when I got my A3 e-tron 2 years ago. Audi said there was an issue with the DAB antenna which was integrated into the rear windscreen. They replaced the rear screen and it's been fine ever since.

Thanks, Cliff. Good shout. I'll dig through and see if I can find anything. Electrickery, indeed. Unfortunately, this vehicle has not been the shining example of an Audi for those very reasons.

New here and want to acknowledge the new members advise of post and run...I'm here and very grateful for the advice, and certainly not looking to splash and dash. I've been having an issue with the Traffic Sign Recognition (TSR) system on my 2020 Audi A3 e-tron (8V). After a few minutes of driving, a warning appears: Traffic Sign Recognition Limited. See owner’s manual for details. When this first happened, the car was still under extended warranty, so I had Audi inspect it. They said my windscreen wasn’t OEM and that the camera bracket was broken slightly, causing the camera to be a little loose. Their theory was that the loose camera might be sending unstable data, confusing the TSR system, or that the non-OEM windscreen might require an ADAS calibration. However, the TSR system still recognises signs; it just reports limited functionality. I also doubt the windscreen is the root cause, since the TSR worked fine when I bought the car in 2023 and the windscreen hasn’t been replaced since. Around the same time, I noticed my navigation system would hang at 11% while loading and never complete/load. I started to suspect the two issues might be related. The TSR system probably uses both the camera and navigation data to confirm speed limits. If it’s only getting input from one source, that could explain the 'Limited' warning. I took it for a diagnostic scan, which reported a low 12V battery and couldn’t complete a full check. Thinking this might be voltage-related, they recommended I replace the battery with a higher-spec one, which I did and coded it to the car, but the issue persists. I also downloaded the latest official Audi map update (0230002C) and verified I had the activation key, but the update won’t install, whether via USB, SD card, or Online. It just says 'No relevant data found on the medium' for USB or SD, or gets to 80% and doesn't complete if updating Online, in the vehicle. At this point, I suspect it’s primarily a navigation system issue. I think I need to fix that first, then if the TSR issue remains, ADAS calibration. If anyone has insights or suggestions, I’d really appreciate it.
