Assistance Systems Error - Speed Limit Display (warning message)

[W1NGE]

I think I‘ve understood the point.

Apparently, the actual fix is not a firmware fix, it’s just a new version of the data map which seems able to be installed OTA. My guess is that there were a problem with units / mph / kph in the data, or lack of unit/values.
This is my conclusion thanks to Audi Q6 forums.
Is there a way to know the data map version in the PCM (there is in the Q6 MMI)?

Map updates for the PCM will include this stuff and will be OTA - expect these regularly and each are welcomed as the also carrying new EVSE location updates as well.

My turn: assistance system warnings, so no ACC and all that security stuff
The notification asks me to clean the sensors “capteurs encrassés, nettoyer le capteur” but everything is clean.

I’ve tried to reboot (30s volume push), close the car, wait a long time, and so on.
When I start the car, the warnings appear again within 10s. I didn’t try (yet) the factory reset.

Any advices?

I guess the better option is to refer the issue to the dealership.
I did the same, as my Plug & Charge is greyed out on the PCM, and they have referred the matter to Germany, as factory reset the dealership did, did not work. However, no issues like the one you mention (so far)

Clear the cache. Maybe it will help.

Everything is back to normal… I didn’t do anything special…

Interesting…
I had exactly the same problem today after my car being jet washed. Camera, windscreen were all cleaned and dry. I’m not sure what happened.. But everything is back to normal after 1 hr.

I’m seeing the speed limit display warning message, and also now data connectivity in the car to the cellular network.

I didn’t drive the car for a couple of days, then went out in it and have these issues:

• No cellular data connection
• Speed limit display warning
• GPS showing the car in the wrong location (off by about 1/4 mile)
• iPhone app not showing up to date info (likely because car has no data connection)

I tried restarting the PCM, switching the guest user then back to mine (quickly, I didn’t turn off the car.)

Not sure what to try. I opened a case with PCNA thinking it might be all related to the data connection being lost and something they can do with Verizon on their end. After reading this, I’m guessing I might have to take it to the dealership.

I've had my 4s for 3 week now. I'm getting the "Assistance Systems Error" and "Headlight Control Error" intermittently.

Upon start up I will either:
Have no messages and no messages come on for the entire trip. All assistance features work perfectly for the trip. The car behaves exactly as it should.

Or....about every 4-5 times I start the car...get these messages within a few seconds of starting the car. They will stay on for the entire trip. I lose all the assistance functions for the trip: blind spot, cruise control, traffic sign recognition, lang change assist, warn and brake, auto high beams.

I've done a factory reset but that hasn't solved the problem.

I now cross my fingers each time I start the car to see if these message appear
