Like others on this thread I have ongoing issues with the MMI in an 2020 A3. The system gets stuck on the initializing screen(s) [initializing across the phone, media and navigation tabs; with a black back-lit MMI screen] maybe once or twice a week. It might be that the MMI goes into a 'deep sleep' and it has problems coming out of that when there is interference from a 5G signal. The only way to get out of this hang is to press and hold the power off button on the volume control disc on the gear stick console for about 20 - 30 seconds.
More frequently, I also get a large parking sensor fault graphic in the cockpit with a beep when I turn the ignition on that goes away after a couple of seconds. I don't know if this is linked to the MMI issue or not. The parking sensor fault appears irrespective of where I park the vehicle
The car has already been back to the dealership for a software update this month but the above issues remain.
Can somebody who's had the software update applied to their A3 do me a favour and post the version information that can be found on the Settings>General>Version screen on the MMI?
I have:
Software version
3620
MMI software version
release-35.12-2126-SNAPSHOT-28.06.2021-13:58:42
Navigation database
V03959808JK_P0421_EU_2020.06
Media driver
CL35_MIB3H_AU_ER_G4x_2102500PROD-1
Gracenote database
Region=EUROPE-Version=7
Hardware
H8Y0035043
Software version
MHI3_ER_AU_P3620
It would be nice to check if these are all correct and current.
The car is booked in for another session at the dealership. This is pain given that these errors are intermittent. I suspect the dealership will just report back 'no fault found' unless they can interrogate any boot logs in the MMI. Do MMI initialization errors get recorded in the OBD2 diagnostics system?
Thanks!
