Had a similar experience with our S5 only today.
Returned to the car after about a 15 minute stop to pick up some items.
Booted up the car and went to move away.
The car gave out numerous bongs and warning lights on the dash.
Very similar list to yours.
It allowed me to drive home, but I noticed that there was absolutely NO Regen at all when reducing speed.
If I increased the Regen strength manually, although it changed the level on the drivers display, it made zero difference!.
The car had NO Regen at all and the fault codes stayed displayed all the way home.
When I reached home, I powered down the car and locked it.
I returned back to the car about 30 minutes later, because I needed to unexpectedly go out again.
Car booted up just fine and no return of the warning messages and the Regen had been resorted !.
I think, what may have caused this problem was when I booted up the car the first time.
The car was facing directly into very strong sun light.
This sudden influx of light, directly into the camera, is not liked by the car, in its normal boot up process.
The ZS EV did suffer from a very similar situation, when strong light hitting the camera suddenly, the car would react by throwing up numerous error on the dash panel.
After I returned home, I had to go back out again about one hour later.
All errors had reset and the Regen returned back to normal.
I tend to think, that when a false trigger happens, it set off a train reaction of errors that the car has difficulty dealing with and the error just multiply.
