Hi, I had similar problems with my Skoda Octavia Est 2.0 TDITDI 150 SEL DSG 1st Edition, within a week of getting it, in March 2020.
I tried to replicate the error (having dealt with other car dealers) and finally found out that it had to do with the car key not being in close enough proximity (enough for normally functioning cars, but not mine) to the ignition (push start). As long as I kept my key touching the 'push start' when I started the car, I would not get the error. Also, the key had to be close to the start button (on the seat/dash) just in case the 'start/stop' switched the car off; if it was not close enough when that happened, the errors mentioned above would recur!
I mentioned this to the car dealer I got it from, who is not located close to where I live, and he casually asked me take it to the local Skoda dealer and said that he had not idea about problems such as this, till now.
Later on I started having problems with my 'SOS' system activating for no reason, after a feedback like noise (like when a mic is taken out or plugged into a speaker's socket).
This is when I took it into my local dealer's. They kept it in for 3 days and they did "software updates". While I was there , I heard them talk about random cars with "recalls" and if a specific car was a car with "all those recalls" when asked for updates.
Finally, when I got my car back and on the very same day, while I was setting up 'mySkoda' and 'user' on my car, the rear traffic alert, parking sensor and emergency brake errors popped up once, but did not stay active (unlike how it would before the updates). Also, now I do not need to keep the key close to the push start to prevent these errors from happening. One person who was working on my car acknowledged that they knew of this error and that during an "update for a car" they had to stick the key to the ignition, or the update would not take!
The SOS error seems to be slightly worse than earlier (but I only noticed these after a week or more of driving around) and I think, possibly, this seems to happen in specific areas that I drive in (though that observation is based on one specific area close to my work). As I do not drive regularly, I am not sure if the errors are being noticed more, as I am driving more than usual, at the moment.
I hope that all makes sense and is helpful in some way.
