I'm not sure it's just a simple microswitch issue.
When I had the second lever replaced the Skoda tech mention there's a mixture of switches, hall effect sensors and small solenoids and some functions are canbus with the gearbox. He thought the fault was a canbus comms issue.
If that's true, its a much more complex issue

The failure is due to what VW call silicate build up in the micro-switch for the park position. So basically corrosion, that causes a resistance that confuses the mechatronics unit and or ECU.
The ECU will be expecting either a fully open or dead short from the switch depending on the gear selector position. i'm not sure if the switch signal path goes through the can-bus, but in any case, any deviation from the expected voltage (switch position dependant)
will confuse the control modules, thus causing the error.
I used to see this kind of fault when I serviced video recorders, that used a mode select switch to determine the position of the mechanical parts (play, stop, record, fast forward etc.)
Of course the switch could be got at and replaced, unlike all this modular nonsense crammed into cars these days.
If this indeed the failure mode its common with microswitches. I'm an engineer who works with sensors that use microswitches. One fix that will stop the problem for a while is to put a much higher voltage through and operate the switch. This burns the contaminated off the contacts. It is sometimes permanent but normally returns. If you can get the switch off it can be replaced or you can put it in an ultrasonic bath with IP Alcohol.

Does anybody have a reference to the official Skoda service notification about this issue? Had another occurrence this morning and I want to go in to the dealer with information.

Thank you very much!

It's a 6.5 inch screen. What is FL, PFL?
Device part number is 5Q0035874B

If you want to know the part number, it’s in the settings under system information. If you want to know the name of the system, if it doesn’t have sat nav, it’s a Bolero, if it does have sat nav and it has a smaller screen (5.8 or 6.5 inches on the PFL) it’s an Amundsen. If it has nav and a larger screen (8 inches on the PFL) it’s a Columbus. On the FL, the Amundsen has an 8 inch screen with swivel wheels on it, the Columbus has a 9.2 inch screen with no swivel wheels, just some touch buttons on the left.
Thanks for the quick response! I'm going to go and try and work it out. It's got Sat nav but not sure what size screen.

Is there an easy way to do this? It not obvious to me.

Hello, just bought a used skoda octavia 1.4 estate. Still in warranty until December. This message flashed up today for about 1/2 a second.
What should I do. Can I take my car to any dealer for this to be checked. Nearest dealers are Reading, Newbury, Winchester

Some of you points are correct, some maybe correct and some irrelevant.
Regarding the last point on functional safety, I don't give a monkeys. If I repair it and put it back in and it works, who cares?
