It might be trial and error.
There should be a bulb/lamp option for you to change.
On the Skoda Octavia 2017 you can find the option
Controller 09 - Central Electronics
10 - Adaptations
Find the coding for the lamp you are looking to change
The below are the rear fog lights on the Octavia, left and right, so you need to identify the lamp you need to change
Leuchte26NSL LA72
Leuchte27NSL RC6
Select the lamp you want and it should give you an option to select the lamp type.
The top value value for mine was LASTTYP which relates to the bulb/lamp type.
Once you select LASTTYP you will see a long list of different lamp types.
This may be the solution?
Hope this helps
