Thank you for all the inputs, the problem I observe is:
1. The oil reading always displays "Not available" no matter what I do - I tried to check it in the morning on a cold engine as well.
2. It doesn't seem to react to the "press Cruise Cancel two times in 2 seconds".

2. It doesn't seem to react to the "press Cruise Cancel two times in 2 seconds". Either I am doing something incorrectly or something is stuck in the car's "software".

Also, not working start-stop most probably means that I need to replace the main battery anyway.

If the battery current state doesn't affect the oil reading, I see only these remaining options to try:
a) hard reset - I hope it won't have any negative consequences on the car.
b) inspect the oil level sensor for leaks.
c) check oil readings with a diagnostic tool

Questions:

Does anyone know (or have any photos) where the oil level sensor is located? My understanding is that there should be some external cables around the sump which are inspected for oil leaks - are they accessible simply under the car or it requires disassembly?

Anyone knows a good mechanic with the right diagnostic tools not far from Gloucestershire/Bristol area?
