I have a Octavia 2011mod. The problems started With the rear left door electrics not working. The next Day the rear right door got the same problem. When Reading codes with odb11 i get the codes shown in the pictures. Anyone got a clue about this? This is beyond my knowledge...

From what I read on the pictures is that both control modules in the rear doors are not functioning. 
 

I would start with a fuse.

Then onto whether it’s receiving power. 
 

If the module receives power, module may have gone faulty

If the module isn’t receiving power, I’d look to the door wiring.

The wiring between door and chassis can become frail and they do break from time to time and this can solve all of the electrical issues in one fix. 
 

for them both to have gone like this in a short period of time, is a little unusual though. 
 

good luck with it
