@Mmmm1987: Hmm........ intriguing problems - do you have access to a diagnostic device (like VCDS, or OBDeleven)? If so, a scan would be very, very useful!!
Apropose of your concern regarding incorrect door modules, I invite that you consider the following 2 x fundamental points:
- ALL MQB platform vehicles have a graphic on the housings of their door modules that indicate their designed positions on the car.
- The other important "variable" about door modules is what side of the vehicle the steering wheel is installed because this determines what dataset is used in the module's firmware.
Even if the modules are installed on the correct car-side, using RH-drive door modules on LH-drive cars does cause problems with UP/DOWN/LEFT/RIGHT mirror switch adjustments. From your description, I don't think this is your problem - but it's something to bear in mind.
Here's a picture showing the nomenclature that VAG uses on their door modules (and my comments):The module shown is for the passenger side - notice that the left-side square is colored white for our RH-drive cars (see RL -second set of boxes which I've enclosed by the yellow highlights on my picture). Incidentally, I suspect the boxes marked ??? are used for what VAG call "special vehicles" - I wasn't sure of this when I made the picture.
Of course the equivalent driver side module will have the opposite (right-side) box colored white on our cars (i.e. on the RL boxes)
So - if you have the inclination, I suggest that you actually eyeball how the boxes are colored on the door modules on your car to confirm the correct modules are fitted.
In my experience, it's highly unlikely that the wrong modules are fitted - but yours is a most peculiar problem IMO. If you haven't had the car from new - maybe the original owner made some "innovative" fitments?

Please don't PM to ask questions about coding, or vehicle repairs. The better place to deal with these matters is on-line, in the forum proper. That way you get the benefit of the expertise of the wider forum! Thank you.
