Controller and Bluetooth Coding

Hello,

My 2010 Octavia was submerged in water due to torrential rain and so after restoring it at a shop both the controller and bluetooth box were unrepairable. I managed to buy the same part numbers (below) over ebay but it turned out that they are not a simple plug and play and still have some glitches even after trying to play with the coding. Side mirrors move in opposite directions; down instead of up and right instead of left and so on. An external chip was added to the bluetooth box which I didn't have/need before but still I can't get it to work seamlessly on all phones. Is there anyway I can get the original coding for both boxes to compare it to what's on the current boxes and change it to what it should be?

Let me know what info is needed and I'll do my best to provide it. Below is for reference:

Car chassis number: TMBBA21Z5A2006364

Controller part number: 5K0 959 793 A KLO

Bluetooth box: 1Z0035729D

Thanks in advance.
