That is not a scan with VCDS.
Do you know that you can buy a VAG 409.1 cable from Ebay or Amazon for about $15, and download the FREE VCDS-Lite from Ross Tech.
This will read all codes from all modules. Acquiring a VCDS scanner would be the best thing you could do.

The ECU (which is the Engine Control Module) is not related to door problems or any of the comfort control systems.

You actually have several faults, I again suggest you start by installing the original ECU (ECM) back in the car.
I strongly recommend that you don't do anything with the engine bay wiring, without a specific fault being diagnosed.

You have a number of faults that I could help you with, but you need to fix the obvious first, and get the engine running.
