A3 2012 black edition electric fault

Hi,
I have a 2012 audi a3 black edition and ive started coming across a few issues which originally i thought i needed a new wing mirror indicator on the drivers side as it stopped working. Then the drivers door wouldnt lock, wing mirror wouldnt move when using the rotator inside the door and the window wouldn’t go up automatically with 1 click on the button id have to hold it down.
if anyone has any advice that would be great thanks.

Thanks for that, found a few wires which were broken. I found online a cable repair set which comes already assembled with the plug. Do you know if these are already connected up in the correct colour code or would i need to change it? Thanks
