Car issues - help kindly requested :) ABS - Auto HVAC - Central electrical system - Wipers - Canbus - Door electrical system - Steering assist

Hi, I ran a vcds and got up a few issues. I have searched the internet and tried a lot of diagnostics but probably overlooked some, or done them wrong. So I am asking here directly, if there are already good topics on them please link to them  
I am a newbie and hope you understand the fault codes better than me, also tried to look them up on ross tech, but can't quite manage to wrap my head around what some of them mean. I have checked the fuses like a thousand times, both under the hood and the one in the car. Searched milennias for relay diagrams, but no luck. Sent a mail to skoda asking for one, will see where that goes. This is a car I will recycle or sell as parts when i am done with it, fixing it is a hobby  

Skoda octavia 2005 mk2 combi 1.9 tdi. 

- Battery changed this spring (2021). 
- Bought new horn.
- bought new ABS sensor, ring too if necessary.
- Swapped the engine summer 2020 (blown head gasket). (old one: 308 000 km, new one: 133 000 km, car now: 319 000km)

All help is appreciated

 Abs sensor
- I have already bought a new sensor, just haven't replaced it yet. Most likely that will fix it, no?

- Should I put in a new ring aswell, or is it more work for no necessary reason?

Auto HVAC
- there is no AC refrigerant in the system. Expensive to fill up, is it possible to do it yourself?
- is that what is causing both issues?

central electrical system
- Is terminal 30 what goes directly to the battery?
- What relay goes to the horn? there is no clicking sound when i press the horn with ignition on :(
- I have connected reverse camera to reverse lights. New joying radio connected to lights as well as an amplifier. (so it turns on with the car) better suggestions?
- Fuse for interior light is good, and they work, so don't know why it's complaining?

steering wheel - wiper switch

- I think this one is the interval switch on top of the stick. don't notice any problems.
   - Any point in fixing?
- My back wiper doesn't work, i think the motor needs to be replaced. Any suggestions as to how to shock it to see if it starts spinning?
    - Functions sometimes, very rare.
    - No sounds, when turning the back wiper on. clicking sound behind wheel tho. 
    - 4 pins so not sure how to shock it, suggestions?

CAN gateway
- Not sure what this means. Radio is swapped so makes sense that it can't find it.
    - Is that a problem?
- What does the first fault mean?

Door electrical system - driver side

- Swapped the old broken driver side side view mirror, maybe a different bulb code messing up?
- Couldn't see any obvious breaks behind the door cover.

- Suggestions?

The entire scan is added as an attachment in case you want to take a look. the only fault I didn't add was the auxiliary heater where the heater element is defective. took the cable off when i swapped the engine 'cause I don't need it, so don't plan on replacing it, unless you guys want me to ofc!
