Three usage questions- brakes and Comfort Control

Hello, I'm new to obd11, and I have three questions that seem a little confusing to me.
See my responses in blue below

I have a 2015 TDI, without electronic parking brake. For wear and noise reasons, I want to replace my rotors and pads, and I can't seem to get the calipers to back off. I don't have the line service options that I see in other OBD computer systems, and I just was hoping to get a step by step on how to get the calipers to release-i don't want to break anything.

Here's a video showing the OBD11 steps for opening the calipers (the video uses now obsolete GUI screens - but the basic process is the same with the current OBD11 software):

Note: although not said in the video - this procedure places a heavy electrical current-drain on the battery. Please be warned that it is NOT good for the battery to fail whilst undertaking the process. So, if there is any doubt about battery health- connect a suitably sized electrical battery charger to the car before commencing.

My second question relates to brake bleeding, I don't have any air in the system, and I'm not replacing anything in the hydraulic system, so I'm wondering if I need to go through the electronic brake bleeding steps, or I can just vacuum bleed the brakes, which is what I would expect.
If you don't have any problems with air in the brake-line, I suggest that you don't tinker !! But yes, just the normal process is what's needed

My final question relates to enabling the key fob window control, from everything that I've read the options should be within the Comfort Control Module, and I cannot seem to get that module to load/connect, it's almost as if the module is not installed in my vehicle?

MQB platform cars (like your Golf mk7) don't have a Comfort Control module. instead, these vehicles hold the "comfort functions" in the Central Electrics Module which lives @ address 09 on the CAN network

Thank you very much for your help!
My pleasure!!
