Errors after diagnostics

Hello friends, today I did diagnostics on my A4 B9 3.0tdi and the errors from the attached photos came out. I can't find anything specific about them on the internet, and I'm hoping someone here can help me figure out what these errors are, where to look for the problem, and how to fix it..I also want to ask what does this mean from the last picture and is it related to the headlights, it won't let me enter the modules as well as the 46 module, it says no communication with the module, what could be stopped.
Thanks in advance friends
