Audi A8 D2 with various problems ..

Moin forum dwellers !
I'm new here, and I'm about to have something that I'm gonna have to bother you with.
3 days ago I bought my first European car ..
Until then I have only driven Americans and will continue to do so, but I got an A8 in between .. after the few days and a few minor repairs, I have already gained the device quite fond ..
I think I'll keep the "little" too and he gets his "gnade bread" with me.. I think he's worthy of maintenance.
And here we are on the subject:
Mine has from factory probably a auxiliary heating .. Display works, and according to that the heating also runs ..
But I'm convinced she won't start..
The guide gives little information that makes the function check .. My diagnostic device (SUN Modis International) does not want to give any information about the SH ...
I would have liked to have activated this ..
Another tip can give me why my glove compartment has conspired against me ..
Things only open their mouths if it wants to.. but it can not be lured by the pressure on the button .. this is annoying ..
The built-in phone in the center console is moussetot ... which is not bad .. but I would like to have an info on how to use it ... Unfortunately, the buttons are all white, i.e. scraped off .. is the middle arm replacement ...

There would be 2-3 small things, but I want not only to fraen but also to make myself ..
As discussed here in the forum, there seems to be no "free-accessible" technical information about the car ..
I'd like to check the electrics.. without plans but it is hard fuzzy ..

So... now you have something and I hope I can dust some info's ..
Thank you very much in advance

If I can help : just call ! :-)
