Have you tried clearing the faults? Are they historic perhaps? If they come back then you have issues but think I would try clearing them first.

If you didn’t have VCDS you wouldn’t even know these “faults” exist. Does the car drive well? Does everything work as it should?
I haven’t checked my car for codes for months, as long as it drives fine I’m ok with that. You’re nervous as you think you might be buying a “ lemon” but none of those codes seem major but I get it.
Did you get any form of warranty with the car?

The start buttons have been known to get dirtied up and need cleaning or replacing. There are threads on here how to do that but I think you’re worrying over nothing but that’s just my opinion, it’s your money you’ve spent and your decision what to do.
