Fault codes HELP !!!

[RedStallionA3]

I am getting new fault codes coming up and I'm pretty sure shouldn't drive my car until codes are cleared and problems fixed I think, here are the codes I'm getting

P2681 - SAE Engine coolant bypass valve control circuit/open

P2181 - performance malfunction in cooling system

P00B7 - engine coolant flow, Low/performance

P056200 - system voltage low voltage

P173400 - starter release from the selector lever sensor system

Those are secondary diagnostic trouble codes and also those codes are coming up twice for some reason. I will take a picture of what autozone printed out when they did a engine scan. Picture will be attached. Are these things I can do myself I'm wondering ? It seems like sensors but hopefully you guys can help me out answering these questions thank u so much everyone.

Do you have access to a VAG scanner? If not see if you can get your hands on one. Ideally if you could get access to Ross-Tech that would be even better.
