The loss of comms codes can be just an electrical glitch. The knock sensor may be more worrying though.
As I understand it the knock sensor alerts the ignition system if the gas is low octane and retards the ignition. If its not working and you have pre-ignition the electronics would not be compensating. Best use decent gas in the meantime. Guys smarter than me may add more to that.
I'd clear them down and check back in a few days to see if they reappear. I'd lay bets that the loss of comms codes dont come back but it may be worth watching the other one and then reposting.
