Plugged in my new scan tool today for the first time and I have a few faults showing but no dash warning lights. Any idea of the problem and should I clear them?

Usual routine is to clear them all, then rescan after a few days to see if they return, could be historic.

If they repeat, you need to investigate further.

 “If it ain’t broke, don’t fix it” -where’s the fun in that?

If there's something you need to know about, you'll get a dash message and / or warning light. for everything else - ignore unless you have an issue.
