Service screen errors

Used LLM to tell me what these are and they told me these could be critical errors. I’m looking to buy this used Tesla and it’s almost too good a price so I’m trying to see if there’s anything glaringly wrong. Does anyone know if these alerts are to be concerned about?

According to a reddit thread posted earlier this year, this was a firmware bug. Try taking it to a service center and asking them to diagnose the code.

Stop using hallucinations generators, or don't poke tools that are deliberately hidden behind a password and a warning stating that they're not customer facing. These diagnostic messages aren't displayed normally for a reason. a034 on EPAS3* is a known software bug and means nothing. You should probably get a pre-purchase inspection anyway, as mechanical things can be way more expensive to fix.

You shouldn’t concern yourself with these errors unless you have a drivability concern or the show up outside service mode. It’s a known bug on HW4 cars after the winter update iirc or at least that’s when I noticed it showing those.
