I ran a complete scan of my A6 and I found the below 2 errors. I've tried looking online but didn't understand them completely. Did anyone get these errors or know what is the fix for this?
I don't have an Check Engine light but when I read online, it said the below might cause Check Engine if not worked on.

One may have caused the other.
Have you had this TSB done?

"Intake air temperature is usually above 140°F (60°C) in the freeze frame data of the diagnostic log"
Yours is 87ºC so you are a candidate if you haven't already had it done.

I don't think this is done my vehicle yet. I'll call the Audi dealer to know more about this...
Since this is a TSB, they may not do it for free, which I have to check. Thank you for pointing
