Anyone else discover that you can get a false oil level reading with the electronic oil gauge?

Anyone else having a false oil level reading on their 2015.5 S60? I let it set overnight reads between low and full, drive it in the morning, park it for a few hours , recheck reads full. I have found that if it is between full and low it might need about 4 ounces to top it up, seems a little weird.

I own two of them and have had no issues. Just watch the side mirrors as they do have a tendency for the glass to fall off.
