Battery voltage mystery

Today I decided to check my battery voltage (or alternator voltage) with engine running.
I have a new multi-meter which I assume is accurate. It agrees with my old cheaper Maplins multi-meter.
According to the new multi-meter my battery voltage at terminals is a healthy 14.1V

But checking via VCDS shows battery voltage to be 13.86V a bit low.

Which voltage should I trust? What is VCDS actually measuring, voltage at battery terminals or at some other location?
