2019 SE two days old - question on noise when opening driver's door

So glad to have found this group! As the header says, I bought my 2019 SE Tiguan on Monday. One thing we noticed is when I open the driver's door, there is a motorized sound for about 5 seconds that seems to be coming from the rear of the vehicle as though something is adjusting. Anyone have this or know what it is? It happens when the key isn't nearby too.

Thank you!

UPDATE: VW service said it was the fuel pump priming for a fast start.
