Golf/GTI VI :: Getting Stuck Especially When Parking Alongside The Street In Snowy Winter

This is the first snowy winter that my car is going through. Often times, especially when parking alongside the street, my car gets stuck. So I usually try the reverse and forward motions couple times and most of the times I'm able to get out of the snow. But while doing so, sometimes the engine reaches high rpm because of no traction. And when i get stuck a lot i usually have to do this a few times to get unstuck.

Today for the first time, after a terrible 20 minutes of trying to leave my works parking lot, some errors came up on the screen for just a bit. The brake error system, airbag system, tire sensor flashing, steering wheel symbol, and i think one other error but just do not remember which. About a min or 2 after that i got out of the parking lot on a regular road with less snow and while parked at the light all the error symbols went away besides the airbag one, which eventually went out when i got home.

What might have caused it or if its a serious issue or not. And also, is getting the engine to high rpms when trying to get unstuck in snow piles bad or does it eventually mess it up? Just getting tired of this snow.
