My 2012 VW Golf wouldn't start at all tonight. The engine won't even turn over, and I get a bunch of error messages when I turn the key halfway. These messages say check airbag, check right turn signal, check brake lights, etc, but I just got the car checked out by my mechanic last month and nothing was wrong so I'm guessing the error messages are glitching. It dropped about 20 degrees overnight and snowed several inches, but I live in the Midwest where even blizzards haven't taken my car out of commission. In fact, I've driven this car for five years and never seen my car do this. I honestly don't know anything about cars, so I'd really appreciate some help with this one. I've attached a video with what I see when I try to start the car.
