I have a 2011 TDI. Today I pulled up into a parking spot. I changed my mind and reversed to go go to a different spot. As I reversed, the wheels locked, I heard a creak and couldn’t move. I put it into drive and I could move. This is the first time it ever happened. What the hell was that? That was scary. I’ve never had this happen on any vehicle. Was it a parking break issue? ABS?
