2004BMW545i

About 80% of the time when I put my key in and turn it, the steering wheel will move into position and vibrate like crazy when doing it. When it first starting doing it, I thought it had something to do with the engine vibration, but after a while, I would just turn the key enough to turn on the accessories and when the steering wheel moves down into position, it still did it.

Does anyone know how I can fix this?
