What's the BMW X3 55c4 fault code?

The BMW X3 55c4 fault code is when there is a problem with the DSC control or unit of the steering angle sensor. If the steering angle sensor on the vehicle is bad then there are going to be a couple of complications. The first is that the wheel is going to feel loose and wobbly when You are driving. This is because the sensor is in charge of knowing how the tires are aligned. If it can't do that then the wheel will not have the proper pressure applied to it. This in turn will make it so Your car is slow to react to turns, and is not a safe way to drive. Secondly, the tires and alignment will begin to degrade if You drive this way, which will lead to other problems. If the sensor is failing You need to have it fixed right away.
