The Dynamic System Control (DSC) is one of BMW’s ways of keeping drivers safe on the road. It functions as a suspension system control that uses a variety of sensors like the vehicle, engine, and steering angle sensor to gather information about driving patterns.

The DSC helps to adjust internal operations in your BMW to increase performance and efficiency. It is also responsible for maintaining traction on the road and aids the stopping mechanism in your car’s wheels during an emergency. However, like many other systems and car components, the DSC is susceptible to failure. If you own a BMW, it is important to understand the common causes of failures so you can take better care of your car.

6 Common Causes of DSC Failure in a BMW

Because the BMW DSC relies solely on information from the sensors to determine the car’s functions, its failure is mostly attributed to sensor issues. Hence, here are some common reasons for DSC failures.

1. Defective Steering Angle Sensors: The steering angle sensor is responsible for detecting the direction of the BMW steering wheel to tell the direction the driver is going. Due to poor alignment, electrical problems, and wear, the steering angle can fail. When it fails, the DSC loses its ability to direct the steering inputs of the driver, thus resulting in bad driving performance.
2. Electrical Problems: Since the DSC is an electrical component, problems like faulty wire connections, blown fuses, and relays will affect its efficiency. Also, the DSC requires a fair amount of power from the battery to function. Hence, when there is a problem with the battery connection, the DSC can fail.
3. Wheel Speed Sensor Problems: Contamination of the wheel speed sensors by dirt, debris, and other contaminants can cause inaccurate speed measurements in the DSC. Physical damage could also be a factor and when this happens, the DSC cannot tell when the car wheels are within normal functions or not.
4. Anti-lock Braking System (ABS) Module Failure: The DSC works hand-in-hand with the ABS. So, a failure in the ABS can also be a reason for a failure in the DSC. ABS failure can be caused by a variety of factors ranging from faulty pumps to electrical problems.
5. Low Brake Fluid: The DSC needs an adequate amount of fluid (brake fluid) to function effectively. Brake fluid is essential in the hydraulic function of the DSC as it creates the hydraulic pressure required to trigger the activation of brakes when the car slips. However, when the brake fluid is below optimum, the DSC could fail to perform.
6. Faulty Tires: The tires play a significant role in maintaining stability on the road. When your car’s tires are worn out, extra pressure is put on the DSC system to find balance, if this happens often, the DSC could eventually wear out and fail.

How to Tell if Your BMW’s DSC is Failing

Before the DSC eventually breaks down, it gives certain signs to tell the driver it is failing, some of these signs are;

• Dashboard Warning Light: Upon detection of an error in the DSC system, the DSC, ABS, or Traction control warning lights are illuminated. If these lights blink intermittently or remain lit for a very long time, you should look into the DSC.
• Reduced Traction Control: Another sign of DSC failures in most cars is a loss of traction. If you notice that your car has less traction even when driving under normal conditions, the DSC should be checked for faults.
• Strange Noises: Failed DSC causes ABS to malfunction and in turn, produce a buzzing or clicking sound, especially when braking or accelerating.
