Why does the dynamic stability control and yellow brake warning lights stay on continuously a 2002 BMW Z3 Roadster?

1. Low brake fluid: If your cars brake fluid level is low, it can trigger the dynamic stability control and yellow brake warning lights. Check the brake fluid reservoir and top it up if necessary.

2. Faulty brake fluid sensor: A faulty brake fluid sensor can also cause these warning lights to come on even when the brake fluid level is full. Check the brake fluid sensor and replace it if necessary.

3. Wheel speed sensor issue: If one of the wheel speed sensors is malfunctioning or has a bad connection, it may cause these lights to illuminate.

4. Faulty ABS module: The ABS module is responsible for controlling the anti-lock braking system, which works in conjunction with the DSC. If the ABS module is faulty, it can cause the DSC light to come on.

5. Electrical issue: An electrical issue, such as a short circuit or a loose connection, can also cause these warning lights to come on. Have your car inspected by a qualified mechanic to diagnose and fix the electrical problem.
