Red & Yellow Park Brake Light Stays On Mercedes-Benz
The red and yellow parking brake may come on and stay on even when you release the parking brake. This problem may affect Mercedes-Benz S-Class W221 and CL-Class.
If the PARK brake stays on all the time, even if you try to release it by pulling on the switch on the side of the dashboard, the vehicle may have a failed parking brake component. The parking brake cable may have broken, or the module may be defective.
On the Mercedes-Benz S-Class W221, the problem will most likely be a failed parking brake module (EPB) with part number A2214302949. This is a common problem in the Mercedes Benz S class, chassis W221, and models such as S320, S350, S400, and S550. This problem also affects Mercedes Benz CL-class chassis W216/C216.
