Why is my mercedes Sprinter cruise control not working?

The Mercedes Sprinter cruise control not working can be caused by many different reasons such as a faulty brake pedal switch, a blown fuse, or a defective speed sensor. The cruise control is a convenient feature but if it does not work You can still drive the vehicle with no issues. The best thing You can do is use an OBD scanner to check to see what error codes are pulled from the ECU. If the brake pedal switch is bad You will know because the cruise control will engage and it will automatically turn off. If it's a blown fuse You can simply find the fuse panel and check to see if it's bad or blown. The speed sensor is essential for the cruise control to work and You may notice this as a problem if Your car's speedometer is off or having intermittent problems.
