5E24

What Code 5E24 Means

Code 5E24 belongs to the Dynamic Stability Control (DSC) system and points to a fault in the wheel speed sensor circuit. In this case the car is a 2004 BMW E46 Touring with a DSC MK60 module. The owner replaced sensor 1 and cleared the codes, but 5E20 (the same type of fault) came back immediately. Swapping the connectors for sensors 1 and 2 didn't change the error, and the wiring to the control module was checked and found good.

DSC uses wheel speed sensor signals to manage wheel slip, directional stability, and the anti-lock braking system (ABS). The DSC MK60 module reads those signals and sets the corresponding fault code when it sees implausible data or an open circuit. Code 5E24 can point to a problem with a specific sensor or its electrical circuit, but in this case replacing the sensor and checking the wiring didn't clear the fault, so it needs deeper diagnosis.

Symptoms

• Warning lights on the instrument cluster for codes 5E20 or 5E24.
• Brake booster failure (per the owner's report).
• The code comes right back after clearing — something is keeping it alive.

Diagnosis and Repair

For accurate diagnosis, scan the car with BMW diagnostic equipment: ISTA/D or INPA. These systems read current codes, show live sensor parameters, and run component tests.

Check the following:

• Condition of the wheel speed sensor connectors (plug) and contacts.
• Continuity of the wiring from the sensors to the DSC control module.
• Correct sensor installation (air gap, mounting).
• Possible faults inside the DSC MK60 module itself.

If the wiring and sensors show no obvious defects, consider an internal fault in the DSC control module.

Secondary Problems

Ignoring code 5E24 and the brake booster failure can reduce braking effectiveness and compromise directional stability, especially in critical situations. DSC may be disabled, which raises the risk of an accident. Don't put off diagnosis and repair.
