Tire Pressure Sensor Fault in Mercedes-Benz EQB

October 22, 2024 TirePressureFault Mercedes-Benz 0

The TPMS (Tire Pressure Monitoring System) in the EQB monitors your tire pressure for safety and performance. Here are some common reasons why a tire pressure sensor fault might occur:

  • Low Tire Pressure: A minor drop in pressure, often due to temperature changes, can trigger the system to issue a warning.
  • Faulty or Damaged Sensors: TPMS sensors can fail due to wear and tear or damage during tire changes or rough driving conditions.
  • Sensor Battery Life: The TPMS sensors have small batteries that last about 5-7 years. If the battery is low or depleted, the sensor won’t work correctly.
  • Improper Reset After Tire Changes: If you’ve rotated or replaced your tires, the TPMS may not recalibrate automatically, requiring a manual reset.
  • Software Glitches: Occasionally, software issues may cause a false sensor fault, requiring a system reset or software update.

Steps to Fix the Tire Pressure Sensor Fault in Mercedes-Benz EQB

  1. Check Tire Pressure:
    • Use a tire pressure gauge to check the pressure in all four tires and ensure it matches the recommended levels (found on the sticker inside the driver’s door or in the manual).
    • Inflate or adjust the tires to the proper pressure as needed.
  2. Reset the TPMS:
    • Turn the ignition to the ON position without starting the car.
    • Use the steering wheel buttons to access the “Service” menu on the digital dashboard.
    • Scroll to “Tire Pressure” and select “Restart”.
    • Confirm the reset, and drive for a few minutes to allow the system to recalibrate.
  3. Inspect the TPMS Sensors:
    • If the fault persists, the sensor might be damaged or the battery depleted. A Mercedes-Benz service center can test the sensors and replace them if needed.
  4. Perform a Software Update:
    • If sensor issues are ruled out, the problem may be software-related. Check with your dealer for any available software updates for the TPMS system.
  5. Seek Professional Assistance:
    • If resetting and updating the system doesn’t fix the issue, a professional diagnostic at a Mercedes-Benz service center will help identify the cause.

Preventing Future Tire Pressure Sensor Faults in EQB

  • Regularly check tire pressure, especially before long trips or during seasonal temperature changes.
  • Replace the TPMS sensors every 5-7 years or when replacing tires to avoid sensor battery failure.
  • Always reset the system after tire rotations, changes, or other tire maintenance.
