Tire Pressure Sensor Fault in Mercedes-Benz EQC

October 22, 2024 TirePressureFault Mercedes-Benz 0

The TPMS (Tire Pressure Monitoring System) in the EQC monitors tire pressure to ensure optimal performance and safety. However, a tire pressure sensor fault may arise for several reasons:

  • Low Tire Pressure: A small drop in pressure, often caused by temperature changes or slow leaks, can trigger the TPMS warning.
  • Faulty or Damaged Sensors: Over time, TPMS sensors may degrade or become damaged, particularly after tire changes or exposure to rough conditions.
  • Battery Depletion in Sensors: The TPMS sensors have small batteries that typically last around 5-7 years. Once the battery runs low, the sensor may fail to function properly.
  • Improper System Reset: After tire rotations or replacements, the system might not recalibrate automatically, requiring a manual reset.
  • Software Glitches: Occasionally, software bugs may trigger false warnings, necessitating a reset or software update.

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

  1. Check Tire Pressure:
    • Use a tire pressure gauge to ensure each tire is inflated to the recommended pressure levels (you can find this information on a sticker inside the driver’s door or in the owner’s manual).
    • Inflate or adjust the tire pressure as necessary.
  2. Reset the TPMS:
    • Turn the ignition on without starting the engine.
    • Use the steering wheel buttons to navigate the “Service” menu on the dashboard.
    • Select “Tire Pressure”, then choose “Restart”.
    • Confirm the reset and drive for a few minutes to allow the system to recalibrate.
  3. Inspect TPMS Sensors:
    • If the warning persists, one or more of the sensors may be damaged, or the sensor batteries may be depleted.
    • Visit a Mercedes-Benz service center to test the sensors and replace them if necessary.
  4. Software Update:
    • If the sensors are in good condition, the issue might be software-related. Check with your dealer for available software updates.
  5. Seek Professional Assistance:
    • If resetting and updating the system doesn’t resolve the issue, consult a Mercedes-Benz service center for a full diagnostic test.

Preventing Future Tire Pressure Sensor Faults in EQC

  • Regularly check your tire pressure, especially before long trips or during seasonal temperature changes.
  • Replace TPMS sensors every 5-7 years or when changing tires to avoid battery-related issues.
  • Always reset the system after tire rotations or replacements.
