The TPMS in the GLE Series is designed to ensure that your tires are at optimal pressure, but occasionally, a tire pressure sensor fault may occur due to the following reasons:
- Low Tire Pressure: Even minor drops in tire pressure, often due to temperature changes or leaks, can trigger the alert.
- Faulty or Worn Sensors: TPMS sensors can fail over time, especially after tire replacements or exposure to rough conditions.
- Battery Depletion: The TPMS sensors are powered by small batteries that typically last 5-7 years. Once the battery dies, the sensor stops working.
- Improper Reset: After tire rotations or replacements, the TPMS might not automatically reset and requires a manual calibration.
- Software Glitches: Software issues can sometimes cause a false tire pressure sensor warning, requiring a reset or system update.
Steps to Fix the Tire Pressure Sensor Fault in Mercedes-Benz GLE
- Check Tire Pressure:
- Use a tire pressure gauge to ensure all tires are inflated to the manufacturer’s recommended levels, which can be found inside the driver’s door or in the vehicle’s manual.
- Adjust the tire pressure as needed.
- Reset the TPMS System:
- Turn the ignition to the ON position without starting the engine.
- Use the steering wheel buttons to access the “Service” menu on the dashboard display.
- Navigate to “Tire Pressure” and select “Restart”.
- Confirm the reset and drive for a few minutes to allow the system to recalibrate.
- Inspect TPMS Sensors:
- If the fault persists, a sensor may be faulty, or the battery might need replacing.
- Visit a Mercedes-Benz service center to have the sensors tested and replaced if necessary.
- Perform a Software Update:
- If the sensors are working correctly, the issue might be software-related. Check with your dealership to see if a software update is available.
- Seek Professional Help:
- If the problem persists after resetting the system, a diagnostic test at a Mercedes-Benz service center can identify the root cause.
Preventing Future Tire Pressure Sensor Faults in GLE Series
- Regularly check tire pressure, especially during temperature changes or before long trips.
- Replace TPMS sensors every 5-7 years, or when changing tires, to avoid battery depletion.
- Always reset the system after tire maintenance or rotations.
