- Check Tire Pressure:
- Start by using a tire pressure gauge to check each tire and ensure it matches the manufacturer’s recommended levels (usually found on a sticker inside the driver’s door or in the owner’s manual).
- Inflate or adjust the tire pressure as needed.
- Reset the TPMS System:
- Turn the ignition on without starting the engine.
- Using the steering wheel buttons, access the “Service” menu on the digital dashboard.
- Select “Tire Pressure”, then choose “Restart”.
- Confirm the reset and drive for a short while to let the system recalibrate.
- Inspect TPMS Sensors:
- If the error persists, one or more TPMS sensors might be damaged, or their batteries may be depleted.
- Visit a Mercedes-Benz service center to test and replace the faulty sensors.
- Perform a Software Update:
- If the sensors are functioning correctly, the problem might be software-related. Check with your dealership to see if there are any updates available for the TPMS system.
- Seek Professional Assistance:
- If resetting and updating the system doesn’t fix the issue, consult a Mercedes-Benz service center for a full diagnostic test.
Preventing Future Tire Pressure Sensor Faults in EQA
- Regularly check your tire pressure, especially during temperature changes or before long trips.
- Replace TPMS sensors every 5-7 years or when changing tires to prevent battery depletion.
- Always reset the TPMS system after tire rotations or replacements.
