The TPMS system in the E Series works similarly to other Mercedes models but might encounter specific issues depending on vehicle age and usage. Common causes include:
- Low Tire Pressure: Even a small drop in pressure can trigger the system.
- Sensor Battery Depletion: TPMS sensors use a small battery that can run out after 5-7 years.
- Damaged TPMS Sensors: The sensors can get damaged from rough terrain or during tire replacements.
- Improper Reset After Tire Change: When tires are changed or rotated, the TPMS needs to be reset manually.
- Software Malfunctions: Occasionally, the system might need a software update or reset.
How to Fix Tire Pressure Sensor Fault in Mercedes-Benz E Series
- Check Tire Pressure:
- Make sure all tires, including the spare if applicable, are inflated to the proper levels as indicated in the vehicle manual or on the door panel sticker.
- Inflate any underinflated tires to the correct pressure.
- Reset the TPMS System:
- Turn the ignition to the ON position (don’t start the car).
- Use the steering wheel buttons to navigate the dashboard menu.
- Select the “Service” menu, then find “Tire Pressure”.
- Choose “Restart” and confirm the reset. Afterward, drive for a few minutes to allow the system to recalibrate.
- Check and Replace TPMS Sensors:
- If resetting doesn’t fix the issue, you may have a faulty TPMS sensor or dead sensor batteries.
- A Mercedes-Benz service center can test the sensors and replace any defective ones.
- Look for Software Updates:
- Sometimes, the fault is due to outdated software. A quick visit to the dealership might resolve the issue with a system update.
- Seek Professional Help:
- If you’ve tried all the above and still see the error, consult a professional who can diagnose the TPMS system.
Preventing Future Tire Pressure Sensor Issues in E Series
