All About Mercedes-Benz TPMS Sensors

One such groundbreaking development is the Mercedes-Benz Tire Pressure Monitoring System (TPMS) sensor—a revolutionary technology that has enhanced tire safety. Let’s understand the working components and benefits of Mercedes-Benz TPMS and how to reset its light.

In the ever-evolving world of automotive engineering, the pursuit of safety and innovation reigns supreme. The automotive industry, driven by a commitment to excellence, continually pushes the boundaries to provide drivers with unparalleled comfort, performance, and security. 

Working Of A Mercedes-Benz TPMS

The Benz TPMS sensor alerts the driver when the tire pressure is low. Regardless of the type of tires in your vehicle, a TPMS can help enhance fuel efficiency and tire life. Here’s how a Mercedes-Benz TPMS sensor works using the following components


Each tire is equipped with a small sensor mounted on the inside of the wheel rim. These sensors continuously measure the tire pressure and transmit the data wirelessly to the central control unit.

Central Control Unit

This unit receives the data from the sensors and processes it to determine the current tire pressure. It also compares the readings to the recommended pressure levels stored in its memory.

Dashboard Display

The TPMS dashboard display provides the driver with real-time information about tire pressure. It may show the pressure of each tire individually or provide a general warning if any tire pressure falls below the recommended threshold. 

There could be multiple reasons why the tire loses pressure. One can get rid of these problems earlier when the TPMS warns and alerts about the low tire pressure.

What Happens When A Mercedes TPMS Goes Bad?

A Mercedes-Benz TPMS sensor can also fail. Here are a few signs of a bad tire pressure sensor:

  • A malfunctioning TPMS may incorrectly detect low or high tire pressure, leading to false warnings on the dashboard. 
  • In some cases, a failing TPMS may not provide any tire pressure warnings, even if the tire pressure is dangerously low or high. 
  • If the TPMS is not functioning properly, you may encounter difficulties when attempting to reset or relearn the system after replacing a tire or performing maintenance. 
  • It can lead to improper tire pressure, which can increase the risk of tire damage. Underinflated tires may wear unevenly and have reduced traction, while overinflated tires can become prone to blowouts or excessive wear in the center of the tread.

That said, it is not safe to drive with a bad tire pressure sensor. Therefore, you should always replace these sensors with new ones to avoid any problems. You may find a tire pressure warning light, here’s how to reset this warning in TPMS sensors.

How To Reset TPMS Sensor Light in Mercedes-Benz

When you drive your Mercedes and identify a warning light, you will need to follow the steps to reset the tire pressure light:

  • First, press the button on your steering wheel and select the TPMS option
  • Now check the tire pressure on the dashboard 
  • Open the petrol lid and check the optimal tire pressure required in your Mercedes-Benz
  • Now check the tire pressure in each wheel using a tire pressure gauge
  • Fill the pressure if it is low
  • Now reset the TPMS using the steering wheel buttons
  • After that, it will mention the accurate TPMS or send the signal to drive for a few minutes
  • Drive the car for a few minutes or one mile to reset the TPMS light

That wraps the complete information about the Mercedes-Benz TPMS sensors. Ensure buying new car TPMS sensors when the old one fails.
