The most common reasons a 2018 Mercedes-Benz GLE63 AMG S tire pressure warning light stays on are a leaking tire, a wheel that no longer holds air, or a faulty tire pressure monitoring system.
  • Tire Leaking Air: A puncture, valve stem issue, or rim damage can cause a tire to leak air, leading to loss of pressure.
  • Wheel Leaking Air: A puncture or damage to the tire or rim can cause air to leak, resulting in a loss of tire pressure.
  • Tire Pressure Monitoring System: A malfunctioning tire pressure monitoring system can be caused by faulty sensors or a dead battery in the sensor units.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2018 Mercedes-Benz GLE63 AMG S tire pressure warning light stays on?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

When a tire pressure monitoring sensor fails, the tire pressure monitoring system control module will recognize a loss in communication and turn on the warning lamp which indicates the failure. This is most often the case. However, the tire pressure monitoring sensor may also fail by reporting incorrect tire pressures. This could cause a flat tire to go unrecognized, or a properly inflated tire to signal a low or high tire pressure warning.

When a relearn is needed, for any reason, the TPMS warning light will illuminate, and many vehicles will display a message relating to the TPMS system being inoperative or loosing communication. It is important to keep a watchful eye on tire pressures when this system is having issues because there is no warning available for underinflation or overinflation of the tires.

Wheels offer very few symptoms, but these symptoms should never be ignored. Visible cracks on the wheels may appear, especially after hitting a large bump, Most often, this will also be accompanied by loss of air from the tire on that wheel. Also, vibration in the steering wheel is very common when the tire is out of balance, and improper wheel nuts or bolts can cause creaking and popping noises to develop. Again, there are very few symptoms, but they should not be ignored.

The only symptoms of a TPMS control module failure are failing to alert the driver of underinflation or overinflation of one or more tires, failure to communicate with the body control module or TPMS sensors, or erroneously reporting incorrect tire pressure.

The only symptoms requiring diagnosis for the tire pressure monitoring system warning lamp is if the warning lamp has illuminated while the tires have correct air pressure, or if the air pressure for the tires is out of specification and the warning lamp is off. This is because the overwhelming majority of cases where the TPMS lamp illuminates is due to the change in ambient temperature.

How do I diagnose a persistent tire pressure warning light on a 2018 Mercedes-Benz GLE63 AMG S?

To effectively diagnose a persistent tire pressure warning light on your 2018 Mercedes-Benz GLE63 AMG S, start by checking the tire pressure in all four tires, ensuring they are inflated to the manufacturer's recommended levels. This simple step can often resolve the warning if the pressure is low. Next, visually inspect each tire for any signs of damage, such as punctures or bulges, which could be causing the alert. If the tires appear to be in good condition, proceed to reset the tire pressure monitoring system as outlined in your owner's manual; this can sometimes clear false warnings. Additionally, examine the tire pressure sensors for any visible damage or malfunction, as these components are crucial for accurate readings. If, after these steps, the warning light remains illuminated, it may be time to consult a certified mechanic who can utilize specialized diagnostic tools to identify and rectify more complex issues within the tire pressure monitoring system. By following this methodical approach, you can efficiently troubleshoot and potentially resolve the tire pressure warning light concern on your vehicle.

What could be causing the tire pressure warning light to stay on in a 2018 Mercedes-Benz GLE63 AMG S?

When the tire pressure warning light remains illuminated in a 2018 Mercedes-Benz GLE63 AMG S, it can be attributed to several common problems that DIYers can investigate. First and foremost, checking the tire pressure in all four tires is essential, as low pressure is the most frequent cause of the warning light. If the pressure is indeed low, inflating the tires to the recommended levels may resolve the issue. Additionally, it's important to inspect the tires for any visible damage, such as punctures or leaks, which could be contributing to the loss of pressure. If the tire pressure appears normal, the next step is to consider the possibility of a faulty tire pressure sensor. These sensors can malfunction, leading to inaccurate readings and triggering the warning light. In such cases, recalibrating the sensors may be necessary to ensure they are functioning correctly. Furthermore, electrical faults within the tire pressure monitoring system, such as wiring issues or blown fuses, can also cause the light to stay on. Lastly, if the warning light appears during colder weather, it may simply be a natural drop in tire pressure due to temperature changes. By systematically checking these factors, DIY enthusiasts can effectively diagnose and potentially resolve the issue with the tire pressure warning light.

What immediate actions should be taken if the tire pressure warning light remains on in a 2018 Mercedes-Benz GLE63 AMG S?

When the tire pressure warning light remains illuminated in your 2018 Mercedes-Benz GLE63 AMG S, it is crucial to act promptly to avoid serious safety risks and potential damage to your vehicle. Ignoring this warning can lead to compromised handling, increased tire wear, and even blowouts, which can endanger you and other road users. Start by checking the tire pressure in all four tires with a reliable gauge, ensuring they meet the manufacturer's specifications found in your owner's manual or on the door jamb. If you discover any discrepancies, adjust the pressure accordingly—overinflated tires can cause a harsh ride and uneven wear, while underinflated tires can negatively impact fuel efficiency and handling. Additionally, visually inspect your tires for any signs of damage, such as cuts or bulges, as these issues may necessitate tire replacement for safe driving. After making the necessary adjustments, don't forget to reset the Tire Pressure Monitoring System (TPMS) to clear the warning light. If the light persists despite your efforts, it is essential to consult a qualified mechanic or an authorized Mercedes-Benz service center to diagnose any underlying problems. Taking these steps not only ensures your safety but also helps maintain the performance and longevity of your vehicle.
