The most common reasons a 2019 Mercedes-Benz S560 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 2019 Mercedes-Benz S560 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.

What steps should I take to diagnose the tire pressure warning light issue on my 2019 Mercedes-Benz S560?

When diagnosing the tire pressure warning light issue on your 2019 Mercedes-Benz S560, it's essential to adopt a systematic approach that prioritizes simpler solutions before moving on to more complex diagnostics. Begin by manually checking the tire pressure of all four tires with a reliable tire pressure gauge, ensuring that each tire is inflated to the recommended levels outlined in your vehicle's manual. Next, conduct a thorough visual inspection of the tires for any signs of damage, such as punctures, cuts, or bulges, and look for any foreign objects lodged in the tread that could be causing a leak. If the tire pressure appears normal and the tires are in good condition, attempt to reset the Tire Pressure Monitoring System (TPMS), as temporary fluctuations can sometimes trigger the warning light. If the light remains illuminated after these steps, it may be time to consult a certified mechanic or dealership for a more in-depth diagnosis, as they have the specialized tools necessary to identify potential issues, including malfunctioning TPMS sensors that may require replacement. By following this structured diagnostic approach, you can effectively address the tire pressure warning light issue and ensure your vehicle's safety on the road.

What could cause the tire pressure warning light to stay on in a 2019 Mercedes-Benz S560?

When the tire pressure warning light stays illuminated in a 2019 Mercedes-Benz S560, it is essential to identify the underlying issues that may be causing this alert. The most common reason is low tire pressure, which can be easily resolved by checking and inflating the tires to the recommended levels. If the tire pressure is adequate, the problem may lie with a faulty tire pressure sensor, which can malfunction and fail to provide accurate readings. Additionally, the sensors may need recalibration, particularly after tire rotations or replacements, a process that can usually be performed at a service center. Electrical issues within the tire pressure monitoring system can also lead to a persistent warning light, requiring diagnostic testing to determine the exact cause. Furthermore, it is important to inspect the tires for any visible damage or slow leaks, as these can also trigger the warning light. Timely attention to these potential issues is crucial for ensuring the safety and performance of your vehicle; if the warning light remains on after addressing these common problems, seeking assistance from a qualified mechanic is recommended for further diagnosis and repair.

What immediate steps should be taken to address the tire pressure warning light that remains on in a 2019 Mercedes-Benz S560?

When the tire pressure warning light remains illuminated in your 2019 Mercedes-Benz S560, it is crucial to act swiftly to ensure your safety and the vehicle's performance. Start by checking the tire pressure in all tires, including the spare, using a reliable gauge to confirm they meet the manufacturer's specifications. If you find any tires underinflated, inflate them accordingly to prevent uneven wear and potential blowouts. Additionally, inspect each tire for visible damage, such as punctures or bulges, which could compromise their integrity. After making necessary adjustments, reset the Tire Pressure Monitoring System (TPMS) through the vehicle's onboard menu, and take the car for a short drive to allow the system to recalibrate. If the warning light persists, it is essential to consult a qualified mechanic, as ongoing issues may indicate deeper problems within the TPMS that could affect your vehicle's safety and performance. Addressing these concerns promptly not only enhances your driving experience but also helps prevent costly repairs down the line.
