The most common reasons a 2019 BMW M5 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 BMW M5 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 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 in my 2019 BMW M5?

To effectively diagnose the tire pressure warning light issue in your 2019 BMW M5, begin with a thorough check of the tire pressure in all four tires using a reliable tire pressure gauge. This initial step is crucial as it ensures that the tire pressure aligns with the specifications outlined in your vehicle's manual. Next, visually inspect each tire for any signs of damage, such as punctures, cuts, or bulges, and look for any foreign objects that may be lodged in the tread. If the tire pressure is correct and the tires appear undamaged, consider resetting the tire pressure monitoring system, as this can sometimes resolve temporary issues that trigger the warning light. However, if the warning light remains illuminated after these steps, it is advisable to consult a certified mechanic or dealership for a comprehensive diagnosis and necessary repairs. By following this diagnostic approach, you can systematically address the issue while ensuring the safety and performance of your BMW M5.

What could be causing the tire pressure warning light to remain on in a 2019 BMW M5?

When the tire pressure warning light remains illuminated in a 2019 BMW M5, it can be attributed to several common problems that DIY enthusiasts can investigate. First and foremost, checking the tire pressure in all four tires is crucial, as low pressure is the most frequent culprit. If the pressure is adequate, the next step is to examine the tire pressure sensors; a faulty sensor may need replacement. Additionally, consider whether the sensors require recalibration, which can sometimes be done at home with the right tools, although professional assistance may be necessary for precise calibration. Electrical faults within the tire pressure monitoring system can also trigger the warning light, so inspecting the wiring and connections for any visible damage is advisable. Lastly, ensure that the sensors are clean and free from debris, as obstructions can interfere with their operation. By systematically addressing these potential issues, you can effectively troubleshoot the cause of the persistent warning light and maintain the safety and performance of your BMW M5.

What should I do if the tire pressure warning light on my 2019 BMW M5 stays on?

When the tire pressure warning light on your 2019 BMW M5 stays illuminated, it is essential to act swiftly to ensure your safety and prevent further complications. Neglecting this warning can lead to serious consequences, including diminished traction, increased tire wear, and the risk of a tire blowout, which could result in costly repairs or accidents. Begin by checking the tire pressure of all four tires using a reliable gauge, making sure they are inflated to the manufacturer's specified levels found in your owner's manual or on the sticker inside the driver's side door. If you discover any tires are underinflated, inflate them to the correct pressure, as both underinflation and overinflation can trigger the warning light. Additionally, conduct a thorough inspection of your tires for any signs of damage, such as punctures or bulges, which could compromise their safety. After adjusting the tire pressure, you may need to reset the tire pressure monitoring system, a procedure typically detailed in your owner's manual. If the warning light remains on after these steps, it is prudent to seek assistance from a qualified mechanic or BMW service center to diagnose any potential issues with the monitoring system. By addressing the tire pressure warning light promptly, you not only enhance your driving safety but also contribute to the overall health and longevity of your vehicle.
