The most common reasons a 2019 BMW M550i xDrive 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 M550i xDrive 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 M550i xDrive?

To effectively diagnose the tire pressure warning light issue in your 2019 BMW M550i xDrive, begin with a thorough check of the tire pressure in all four tires using a reliable tire pressure gauge. It's essential to compare the readings against the manufacturer's recommended levels, which can typically be found in your owner's manual or on a sticker located inside the driver's door jamb. Next, inspect each tire for any visible signs of damage, such as punctures, cuts, or bulges, as these can lead to pressure loss and trigger the warning light. If the tire pressure is correct and no damage is found, proceed to reset the tire pressure monitoring system following the instructions provided in your owner's manual, as this can sometimes resolve temporary issues. However, if the warning light remains illuminated after these steps, it may indicate a more serious problem, such as a faulty sensor or a leak, at which point consulting a mechanic or a BMW service center for a professional diagnosis is advisable. By following this diagnostic approach, you can systematically address the issue and ensure your vehicle's safety and performance.

What could be causing the tire pressure warning light to stay on in a 2019 BMW M550i xDrive?

When the tire pressure warning light stays illuminated in a 2019 BMW M550i xDrive, it is essential to identify the underlying issues to ensure safe driving. The most common reason for this warning light is low tire pressure, which can result from natural air loss or punctures; therefore, regularly checking and maintaining the recommended tire pressure is crucial. Another possibility is a malfunctioning tire pressure sensor, which may not provide accurate readings if it is faulty. Additionally, the batteries in these sensors have a finite lifespan and may need replacement if they are depleted. Calibration of the sensors is also necessary, as improper calibration can lead to incorrect readings and trigger the warning light. Lastly, a malfunction within the tire pressure monitoring system, such as wiring issues or problems with the control module, may require diagnostic testing to pinpoint and resolve. Addressing these potential problems promptly is vital for maintaining the vehicle's safety and performance.

How urgent is it to address the tire pressure warning light on a 2019 BMW M550i xDrive?

Addressing the tire pressure warning light on a 2019 BMW M550i xDrive is an urgent matter that should not be overlooked. Ignoring this warning can lead to serious safety risks, as improper tire pressure can significantly affect the vehicle's handling and stability, particularly in critical driving situations. Additionally, neglecting to check and adjust tire pressure can result in uneven tire wear, which not only shortens the lifespan of your tires but also increases the likelihood of a blowout while driving. Furthermore, maintaining the correct tire pressure is essential for optimal fuel efficiency; under-inflated tires can lead to higher fuel consumption, costing you more at the pump. Lastly, the Tire Pressure Monitoring System (TPMS) is designed to alert you to potential issues, and ignoring the warning light may indicate a malfunction that requires immediate attention. Therefore, it is crucial to check your tire pressure and make necessary adjustments as soon as the warning light appears to ensure your safety and the longevity of your vehicle.
