The most common reasons a 2016 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 tire 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 2016 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 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 in my 2016 BMW M5?

To effectively diagnose the tire pressure warning light issue in your 2016 BMW M5, start with the simplest solution: checking the tire pressure. Ensure that all tires are inflated to the manufacturer's recommended levels, as the warning light often activates when pressure drops significantly. Next, inspect the tire pressure monitoring system (TPMS) sensors, which are crucial for accurate readings; a malfunctioning sensor can lead to false alerts. Keep in mind that these sensors typically have a lifespan of five to seven years, so if your vehicle is approaching this age, consider the possibility of sensor failure. If you suspect a sensor issue, manually check the tire pressure with a reliable gauge and adjust as necessary. Should the warning light persist despite these efforts, it may be time to consult a technician for a more thorough diagnosis. By following this diagnostic approach, you can systematically address the issue, ensuring your BMW M5 remains safe and performs optimally on the road.

What could cause the tire pressure warning light to stay on in a 2016 BMW M5?

When the tire pressure warning light remains illuminated in a 2016 BMW M5, it can be attributed to several common problems that DIYers should be aware of. One frequent culprit is a malfunctioning tire pressure monitoring system (TPMS) sensor, which may have a dead battery or could simply be faulty. Additionally, extreme temperature fluctuations can affect tire pressure, causing the warning light to activate even if the tires appear adequately inflated. If you've recently replaced your tires, it's crucial to perform a TPMS relearn or reset, as failure to do so can result in the warning light staying on. Other potential issues include problems with the spare tire, a faulty TPMS module or electronic control unit (ECU), and various electrical malfunctions. By understanding these common problems, you can effectively troubleshoot and resolve the tire pressure warning light issue, ensuring your vehicle's safety and performance.

How urgent is it to address the tire pressure warning light on a 2016 BMW M5 that stays on?

When the tire pressure warning light on your 2016 BMW M5 remains illuminated, it is crucial to take immediate action. Ignoring this warning can lead to serious safety risks, including compromised handling and increased likelihood of tire blowouts, which can endanger both you and other road users. Additionally, the tire pressure monitoring system (TPMS) serves as an essential indicator of your vehicle's overall health; a persistent warning light suggests that there may be underlying issues that require attention. Common causes for the light staying on include underinflated or overinflated tires, as well as potential malfunctions within the TPMS itself. If adjustments to tire pressure do not resolve the issue, it may indicate a sensor problem that could hinder accurate monitoring in the future. Therefore, addressing the tire pressure warning light without delay is vital not only for your safety but also for the longevity and performance of your BMW M5.
