The most common reasons a 2015 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 2015 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 2015 BMW M5?

To effectively diagnose the tire pressure warning light issue in your 2015 BMW M5, start with a manual check of your tire pressures using a reliable gauge. This initial step is crucial as it allows you to determine if the tire pressure is indeed below the recommended levels, which is a common trigger for the warning light. If you find that the pressure is off, adjust it by inflating or deflating the tires to meet the manufacturer's specifications. If the warning light persists after correcting the tire pressures, it may indicate a malfunction in the Tire Pressure Monitoring (TPM) system itself. In this case, it’s important to address any TPM issues promptly, as they can lead to inaccurate readings and potentially unsafe driving conditions. Regularly checking your tire pressure can help prevent future alerts and ensure optimal tire performance. If you are unable to resolve the issue through these steps, it may be necessary to consult a professional service center for a more thorough diagnosis and repair of the TPM system.

What could cause the tire pressure warning light to stay on in a 2015 BMW M5?

When the tire pressure warning light remains illuminated in a 2015 BMW M5, it can be attributed to several common problems that DIYers can investigate. One frequent culprit is a malfunctioning tire pressure monitoring system (TPMS) sensor, which may be due to a dead battery or sensor failure. Additionally, natural air loss from tires, punctures, or other forms of damage can lead to incorrect pressure readings, triggering the warning light. It's also important to consider that aging sensors may provide inaccurate data, especially if they have been exposed to harsh environmental conditions. If you've recently changed or rotated your tires, failing to reset the TPMS can keep the warning light on, as the system needs to recalibrate to the new tire positions. Furthermore, issues with TPMS programming can also cause persistent alerts, indicating that the system may require a reset or relearn procedure after tire replacement. Addressing these issues promptly is crucial for maintaining vehicle safety and performance, so if the light remains on despite checking tire pressure, further investigation into sensor functionality and system programming may be necessary.

How urgent is it to address the tire pressure warning light on a 2015 BMW M5 that stays on?

When the tire pressure warning light on your 2015 BMW M5 remains illuminated, it is imperative to take immediate action. Ignoring this warning can lead to serious safety risks, as improper tire pressure significantly affects vehicle handling and increases the likelihood of tire blowouts. Additionally, driving with incorrect tire pressure can compromise your car's performance, resulting in suboptimal handling and a less enjoyable driving experience. Beyond safety and performance, neglecting this warning can shorten the lifespan of your tires, leading to costly replacements sooner than necessary. Furthermore, maintaining the correct tire pressure is essential for fuel efficiency; under-inflated tires create more rolling resistance, causing your vehicle to consume more fuel. Lastly, delaying action could result in further damage to both the tires and the tire pressure monitoring system, leading to more expensive repairs down the line. Therefore, it is crucial to check your tire pressure promptly and address any discrepancies to ensure a safe and efficient driving experience.
