The most common reasons a 2017 BMW 750i 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 2017 BMW 750i 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 are the initial steps to diagnose a persistent tire pressure warning light on a 2017 BMW 750i?

When faced with a persistent tire pressure warning light on your 2017 BMW 750i, start by checking the tire pressure in all four tires, ensuring they are inflated to the manufacturer's recommended levels, as low pressure is a frequent culprit. Next, inspect each tire for visible damage such as punctures or bulges that could lead to air loss. If the tires appear fine, attempt to reset the tire pressure monitoring system following the instructions in your owner's manual, as this can sometimes resolve the issue. To confirm accuracy, use a reliable tire pressure gauge to double-check the readings. Additionally, examine the valve stems for any signs of leaks or damage that might be affecting tire pressure. If these steps do not resolve the warning light, consulting the owner's manual for further troubleshooting guidance is advisable. Should the light persist despite these efforts, it may be time to seek professional assistance from a mechanic or dealership for a more thorough diagnosis.

What could cause the tire pressure warning light to stay on in a 2017 BMW 750i?

When the tire pressure warning light remains on in your 2017 BMW 750i, it can be frustrating, but understanding the common problems can help you diagnose the issue. One of the primary culprits is low tire pressure, which is easily checked with a tire pressure gauge. Ensure all tires are inflated to the manufacturer's recommended levels, as even a slight drop can trigger the warning light. If the pressure is adequate, consider the possibility of a faulty tire pressure sensor. These sensors can malfunction or require recalibration, which may necessitate professional assistance. Additionally, the sensor batteries can deplete over time, leading to communication failures with the vehicle's system. Inspecting the wiring and connections for any damage or loose ends is also crucial, as these can disrupt the tire pressure monitoring system. Lastly, if you've recently changed tires or had maintenance done, the system may need recalibration to provide accurate readings. By systematically checking these factors, you can effectively troubleshoot the persistent tire pressure warning light and ensure your BMW is safe and road-ready.

How urgent is it to address the tire pressure warning light on my 2017 BMW 750i?

Addressing the tire pressure warning light on your 2017 BMW 750i is not just a matter of convenience; it is a critical safety concern that demands immediate attention. Ignoring this warning can lead to severe consequences, including compromised vehicle handling and increased risk of accidents due to poor traction and stability. Low tire pressure can also accelerate tire wear, resulting in costly replacements and potentially leaving you stranded on the road. Furthermore, underinflated tires can significantly reduce your fuel efficiency, leading to higher fuel costs over time. The urgency to act is clear: by regularly checking and maintaining your tire pressure, you not only enhance your safety but also prolong the life of your tires and improve your vehicle's overall performance. Therefore, it is essential to respond promptly to the tire pressure warning light to avoid these risks and ensure a smooth driving experience.
