The most common reasons a 2019 BMW 650i Gran Coupe 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 650i Gran Coupe 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 2019 BMW 650i Gran Coupe?

To effectively diagnose the tire pressure warning light issue in your 2019 BMW 650i Gran Coupe, begin with the simplest and most straightforward approach. Start by checking the tire pressure in all four tires using a reliable tire pressure gauge, ensuring that the readings align with the recommended levels found in your vehicle's manual. This initial step is crucial, as incorrect tire pressure is a common trigger for the warning light. Next, conduct a thorough visual inspection of each tire for any signs of damage, such as punctures, cuts, or bulges, and look for any foreign objects lodged in the tread that could be causing a leak. If the tire pressure is correct and the tires appear undamaged, proceed to reset the tire pressure monitoring system as outlined in your manual; this can often resolve temporary issues that may have caused the warning light to activate. However, if the warning light remains illuminated after these steps, it may indicate a more complex problem with the tire pressure monitoring system itself. In such cases, it is advisable to consult a certified BMW mechanic or dealership for a comprehensive diagnosis and repair, ensuring your vehicle's safety and performance are not compromised. By following this diagnostic approach, you can systematically address the issue while minimizing unnecessary complications.

What could be causing the tire pressure warning light to remain on in a 2019 BMW 650i Gran Coupe?

When the tire pressure warning light remains on in your 2019 BMW 650i Gran Coupe, it’s important to identify the underlying issues to ensure your vehicle's safety and performance. The most common reason for this warning light is low tire pressure, which can be exacerbated by temperature fluctuations, particularly in colder weather. Regularly checking and maintaining your tire pressure at the recommended levels is essential. If the tire pressure is adequate, the problem may lie with a faulty tire pressure sensor that could require replacement or recalibration. Additionally, the batteries in these sensors can wear out over time, leading to communication failures with the vehicle's monitoring system. It's also wise to inspect the wiring and connections associated with the tire pressure monitoring system for any signs of damage or loose connections, as these can prevent accurate readings. If you've recently had tire changes or maintenance, the system may need recalibration to function correctly. By addressing these common issues, you can effectively troubleshoot the persistent warning light and maintain the safety and reliability of your BMW.

What immediate steps should be taken to address the tire pressure warning light on a 2019 BMW 650i Gran Coupe?

When the tire pressure warning light illuminates on your 2019 BMW 650i Gran Coupe, it’s crucial to act promptly to avoid potential safety hazards and costly repairs. First, checking the tire pressure is essential; underinflated tires can lead to poor handling, increased tire wear, and even blowouts, which pose serious risks while driving. Use a reliable tire pressure gauge to measure the pressure in all four tires, ensuring they meet the specifications outlined in your owner's manual or on the sticker located inside the driver's side door jamb. If you find any tires are below the recommended pressure, inflate them accordingly to restore optimal performance. Additionally, inspect each tire for visible damage such as punctures or bulges, as these issues can compromise your safety and may require immediate repair or replacement. Once you’ve addressed any pressure discrepancies and inspected for damage, resetting the Tire Pressure Monitoring System (TPMS) is the final step to ensure the warning light turns off. This process can typically be completed through your vehicle's onboard computer system, as detailed in the owner's manual. By taking these immediate actions, you not only enhance your vehicle's safety and performance but also prevent further complications that could arise from neglecting tire maintenance.
