The tire pressure monitoring system (TPMS) is an essential safety feature in modern vehicles. It helps drivers keep track of the tire pressure and alerts them if there is a loss of pressure in any tire. This feature is particularly critical in high-performance cars like the 2014 BMW 4 Series, where tire pressure can impact performance and safety. In this article, we will discuss how the tire pressure monitoring system works on the 2014 BMW 4 Series.
How Does the Tire Pressure Monitoring System Work on 2014 BMW 4-Series?
The TPMS on the 2014 BMW 4 Series is a direct tire pressure monitoring system. It uses sensors located in each tire to monitor the air pressure in real-time. These sensors transmit data to the car’s onboard computer, which then alerts the driver if there is a significant deviation from the recommended pressure.
Components of the TPMS
The tire pressure monitoring system on the 2014 BMW 4 Series consists of four main components:
Tire pressure sensors: These sensors are mounted on each tire’s valve stem and measure the air pressure inside the tire.
Receiver module: The receiver module receives data from the sensors and sends it to the onboard computer.
Onboard computer: The onboard computer processes the data from the receiver module and alerts the driver if there is a significant deviation from the recommended pressure.
Warning light: The warning light on the dashboard illuminates if there is a significant deviation from the recommended pressure in any tire.
How to Reset Tire Pressure Light
Be sure all tires are at recommended pressures. (Always adjust pressure when tires are cold)
Have the car ON or RUNNING.
Select the MENU button.
Select VEHICLE INFO.
Select VEHICLE STATUS.
Select PERFORM RESET.
Select PERFORM RESET again.
How Does the TPMS Alert the Driver?
The TPMS on the 2014 BMW 4 Series alerts the driver in two ways:
Warning light: If the pressure in any tire falls below a certain threshold, the warning light on the dashboard illuminates. The light stays on until the driver corrects the tire pressure or until the issue is resolved. (The threshold is usually about 10% of the recommended pressure. So if pressure should be 35 PSI, and pressure drops 3.5 PSI or more, the TPMS warning light will turn on)
Tire pressure display: The driver can also access the tire pressure display through the car’s infotainment system. This display shows the pressure in each tire and alerts the driver if there is a significant deviation from the recommended pressure.
Common Causes For Tire Pressure Light to Turn On:
Low tire pressure due to a punctured or leaking tire
Incorrect tire pressure due to overinflation or underinflation
Temperature changes causing a drop in tire pressure
Faulty tire pressure sensors
Battery failure in the tire pressure sensor
Wheel alignment issues causing uneven tire wear and pressure discrepancies
Damage to the valve stem or tire bead causing air leakage
Replacement of one or more tires causing a mismatch in tire pressure
Incorrect tire size installed on the vehicle
Electrical or wiring issues in the tire pressure monitoring system.
When to Reset Tire Pressure Monitoring System:
After rotating or replacing tires
After adjusting tire pressures
When changing tire pressure sensors
After changing the tire size or installing new wheels
After plugging or patching a tire
If the tire pressure warning light remains on even after inflating the tires to the recommended pressure
When performing maintenance or repairs on the tire pressure monitoring system or related components
If the battery in the tire pressure sensor dies and the sensor is replaced
After any modification that may impact the tire pressure or tire pressure monitoring system.
FAQ's
Q. How often should I check my tire pressure?
A. It is recommended to check your tire pressure once a month or before any long trips.
Q. Can the TPMS sensors be replaced?
A. Yes, the TPMS sensors can be replaced. However, it is recommended to replace them with OEM sensors to ensure compatibility and accurate readings.
Q. Can the TPMS be recalibrated?
A. Yes, the TPMS can be recalibrated if the tire pressure sensors have been replaced or if the tire pressure has been adjusted.
Conclusion
The tire pressure monitoring system is a vital safety feature in modern cars, including the 2014 BMW 4 Series. It helps drivers keep track of the tire pressure and alerts them if there is a loss of pressure in any tire. In this article, we have discussed how the TPMS works on the 2014 BMW 4 Series, its components, and benefits. If you own a 2014 BMW 4 Series or any other car with a TPMS, it is essential to keep the tire pressure within the recommended range to ensure your safety and performance.
