The newer BMW models contain a feature known as a tire pressure control display that determines whether the tires have the right quantity of air in them. This operates by increasing the measured number of tire revolutions as the radius of the car tire decreases owing to less air.
Since most tires have different designs when compared to one another, the issue arises when switching from winter to summer tires and vice versa and causes the tire pressure control display on the on-board computer to activate. Fortunately, BMW automobiles have a reset button for the tire pressure control display.
You can use the iDrive system to verify the status of your car if the tire-pressure warning symbol displays in the instrument cluster or in alerts.
Select My vehicle from the main menu, then tap Vehicle status, and then check the icon for the Tire Pressure Monitor to turn it on. Your tires’ current pressure is shown on the tire pressure meter. If you got a warning, it advised you to reset the device by selecting Perform reset on the TPMS information screen.
After the reset, if all tires display green, the pressure is accurate. Incorrect pressure is indicated by a red accent on a tire.

Why, after filling my tires with air, is my tire pressure light still on, BMW?
If you’ve inflated your tires, but the air pressure warning light continues to flash, your tire pressure monitoring system is malfunctioning or you have a gradual leak. A bright TPMS warning light indicates a problem with a tire pressure sensor, assuming there isn’t a leak in your tire. One of them might be damaged, the lithium-ion battery might be dead, or the TPMS itself might have an internal problem. You’ll need to get your Tire Pressure Monitoring System repaired in any of these scenarios.
Quick Tip: Recheck the tire to ensure it is inflated to the correct air pressure if the TPMS warning light illuminates again after you have inflated it. Low tire pressure indicates an air leak, which requires repair or tire replacement.
Why won’t my tire pressure warning light turn on?
If your tires are properly inflated yet the warning light continues to illuminate, you may have a leak or a TPMS issue in one or more of your tires. To determine if a tire has a leak is not difficult. Simply double-check the air pressure in each of your tires with your tire gauge. If all of the tires have the proper air pressure, one or more tire pressure sensors are likely to be at fault, necessitating repair work on your tire pressure monitoring system. You’ll need to replace or repair the tire if you notice that one or more of your tires’ air pressures have fallen.
My tire pressure is fine, so why won’t the light go off?
When the TPMS warning light illuminates, proceed with caution. This indicates that at least one of your tires may be at least 25% under-inflated.
*The simplest way to get the most accurate reading is to check the tire pressure before you drive on it when the tire is “cool.” If your TPMS light is on, first check that you have correctly reset your TPMS by following these instructions.
Will my TPMS light automatically turn off if I fill my tires with air after it illuminates?
Several minutes after reinflating the tires to the prescribed pressure, the TPMS light ought to go out.
What happens if I adjust the tire pressure but the light on my tire pressure gauge still doesn’t go out?
The only place that can fix a computer issue that causes the TPMS warning light to turn ON and flash ON for one second and OFF for three seconds is the dealership service center. When the TPMS warning light illuminates and remains on, one or more tires may have low tire pressure. The light ought to go out once the tire is inflated to the recommended tire pressure listed on the door placard. Always check the pressure in all of your tires because one or more of them may not be at the proper pressure.
How do you remove the low tire pressure alert?
When the tire pressure light blinks three times, release pressure on the TPMS reset button. Start the car and let it run for 20 minutes to let the sensor reset. Under the steering wheel is normally where you’ll find the reset button for the tire pressure monitor. If you can’t find it, consult the owner’s manual for your vehicle.
I have a low tire pressure light on. Can I drive?
Is Driving Secure? You should be able to continue driving safely for a few more miles until you can add air if your tire pressure is only slightly low. Extremely low tire pressure can cause tires to fail. This could lead to a blowout, which could be quite deadly.

Is it possible to disable the tire pressure sensor?
Yes, it is possible to disable your tire pressure monitoring device using a smart, non-intrusive approach. You only need to use an emulator created to get around the TPMS. The TPMS bypass emulator is a tiny box-shaped gadget containing technology that allows you to “switch off” your tire pressure monitoring system.
What tire pressure level is dangerously low?
I’m aware that keeping my tires filled is crucial, but how strictly should I adhere to this rule? For instance, on occasion when it’s chilly in the morning, my tires may appear to be a bit low. Can I take my car to work? How depressurized may my tires be?
In less than two minutes, find out if your auto insurance is being overcharged.
You are entirely correct! Maintaining optimum tire pressure has many advantages, including improved gas mileage and a longer tire life. If you’re wondering how low is too low for tire pressure, you’re not alone. It’s also typical for tire pressure to fluctuate with cold weather.
The lowest tire pressure that you may drive on safely is 20 psi, though even that is not advised. Driving on a tire that has less than 20 psi of air pressure is dangerous for your car. You should add air if your tires are this low.
Tire pressure recommendations typically range from 32 to 35 psi. Your tire pressure will change by around one psi for every 10 degrees that the temperature changes. Therefore, if it’s 80 degrees outside in the afternoon and your tires are inflated to 32 psi, the pressure may drop to 28 psi if it’s 40 degrees outside in the morning.
That’s alright! Although 28 psi is less than the advised pressure, your automobile won’t suffer. When you start driving, friction warms your tires and increases pressure. They all return to their proper locations as the day progresses.

Why are my tires full but my tire light is on?
defective TPMS sensor The TPMS is not working properly if you have used a pressure gauge to ensure that all four tires are inflated to the recommended level recommended by your car manufacturer, but every time you start the vehicle, the pressure light comes on and stays lit.
Is a flat tire a result of low tire pressure?
Don’t ignore the tire-pressure warning light if it turns on; you might be getting a flat. A tire’s tendency to lose around a pound of air pressure every month and a pound for every 10 degrees of temperature drop can cause low pressure, as can leaks.
Should the TPMS be reset after purchasing new tires?
After changing or rotating your tires, or after adding new sensors, you should always reset your TPMS. Even after you have inflated your tires, some sensor manufacturers advise restarting the device. By teaching the primary TPMS system to identify the sensors in their new locations, resetting the TPMS is frequently referred to as retraining the system. TPMS reset procedures vary from vehicle to vehicle and typically involve a specific sequence of ignition and pedal actions, a configuration change in your dashboard menu, or the use of a TPMS Reset Tool.
Without a reset button, how do you reset a TPMS?
The system must be put in relearn mode in order to reset the light. Make sure the tire pressures are all set evenly and according to the specifications first. To prevent the battery from going out, you might need to first connect a battery charger on low. All accessories must be turned off. After turning the key to the “On” position for 20 minutes with the engine off, drive the car at a speed of at least 16 mph for at least 7 minutes. The light will turn off once the relearn operation is complete. If the light does not turn off, the system needs to be fixed. Tire pressure sensors may need to be replaced because they can start to malfunction after 5 or 6 years of use.

How long should the tire light be on when driving?
Low tire pressure makes the situation worse because it is more difficult to gain traction and roll ahead. Under these circumstances, avoid driving with low tire pressure for more than 40 miles or more than 30 minutes.
What distinguishes TPMS from low tire pressure?
Remember that your TPMS does not substitute for regular tire pressure checks. Although it is a device that can help notify you when pressure is low, a tire may deflate below the recommended level of inflation long before the TPMS warning light illuminates. When the tire pressure is either too low or too high, the TPMS light illuminates.
