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.

The TPM System’s reset
Reset the system each time a tire’s inflation pressure has been adjusted, a wheel has been replaced, or a tire has been replaced.
Lightly press button 1 on the indicator lever several times up or down until the relevant symbol and the word RESET show up in the display.
Press button 2 for approximately 5 seconds to display the reading at the top right.
Start your car. The corrected inflation pressures will be used as nominal values after a few minutes of driving. Upon successful completion of the system reset, the indicator lamp turns off.
Contrary to popular belief, a flat tire monitor is not the same as a tire pressure monitor (FTM). The actual inflation pressure in the tires is not measured by an FTM system.
As you drive, the FTM compares the speeds of the different wheels and employs the Dynamic Stability Control (DSC) and Antilock Braking System (ABS) sensors to detect a tire pressure loss. The rolling circumference and, consequently, the rotation speed of the afflicted wheel alter when there is a pressure drop. When the system notices this, a flat tire is reported.
The FTM is no longer used in vehicles going to North America since it is a less reliable monitoring system. Additionally, TPM systems call for the installation of a sensor (integrated with the valve stem) on every wheel. Wheel sensors are not used by FTM systems.
Your tires are NOT properly filled using the Tire Pressure Monitor (TPM) device. As stated on the Wheels and Tires page, TPM isn’t obliged to sound an alert until the tire pressure is 25% below the recommended level. That is hardly enough to support the vehicle’s maximum load and well below the pressure needed for safe driving. The TPM system is not meant to be a monitor to make sure your tires are inflated properly, but rather as a last-minute warning before impending tire failure.
Should your tire pressure light be reset?
You should first check the pressure in your tires. Remember to check every tire, including your spare. It should reset your tire pressure indicator as long as your tires are correctly filled and fall within the acceptable range for your car.
You might need to fix your tire, have your TPMS examined, or try one of the following if the light is still on after setting the tire to the appropriate PSI:
- Drive for ten minutes. Attempt to reach a speed of 50 MPH.
- A TPMS reset button or process may be available in your car’s vehicle control center. Examine a professional or consult your owner’s manual (highly recommended).
Important information: If the pressure isn’t set to the car’s specifications, resetting the TPMS with a button or the vehicle control center may have negative effects.
Les Schwab experts are familiar with the reset processes to complete the task if those solutions don’t work. Each sensor can be programmed into the computer system of your car using tools we have. The next time you start your car or truck, or a few miles down the road, the indicator light ought to go out once your tires are correctly inflated or repaired.
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.
How can I turn off the tire pressure warning light?
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.
Why won’t my tire pressure warning light turn on?
Try the following if your TPMS light is still on after you have inflated your tires to the recommended pressure: 10 minutes at a speed of 50 mph would be plenty. When you start the car again, the TPMS light should not be on because the tire sensors should have been reset.
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.
Why did I rotate my tires, and now my tire pressure sign is on?
Every time I rotated the tires in one of my cars, a light indicated that I had a flat tire. Even if everything was in order when I checked my pressures, the light wouldn’t go off. This led me to question whether rotating your tires will affect the TPMS sensor that is integrated into the wheels.
Although tire rotation confuses your car, it doesn’t necessarily mess with your TPMS sensors. The manufacturer has set the sensors to operate at specific pressure levels. Different target psi values are used for the front and rear tires. Your car rotates its tires while checking the pressure in the rear tires’ TPMS sensor while checking the pressure in the front tires. This can cause your automobile to assume a tire is under- or over-inflated and will cause a misleading warning light to appear.
I’ll answer that query in this essay. I’ll go through TPMS sensors and tire rotations in more detail as well. I’ll conclude by explaining how to rotate your tires without damaging your TPMS sensors.
How can my BMW 3 Series be reset?
The mechanic will reset the computer in your BMW after the service is complete so it can record your mileage and let you know when the car will need maintenance again in the future. However, the techniques listed below can help you if you maintain your own car but are unclear of how to reset the computer system.
- With the engine off, turn the key to the ON position.
- For TEN seconds, press and HOLD the ODOMETER button. It can be found at the Instrument Cluster’s extreme bottom LEFT corner.
- The dash screen will display FGSTNR along with a number. Your chassis number is this (See image example).
- The LAST FOUR numerals are added. Ex: 3+4+5+6= 18 (taken from the image above). Your UNLOCK CODE is going to be 18.
- Press and hold the ODOMETER button one more until the FGSTNR clearing area appears (you will still see numbers in the top section).
- Press the odometer button until the upper Menu area (entering code menu) reaches 19 after the bottom area has cleared; When you do, the text will appear at the bottom: Press the odometer button to enter your unlock code after turning the lock on (from the example above) This is seen in the bottom portion.
- The screen will appear as in the image above after a little period, at which point the menu will once again appear at the top. To access the number 21 menu, press the odometer button (also theentering code menu).
- On the screen’s bottom, it will say: RESET? To complete the reset, press the odometer button.
Your BMW’s computer has been restarted! The existing settings must now be added again, or new ones must be added.
**NOTE: Slowly repeat the procedures if you are unable to reset the BMW computer on your first attempt. If you’re still having trouble, ask the dealership for help or refer to your car’s owner’s manual.
When the tire pressure light is on, can I drive?
You should be able to find our store or an air pump if the light just came on and you need to get there. However, it is unsafe to keep driving while the light is on. This is why: When you drive your car with low tire pressure, you accelerate the premature and severe tire wear.
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.
What PSI should the tires on a BMW be?
To ensure a safe ride, you should check the tire pressure on your BMW. Although 32 PSI (pounds per square inch) is the recommended tire pressure for most BMW models, you should always double-check by examining the sticker on the inside edge of the driver’s door.
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.
Can over-inflated tires turn on the tire pressure warning light?
You most likely have a Tire Pressure Monitoring System (TPMS) installed if you drive a more recent vehicle. Your tires’ internal electrical TPMS system keeps track of their air pressure. The TPMS turns on a dashboard warning light if your tires are either under- or over-inflated. You need to have your tire pressure checked if the light is steady. You should have your TPMS examined if the light is flashing.
Visit one of our stores for a free tire pressure check if you notice the TPMS light. If you’re on the road, fill up your tires with air as soon as you can at a petrol station. unsure how much more to say? For further information, see How to Check Tire Air Pressure.
Don’t panic if the TPMS light illuminates or flashes after you install the spare if you need to change a tire. Nothing to worry about there; that’s merely the system’s way of letting you know it can’t locate a TPMS unit in the spare tire.
Accurate tire pressure is now possible thanks to TPMS. It automatically alerts you when the pressure is low, keeping you safer, preventing damage to your tires, and increasing your MPG.
