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.
How much time does it take to reset a BMW’s tire pressure monitor?
When the tire pressure light blinks three times, release pressure on the TPMS reset button. To allow the sensors to reset, start the automobile and let it run for 20 minutes.
How is the tire pressure monitoring reset?
Without starting the car, turn the ignition to the “On” position. Once the tire pressure light has flashed three times, release pressure on the TPMS reset button. Start the car, then wait for the tire pressure sensor to reset for roughly 20 minutes.
On a 2018 BMW, how do you reset the tire pressure light?
Click car, vehicle status, tire settings, and tire pressure monitor from the home menu. Select to do a reset when the automobile is stopped and the engine is running. For the reset to be completed, you will need to take a little drive.
On a BMW x3, how do you reset the low tire pressure indicator?
Set your tire pressure to the recommended level and according to the driver door jamb. While running your engine, leave your car in park. At the front of the center console, push and hold the red arrow-depicted reset tire pressure button. TPM light will go off and then come back on if button is held down.
Why, when my tires are fine, BMW, is the tire pressure light on?
What it means: Your vehicle’s tire pressure will be too low and the BMW tire pressure monitoring system (TPMS) will notify you. When air pressure is 25% below the usual suggested pressure for your BMW model, the warning light turns on. Low tire pressure could put your BMW at danger for tire failure, excessive tire wear and tear, handling issues, and decreased fuel efficiency.
What to do if it comes on: Turn off your car and check the pressure in each tire if the TPMS light comes on when you start it. Ensure that the tires are inflated to the optimum pressure. The recommended tire pressure is printed in your owner’s handbook or on a placard inside the driver-side door of your car.
Find a gas station with air pumps, check the tire pressure, and add air as necessary if the TPMS indicator illuminates while you are driving. The TPMS light will also come on if your tire suddenly flattens as a result of damage. Pull over right away and inspect your tires if you see this light and experience a difference in how your car handles. Many BMW automobiles come with run-flat tires already mounted from the manufacturer with no spare tire. If so, move cautiously to a BMW service center in the area. You will need to hire a tow truck if you have fitted aftermarket tires that are not run flats.
It often denotes a TPMS malfunction if the indicator glows and flashes. The first step is to check the pressure in each of your tires once more and add air if needed. Your best option is to take it to a qualified BMW mechanic for diagnosis if the TPMS light is still on after adding air.
Note: Extreme weather changes can have an impact on tires, particularly in the colder winter months. It’s a good idea to inspect your tires each month.
What actions are required to turn off the light: If your tire pressure is too low, you should fill them up with air and then reset your TPMS (see the directions in your owner’s manual to do this). If this doesn’t work, you’ll need to visit your local BMW repair shop for an accurate diagnosis.
After changing your tires, how do you reset the sensor?
Turn the key to the “on” position with the car off, but don’t let it run. When the Toyota tire pressure sensor blinks three times, hold down the TPMS reset button until it stops blinking. Start the car, then let it run for 20 minutes to let the sensor reset. Under the steering wheel is typically where you’ll find the TPMS reset button.
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.
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.
Why won’t my tire pressure warning light turn on?
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 much time does a tire sensor take to reset?
Start the car, then wait for the sensor to refresh for around 20 minutes. 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 your owner’s manual. Tires should be inflated to the recommended pressure, then completely deflated.
What is the cost of repairing a tire pressure sensor issue?
What is the price of a new TPMS sensor? Depending on the type of car, the cost to replace the TPMS sensors might be between $50 and $100 each.
