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.
How can I disable the tire pressure indicator?
Turn the key to the “ON” position with the engine off, but do not start your car. When the tire pressure light blinks three times, release pressure on the TPMS reset button. Start the vehicle and let it run for 20 minutes to let the sensor reset.
Why does my tire pressure light come on even if everything is fine?
It’s likely that one or more of your tires have low air pressure if you see the tire pressure indicator turn on. However, even if your tires are in good condition, there are a number of things that could cause the sensors to go off, so you shouldn’t rely only on the data from the tire pressure monitoring system of your car.
Why is my tire pressure light still on even though I just inflated it?
The TPMS (Tire Pressure Monitoring System) is designed to notify you when a tire’s pressure is too low and may result in hazardous driving situations. If the indicator is on, your tires may not be properly inflated, which might result in premature tire wear and even tire failure. It’s critical to comprehend the value of appropriate tire inflation and how TPMS can prevent a potentially hazardous situation.
Both excessive and inadequate tire inflation can result in early tread deterioration and potential tire failure. Increased traction, early wear, and an inability to withstand impact from the road can all be effects of overinflation. The middle of the tread on tires with excessive air pressure may prematurely wear out. Underinflation, on the other hand, results in slow tire reaction, lower fuel economy, excessive heat buildup, and tire overload. The shoulders or tread edges of a tire that is underinflated will prematurely wear out on both sides.
Finding the TPMS indicator on your dashboard is straightforward if this is your first time hearing about tire pressure sensors. It is a light that has a horseshoe form with an exclamation point in the middle.
My tires are in good condition, so why is my low tire pressure sign on?
While the tires appear to be in good condition and the low tire pressure light is ON, you can:
- simply press a button to reset the machine and observe the results; or
- The sensors need to be changed since one or more of them are damaged.
After starting the vehicle, the low tire pressure warning light ought to turn on for a few seconds. The light ought to be turned off right away.
Drive your car, preferably to the closest gas station or tire shop, to check the air pressure in each tire if the low tire pressure warning light is still on.
Typically, a tire with an air pressure that is 10% to 15% low will turn on the warning light. The air pressure inside the tires also tends to drop in cold or icy conditions. Short trips in the car will warm up the tires and raise the pressure in them.
But if the low tire pressure warning light is still on and all the tires are adequately inflated and warmed up, move on to the next step.
Take this opportunity to get out the owner’s manual. The TPMS reset button may be found on the console or in the glove box, depending on the make and model of your car.
Here are the steps to take after finding the TPMS reset button:
- Don’t start the engine after turning the key to the ON position.
- For at least three seconds, press and hold the TPMS reset button before letting go. The system will switch off the warning light and produce a beep or other audible alert.
- To finish the reset process, start the engine and drive the vehicle for 30 to 1 hour at a minimum speed of 19 mph.
- It’s time to check or replace the TPMs sensors if the warning light comes back on.
- To get the system tested, drive to the nearest tire store or dealership.
If your car has TPMS, avoid making it a practice of resetting it every time the low tire pressure warning light comes on.
Your safety is considered during the system’s design. The pace of technological advancement means that the TPMS sensors get better with each new model. However, you should make it a practice to check the tire pressure each time you get in the car in order to get the most out of what you have.
Use a different method than the TPMS to check the tire pressure. A quick visual check is sufficient to establish the existence of a flat.
Here’s a helpful hint: just in case, always have a tiny tire pressure gauge in the glove box. You may check the real tire pressure with this straightforward gadget before the TPMS activates.
Take your vehicle to the shop so they can “re-learn” the sensor with a specific tool if your TPMS light is still on. These tools are available online, but they are not inexpensive. I would advise researching the Autel TS501.
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.
How soon after tire filling will the light turn on?
Tire pressure can be impacted by overnight temperature variations or by cold winter days. The low-pressure indicator may then display as a result of this. The pressure in your tires can change by up to 10 PSI when there are significant temperature changes between day and night.
After about 20 minutes of driving, the light may turn off on its own when the right inflation level stabilizes and the air in your tires warms and expands.
In any case, you ought to have your air checked immediately. Your tires are at least 25% underinflated, according to the TPMS light. This poses a risk to your safety, especially if the load is close to your vehicle’s maximum load capacity. There is a higher possibility of tire failure, degraded handling, and increased tire wear and tear. Your fuel economy may also suffer.
How is a tire monitor 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.
What is the cost of repairing a tire pressure sensor issue?
My Lexus’ tire sensor isn’t functioning. I’ve grown accustomed to relying on the low pressure indicator to warn me when my tires are having issues. How much does a tire pressure sensor repair cost?
In less than two minutes, find out if your auto insurance is being overcharged.
Tire sensors are an extremely useful diagnostic tool—so useful that since 2007, all car models have been required to have them! Fortunately, depending on your automobile type, repairing a tire pressure sensor normally costs between $80-$140.
The price of replacing a sensor can be reimbursed if your car is still covered by warranty. If you think this applies to you, check with your dealership.
Tire pressure sensors operate as follows:
- The sensors inform your car’s computer about the tire pressure by sending a signal. If the light comes on, make sure you check your tire pressure. It might indicate a leak or even that your tires are overinflated.
- In addition to making driving safer, properly inflated tires also yield improved gas mileage.

How can I tell if my BMW’s TPMS sensor is malfunctioning?
The TPMS warning light on your dashboard is the most typical sign of a damaged tire pressure sensor. Other oblique indicators like low tire pressure or inaccurate dashboard warnings may also be present.
A sensor is an electrical component, hence it has a chance to degrade over time. On top of that, the performance of the sensor might be significantly impacted by an erratic power supply, dirt, heat, and dust. When this occurs, the car undergoes certain noticable alterations.
Here is a more thorough list of the three signs that a tire pressure sensor is malfunctioning.
How much does a BMW TPMS sensor replacement cost?
Between $245 and $309 is the projected cost of labor, while $352 is the estimated cost of parts. Taxes and levies are not included in this range, nor are your particular model year or special location taken into account.
How long are the TPMS sensors made by BMW?
The Tire Pressure Monitoring System, which notifies you when a tire is dangerously low on air, typically uses TPMS sensors embedded in the tires to detect low tire pressure. The majority of TPMS sensors use internal batteries that cannot be changed to power them.
The lithium ion batteries in a TPMS sensor have a lifespan of 5 to 10 years. The duration of the TPMS sensor batteries is difficult to predict because it depends on how many radio frequency broadcasts the sensors send out. The amount of driving you perform over time and the conditions you drive in will affect the sensor battery life. The TPMS battery life is less affected by cold conditions than by warmer ones. When compared to continuous pace, stop-and-go traffic has a greater effect on TPMS battery life. This is due to the fact that sensors send out more radio frequency broadcasts as a vehicle changes its speed.
The system will issue a malfunction warning when a TPMS sensor’s battery runs out, which will be visible as a blinking TPMS light on your dashboard. After 60 to 90 seconds, the light may either continue to flash or turn solid. Be a repair appointment as soon as you can if you receive this warning, but also check the tire pressure in each tire right away to make sure you have safe inflation all around.
You can change each individual TPMS sensor separately if one of them malfunctions and needs to be replaced. The other sensors, on the other hand, are probably on the verge of failing as well if the failure was brought on by a dead sensor battery. You might wish to proactively replace all the sensors so you have brand-new sensor batteries all around when you take into account the time and hassle of taking your car off for a sensor replacement.
