Does your BMW have a tire pressure warning light on? Utilize the steps below to learn how to resolve the issue.
When tire pressure is too low, the BMW tire pressure monitoring system (TPMS, TPM, FTM) is intended to warn the driver. When the tire pressure is 20% below the prescribed pressure, the tire pressure warning light turns on; to turn it off, make sure the tires are properly filled.
The TPM or TPMS light (yellow tire symbol with exclamation point) and a warning message on the Drive Display, along with an audible sound, alert the driver to low tire pressure when a BMW detects a flat tire.
There is a problem with the tire monitoring system if the TPM or TPMS light flashes.
A 20% tire pressure decrease is detected by a BMW Tire Pressure Monitoring System, which then activates a TPM warning to notify the driver. This technology may also go by the names Flat Tire Monitor or FTM on a BMW.
You can be seeing a TPM failure or inactive errors even though the tire pressure is accurate because:
- The TPMS sensor is broken.
- The RDC module is broken
- external obstruction

Just a friendly reminder that the valve transmitter batteries need to be replaced in roughly 8 to 10 years. This appears as a tire pressure indication that repeatedly fails.
If you have access to a tire bead breaker, you can do these things yourself. each takes roughly 30 minutes. Clamp the tire portion near to the valve after breaking the bead. Remove, swap out, and then reinstall the transmitter and valve.
Recommendation: If your original metal valves are still in working order, use these rather than the cheap plastic valves that are sometimes provided with transmitters. or get new metal ones.
I completed all four at once since if one battery dies, the others will follow quickly.
TPM (RDC) Sensors with a Defect
The tire pressure is measured by TPM (RDC) sensors on the wheels. If one or more of them is broken, it sends the module incorrect information. The onboard computer is prompted to display an error message and/or switch on the TPM system dashboard warning light once the module perceives that as a defect.
RDC sensor replacement is a challenging and delicate task. If you don’t have the necessary skills or equipment, you might want to consider having a certified mechanic work on your vehicle.
What does TPM on a BMW mean?
The four mounted tires’ tire inflation pressure is monitored by the Tire Pressure Monitor (TPM) system using tire pressure sensors that are affixed to the tires. The technology alerts the user if one or more tires’ inflation pressure has significantly decreased.
What results in TPMS failure?
A TPMS issue could be any of the following: a TPMS sensor whose battery has run out and it is no longer working. a weak or failing battery that is causing the TPMS sensor to operate erratically. Due to an antenna or wiring issue, the TPMS module is not getting a signal from one or more sensors.
How is TPMS malfunction fixed?
When the tire pressure light blinks three times, release pressure on the TPMS reset button. For the sensors to reset, start the car and let it run for 20 minutes. The button to reset the tire pressure monitor is under the steering wheel.
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.
Can you operate a vehicle with a TPMS issue?
No, it is not safe to drive with the TPMS Light on. It indicates that one of your tires is either under- or over-inflated. The recommended tire pressure for your vehicle can be found in the owner’s manual or on a sticker on the door, trunk, or fuel door. This may result in excessive tire wear, perhaps result in tire failure, and result in a blowout that is hazardous to you and other motorists on the road. For detailed instructions on how to check your TPMS system, make sure to consult your owner’s manual. Different manufacturers may have altered how their TPMS lights activate.
How much does a BMW TPMS sensor replacement cost?
Best in Automotive Repair Replacement tire pressure monitor control modules for BMW 328i models typically cost between $597 and $661. Between $245 and $309 is projected to be the cost of labor, while $352 is the cost of the parts.
What occurs if TPMS sensors are not replaced?
Customers who ask you to turn off their TPMS light just and leave the underlying problem unattended can put you and your business at unnecessary risk. Without addressing the problem, you are breaking the NHTSA’s “make inoperative” clause, which makes shops legally obligated to disable the TPMS. It is your duty to let the customer know this and to decline service if they don’t want the problem handled properly.
It is strongly advised to replace all sensors at once if a single sensor has reached the end of its useful life. When one sensor fails, the others are likely to follow suit quickly, just like with headlights. The same holds true for replacing an impact sensor or damaged valve stem. Your consumers should be aware of this since it will assist you give their vehicle the finest care possible. They also find it convenient.
The TPMS sensors must always be reactivated and calibrated for drivers who change their tires as the seasons change. If you don’t do this, the car’s TPMS won’t function properly and could turn on the TPMS light.
In what location is the TPMS sensor?
Where is the location of the tire pressure sensor? It is affixed to the interior of the rim from inside the tire. The tire pressure sensor is a little cylinder that you can see if you take the tire off the rim.
How can I activate the TPMS light?
Till the tire pressure light blinks three times, press and hold the TPMS reset button. Press the button again to start the vehicle. Within twenty minutes, the light ought to turn off. While the car is off, cut the positive battery cable.
The TPMS button is not present.
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.
Can I change the TPMS sensors on my own?
Rubber-stemmed, snap-in TPMS sensors are just as simple to change as regular valve stems. No unique equipment is required. However, hex nut stems must be precisely torqued to a specified value using a TPMS valve stem tool or an accurate inch-pound torque wrench.
Why are my tires fine but my TPMS light is on?
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.
What is the price of a new TPMS sensor?
Depending on the type of car, the cost to replace the TPMS sensors might be anywhere from $50 and $100 per.
Because servicing TPMS needs additional parts, tools, and labor, TPMS-equipped tires are slightly more expensive to maintain than non-equipped tires. Every time a tire is removed from the vehicle for maintenance or replacement, the TPMS valve service kit, which consists of the valve core, (sealing) cap, nut, and grommet (stem seal), needs to be replaced. On most automobiles, the service kit is between $5 and $10 per wheel. The TPMS system needs to be checked and reset, which takes additional time and a special TPMS programming tool.
A service pack should be used to replace the sealing components of the sensor, which comprise the cap, valve core, grommet, nut, and any other accessory included in the service pack, according to Schrader(r), a producer of original equipment TPMS sensors. The integrity of the TPMS sensor and valve is guaranteed by replacing the service pack components.
TPMS are in my automobile. I haven’t had my repair shop service it yet. What should I anticipate when I arrive?
- Checking the system’s sensors and TPMS for appropriate operation
- Any component of your TPMS sensors that is malfunctioning should be repaired or replaced.
- Your vehicle’s computer will need to “relearn” how to place the TPMS sensors by doing this.
- After the tire service is finished, make sure your TPMS system is functioning properly.
What happens if I have an additional set of wheels and tires (for snow tires or unique wheels)?
You can get a spare pair of tires or wheel assemblies fitted with a set of replacement sensors. Your TPMS installer will be able to relearn the new sensors to the vehicle computer after the extra set of tires or wheel assemblies are attached to the vehicle. The sensors will need to be relearned to the vehicle computer when the original set of tires or wheel assemblies are reinstalled on the vehicle.
