In order to respond to your inquiry, there are in fact two brake sensors—one on each front and rear wheel. The back sensor, as I recall, is on the right (passenger side). The front side’s side escapes me at the moment.
Rear brakes could be required. Since they are employed for traction control, stability control, electronic LSD, and other functions, they are the first to be worn.

Are there brake pad sensors in the BMW F30?
BMW 3 Series F30 Brake Pad Wear Sensors (2012+) When it’s time to replace the brakes, the driver is warned by the vehicle’s brake pad wear sensors.
Are sensors present in BMW brake pads?
Recent releases from numerous German manufacturers, notably BMW, have a two-stage pad wear sensor (See Figure 3). The driver can receive more information from these sensors than just a worn brake pad alert. They can actually calculate the remaining mileage of a brake pad.
How many braking sensors are there in a BMW?
One sensor is for the front and the other is for the back. Is your brake light illuminated on your dash? If not then you can reuse your old sensors but if you do you need to replace either one or both. There are two: one for the rear passenger and one for the front driver side.
How does a brake pad sensor for a BMW operate?
Electronic brake pad wear sensors are now installed in a wide range of contemporary vehicles, especially European vehicles. They inform you when it’s time to replace your brake pads with a brand-new set. But how do they function? And how frequently do they require replacement?
The conventional metal squealer tabs that are more frequently used in braking systems are replaced by electronic brake pad wear sensors. When the pads have reached the end of their useful life, these tabs continue to function by rubbing against the rotor. It alerts the driver that the brakes need maintenance by emitting a loud screech.
In addition to the scream, this has the drawback that most drivers tend to ignore the warning since they believe the sound will ultimately stop. Electronic brake wear sensors take care of this noise and provide a more precise indication of the remaining life of the brake pads.
Once the brake pad has worn sufficiently for the sensor to make contact with the brake rotor, the wear sensors are intended to break or complete a circuit. The dash will typically illuminate with a warning light when the brake pads need to be changed.
Basic brake wear systems typically implant a sensor inside the inner brake pad at each corner of the car. However, from vehicle to vehicle, the number of wheels with sensors and their positioning on the brake pad can differ. These systems merely have a wire loop that is conducting a little amount of current.
Brake wear sensors in the modern day have a few new tricks up their sleeves. Not only do they alert the driver when brake maintenance is necessary, but they can also predict how long your existing brake pads will last. These trick sensors work utilizing two resistor circuits running parallel at two depths, often known as twostage sensors. As the first resistive circuit breaks, the resistance in the sensor increases. In order to determine how much life is still left in your brake pads, this is utilized to collect data such as wheel speed, brake pressure, brake disc temperature, brake operation time, and mileage. This is typically shown in the information center of your automobile or as a warning light that changes color as the pad ages. The circuit becomes open when the second circuit is disrupted. This sets off the brake service indicator light, alerting you that it’s time.
Braking pad wear sensors are not reusable because they are made to break or complete a circuit by making contact with the brake rotor. With each change of brake pads, wear sensors for the brakes should be updated. To fit a variety of automobiles, Bendix offers brake pad wear sensors. For the majority of common makes, our Bendix Euro+ Brake Pads also include all required clips, shims, and sensors, so you’ll be ready for your upcoming brake pad replacement. At your next service, request Bendix brakes from your mechanic.
The majority of popular makes and models are guaranteed to fit with Bendix’s brake wear sensors. Visit to determine if your local Bendix stockist has brake sensors that will work with your vehicle.

The accuracy of the BMW brake pad sensor
It is very accurate if installed properly since it needs to be changed when the minimum level is reached because it wears out. You shouldn’t be concerned until your car shakes noticeably when you brake.
Are new BMW brake sensors required?
The “brake” light on your dashboard or iDrive system is controlled by your BMW brake pad sensor, which also informs you of the remaining life of your brake pads. The sensor is mounted to the brake pad; as soon as the brake pads are completely worn down, the sensor’s tip breaks, tripping the wire and turning on the dashboard light. The brake pad sensor error codes are as follows when using an OBD scanner:
5, 5, 6, 5, 14, 5, 15, and 6F12
Every time you change your brake pads, you should also replace the brake pad sensor. The sensor does not need to be changed every time, but failing to do so could lead to erroneous readings of the amount of life left in your pads and a persistent notification on your dash/iDrive system. The only way to get rid of the light once it appears on the dash is to either swap out the sensor or bypass it, which will stop it from reading the pad life.
Is the BMW brake sensor reusable?
Nope. If not carefully remove them and reinstall them, they only need to be replaced if they have been activated. Nope. Unless they have been activated, they merely need to be replaced; otherwise, carefully remove them and reinstall.
Are sensors present on each brake pad?
One corner of the car often has sensors in the front and back to measure the wear of the brake pads. Because the inboard brake pad normally wears out the quickest, the sensors are installed on it. For every inboard brake pad, there are more sensors on higher-end systems. Every pad may include a sensor on more exotic automobiles with carbon or ceramic rotors.
The sensor’s resistance value was known in earlier systems. A rectifier circuit in the instrument cluster sensed an open circuit when the resistance reached 2,000 ohms or above and turned on the light. Physical harm and corrosion at the connector are the most frequent causes of failure for these circuits.
In some systems, the sensors are connected in series. In this instance, when the circuit loop is disrupted, the system is unable to identify which brake pad has been overused. This can make open circuit diagnosis challenging. To pinpoint an issue, you must check for continuity at the connectors.
How many sensors measure brake wear?
This turns on the warning light that signals that the brakes need to be serviced. While many brake pad wear systems have a sensor on the inboard pad at each corner of the car, the exact number might vary based on the braking system’s design, from one to four.
Can the brake pad sensor be removed?
Except for the sensor that needs to be changed if the brake wear warning light is on, you actually don’t need to update the sensors. It will not light up on your dash if you simply cut off the plastic piece at the end and twist the two wires together, leaving it hanging.
Where are the braking sensors?
because the last thing that keeps you and your vehicle safe is a set of properly working brakes.

What is the price of a braking sensor?
Aftermarket pad sensors can cost anything from $5 to $100. Additionally, you should budget an additional labor expense of $70 to $100 if you decide to hire a professional brake work.
A new sensor can also cost more due to a number of factors, including:
- Make and model of the vehicle
- Brand and series of brake pad sensors
- Warranty for brake sensors
- Sensor pad length
- elements of worn sensors
- in which you reside
How much do brake repairs cost at BMW?
The cost of new brakes depends on your BMW model. Depending on the brake pad material, replacement brake pads can range in price from $150 to $300 per axle on average. Your brakes’ other components, including the rotors, may have been impacted by any prior damage to the brake pads.
What’s the mechanism of a brake pad wear indicator?
The wear indicator is a monitoring tool that alerts the driver as soon as the brake pad has worn down to its minimal thickness. This is typically two millimeters for disc brake pads. Depending on the brake system, either an electronic or an auditory wear indication may be used.
Why did my brake reset attempt fail?
The sensor was tripped, according to the alert. It must be replaced after being tripped in order to reset. Before a reset is feasible, you might also need to use an OBD diagnostic tool to clear the problem codes. You will unquestionably require a scan tool if you replace the sensor and try to reset, but it still states “reset impossible.”
