Inability to clear pad wear service alert. (2014 F20)

[spiezen]

I successfully used the concealed menus to initiate a reset of the brake fluid. However, my attempt to do the same procedure for the front pads yielded a "unsuccessful" outcome, despite the initial indication that a reset was really feasible.

Earlier today, I encountered the activation of the brake warning message, about one month subsequent to the completion of brake maintenance.

Is it necessary to replace the brake worn cables as well?

The Ancel BM500 handheld scanner encounters a failure while performing a CBS reset.

Perform a reset procedure while ensuring that the handbrake is disengaged.

The proposed solution is ineffective.

I discovered a technique on a different online platform:

BMW aims to install a new sensor during pad replacements in order to prevent the need for this action. However, a workaround to circumvent this involves briefly bridging the contacts on the wear sensor connection and thereafter performing a reset. After completion, the sensor may be reconnected.

I intend to do this task on the following day; nevertheless, I am perplexed as to why the warning did not manifest immediately subsequent to the installation of the new brake pads, but rather after a distance of 500 miles.

Did the brake pads exhibit a low level of wear when you replaced them?
In BMW vehicles, the sensors operate in a two-stage manner. When the first stage of the sensor becomes worn out, there is no visual indication in the form of a light, but the iDrive counter decreases. Subsequently, an indicator of service is often received following the completion of around 500 kilometers. When the second stage is in operation, it illuminates the orange pad light on the instrument panel.

The item in question is not significantly worn and I am unable to recall if I had consulted the Idrive webpage. The red brake sign and red triangle are consistently shown, along with a notification about the activation of the nanny driving mode.

Upon recollection, it became apparent that the vehicle required replacement discs. Consequently, I proceeded to install new pads concurrently. The previous sanitary pads exhibited around 50% wear.

It is likely that a modification of the sensor will be necessary in order to initiate a reset. I attempted to inspect the back end of my spouse's vehicle and found that the sensor seemed to be in satisfactory condition. However, despite my efforts to reset it, I had difficulties in achieving the desired outcome. I was required to modify the sensor.

[spiezen]

It is likely that additional ones will be required, and I will provide an update on if the aforementioned 'trick' was successful.
Thank you for your response.

In the event that one has difficulty in resetting the front brake pad wear indication and then receives a brake warning message, it is plausible that the wear sensors, namely the cables, have been activated or have incurred damage. It is recommended to do an inspection of the brake wear sensors and consider replacing them as a means of addressing the problem.

 

[spiezen]

Thank you for your response. I have placed an order for a pair of sensors; however, when inspecting the pads one month ago, they seemed to be in satisfactory condition.

I am personally experiencing the same issue.
The front lot was recently modified, prompting me to attempt the aforementioned suggestion.
