Hey everyone, just wanted to check if anyone experienced anything similar on their F3x card:
I haven’t checked the brakes visually yet, will do it over the weekend. Did anyone see this happen before? |

i believe we have 2 stage wear sensors on our brake pads, first stage determines your estimated wear rate so it gives you miles estimate (the 22k you saw before), but once the 2nd stage is reached it basically tells you have only a limited amount of miles left before they need to be changed. if i had to guess your sensor reached the 2nd stage and is giving you 3000 miles of driving left before you need to change them.
now whether that is accurate or not, you'd need to visually check your pads, its possible the sensors are wrong or it could be something else entirely.

The 'first stage', which estimates the mileage/time to a pad change, is a pure guess. The car doesn't know the condition of the pads. The 'second stage', tripping of a sensor, happens when that pad is on its last legs. The problem is that there are only two sensors, but there are eight pads. The only way to know what's going on is visual inspection of all eight pads on a regular basis. You can't trust what it says in iDrive. If a sensor is tripped, causing a dashboard warning and mileage count down, get it done right away.
I did have to replace my first set of pads at 11k miles, even though the iDrive said they were good to 40k miles, due to inadequate lubrication of the pads at the factory, which caused them to fail to retract. |
