💡 Notes:

• If the reset does not work, your BMW might require a diagnostic tool (e.g., BMW ISTA, Foxwell NT510, or Autel) to reset the brake fluid service interval.

• A persistent warning light might also indicate low brake fluid, a faulty sensor, or air in the system—make sure these are ruled out.
