What Should You Do When Your BMW Brake Light Comes On During Driving?

While driving a BMW, you may notice that your brake light comes on and stays on. This is a sign of something wrong with your vehicle’s braking system. It doesn’t necessarily mean you should panic, though – unless the light stays on after you come to a complete stop and switch off the engine. In this case, it could indicate serious damage or malfunctioning components that need immediate attention.

It’s Always Wise To Pay Attention To Your Vehicle Dashboard Lights And Warnings

The brake light is a warning light that comes on when there’s a problem with your braking system. It might be caused by something as simple as driving through water and getting it into the brake fluid, or it could indicate serious issues with your brakes. It’s always important to pay attention to your vehicle dashboard lights and warnings, so if you see this one come on, take it seriously and get your car checked out by an auto repair professional immediately.

If your BMW brake light comes on during driving, it is first pulled over and switched off the ignition. This is important because you don’t want to keep driving with a faulty brake system.

  • If a warning light has come on while you’re driving, it’s important that you stop as soon as possible, turn off the engine, and take a look at what might be wrong before continuing.
  • When you get out of the vehicle, look at your front and back tires. If they are worn down too much, this could be causing the problem—it may be time for new brakes! Look at all four wheels as well; if any of them are bent or cracked in any way, that could also contribute to the issue (although it would be rare).
  • Next up: check under your car for leaks or drips from anywhere near where fluid usually leaks out (for example, from underneath an axle). Check around all wheel wells for any signs of fluid pooling or tracking onto other parts of your car, either on top or underneath it.
  • Check the brake fluid level: if it is low, top it up.
  • Test the brakes for responsiveness: if they seem to be working fine, you may need to replace the brake light.
  • Clean the brake light assembly: if it’s dirty, this could be causing the problem.
  • Replace the brake light bulb: this is often the cause of a brake light coming on during driving.
  • Take your BMW to a mechanic: if you can’t determine the cause of the problem, have a professional take a look.
  • You don’t want to end up in an accident! In addition, even if there isn’t any visible damage or other problems, it’s always best not to drive when your car’s lights are flashing—especially if they indicate something serious (like brakes).

In most cases, you can drive your vehicle, even when the brake light is on. Avoid sudden stops or driving at high speeds.

If you believe that your vehicle’s brakes are not working properly and it has a BRAKE LIGH ON message in the Driver Information Center (DIC), do NOT drive it until:

  • You have safely parked it somewhere safe outside of traffic and then turned off the ignition; OR
  • A licensed mechanic has checked out your car and determined it is safe to drive.


The BMW brake light can alert you to some issues. It’s important to know when it comes on and what you should do about it. If your BMW braking system is not working properly, take it in for service as soon as possible.
