Before we dive into the reset process, it’s crucial to understand why this warning light might appear on your BMW’s dashboard. The triangle with an exclamation point typically signifies a fault in the vehicle’s safety systems, such as the ABS (Anti-lock Braking System) or the DSC (Dynamic Stability Control). It can also indicate issues with your tire pressure or brake fluid level. Resetting it without addressing the underlying problem is a temporary solution and should be done cautiously.

If you’ve ever been driving your BMW and noticed a triangle with an exclamation point symbol illuminated on your dashboard, don’t panic. This warning light is there to alert you to a potential issue with your vehicle. While it’s essential to address the problem, you can often resolve it yourself by performing a simple reset. In this article, we’ll walk you through the steps to reset the triangle with an exclamation point on your BMW.

Step 1: Park Your BMW Safely:

Before resetting, ensure your BMW is safely parked, and the engine is turned off. Safety should always be a priority when dealing with vehicle-related issues.

Step 2: Locate the OBD-II Port:

To reset the warning symbol, access your BMW’s On-Board Diagnostics (OBD-II) port. This port is typically located beneath the dashboard, near the driver’s seat. Refer to your owner’s manual for the exact location if you need clarification.

Step 3: Connect an OBD-II Scanner:

An OBD-II scanner is a crucial tool for this process. Plug the scanner into the OBD-II port, ensuring a secure connection.

Step 4: Turn on the Ignition:

Turn the ignition key to the “on” position without starting the engine. This step is essential for the scanner to communicate with your BMW’s computer system.

Step 5: Access the Scanner’s Menu:

Use the scanner’s interface to access the menu and select the “Clear Codes” option. This action will clear any fault codes triggering the warning symbol.

Step 6: Confirm the Reset:

Once you’ve selected “Clear Codes,” the scanner will prompt you to confirm the reset. Confirm the action to proceed.

Step 7: Turn Off the Ignition:

After the reset, turn off the ignition and disconnect the OBD-II scanner.

Step 8: Wait a Moment:

Wait for a moment before starting your BMW’s engine. This gives the system some time to recalibrate.

Step 9: Start the Engine:

Start your BMW’s engine and observe the dashboard. The triangle with an exclamation point symbol should be gone if the reset resolves the issue.

Step 10: Drive and Monitor:

Take your BMW for a short drive to ensure the warning symbol does not reappear. If it does, there may be an underlying issue that requires professional attention.


Resetting the triangle with an exclamation point on your BMW can be a straightforward process when done correctly. However, it’s essential to remember that this action should only be taken after ensuring your vehicle’s safety systems are in proper working order.
