How to reset triangle with exclamation point BMW

The triangle with an exclamation point on a BMW dashboard is a general warning indicator. It appears when the vehicle detects a condition that requires the driver's attention. This warning symbol usually comes with a message on the iDrive screen or instrument cluster explaining the issue. It is not a specific fault code but a general alert.

Common reasons for this warning include a door, hood, or trunk not fully closed, low windshield washer fluid, low fuel level, low tire pressure, worn brake pads, a due service reminder, or a malfunction in stability systems like DSC or DTC.

Step one is to check the control messages.

Start the car or turn the ignition to the on position without starting the engine. Use the iDrive controller to access the menu. Go to Vehicle Info, then to Vehicle Status, and open Check Control Messages. Read the listed messages and follow the instructions, such as closing doors, refilling washer fluid, or inflating tires. Once the issue is fixed, the triangle warning usually disappears automatically.

Step two is to reset service reminders if the triangle is related to maintenance.

With the ignition on and engine off, press and hold the odometer reset button on the instrument cluster for a few seconds. The service menu will appear. Use the stalk or BC button to scroll through service items. When you reach the one related to the triangle warning, press and hold the button to reset it. Confirm the reset if prompted. After a successful reset, the warning will no longer display.

Step three is to reset the tire pressure monitoring system if the warning is due to tire pressure.

First, check and correct the tire pressures according to specifications. Then go to the iDrive system, enter Vehicle Status, and select Flat Tire Monitor. Choose the Reset option. After driving for a few minutes, the system will recalibrate and the warning will clear.

If the triangle warning remains after taking these steps, it may require diagnostics using a BMW scanner tool such as Carly, BimmerLink, or ISTA. Some complex system warnings, like brake or transmission faults, cannot be cleared manually and must be resolved by a professional mechanic.

In summary, the triangle with exclamation mark is a general warning. Use the iDrive system to find the cause. Resolve the issue, and the warning should disappear. Some items require manual reset, especially service reminders or tire pressure. If the warning does not clear, scan the vehicle with a diagnostic tool or consult a technician.
