The yellow triangle is different from the red triangle, which indicates a more serious issue that requires immediate attention.
The yellow triangle can be triggered by a variety of issues, including problems with the vehicle’s engine, transmission, brakes, or suspension.

Issues with the brakes, such as worn brake pads or a faulty brake sensor, can also trigger the yellow triangle.
In addition to these issues, the yellow triangle can also be caused by problems with the vehicle’s electronic systems, such as a faulty navigation system or a malfunctioning entertainment system. In some cases, the yellow triangle may be triggered by a minor issue, such as a loose gas cap or a faulty tire pressure sensor. Regardless of the cause, it is always best to have the problem checked and diagnosed by a qualified BMW technician as soon as possible.

First, make sure that the issue that triggered the yellow triangle has been resolved. If the issue was caused by a minor problem, such as a loose gas cap, you may be able to reset the yellow triangle by simply tightening the gas cap and restarting the engine.
If the issue was more serious, you may need to have the problem diagnosed and repaired by a qualified BMW technician. Once the issue has been resolved, the technician can reset the yellow triangle using a specialized tool.

In most cases, it is safe to drive your BMW with the yellow triangle illuminated, but it is not always recommended. If the yellow triangle is accompanied by a message on the dashboard display, it is a good idea to read the message and take any recommended action.
