What the Hill Descent Control Light Means on a BMW 6 Series

How Urgent Is the Hill Descent Control Light?
How worried should you be? For the Hill Descent Control Light on a BMW 6 Series, the urgency is low. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing.

Cataloguing these symptoms is not busywork; each one narrows the list of likely causes and helps a technician zero in on the real fault instead of replacing parts on a hunch.
