A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing.

Frequently Asked Questions
Why is the Brake Pad Wear Light on in my BMW X4?
The Brake Pad Wear Light illuminates on a BMW X4 when the vehicle detects a condition in the related system that is outside its normal range. The exact reason can vary from something as minor as a loose connection to a component that needs replacing, which is why reading the stored trouble codes is the reliable way to know for certain.
Can I keep driving with the Brake Pad Wear Light on?
For a BMW X4, a steady amber Brake Pad Wear Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
How much does it cost to fix the Brake Pad Wear Light on a BMW X4?
Repair cost for the Brake Pad Wear Light on your BMW X4 depends entirely on the root cause. Because the same symbol covers cheap and expensive faults alike, a proper scan-based diagnosis is the best money you can spend — it turns a guess into a precise, fair quote.
Will the Brake Pad Wear Light reset itself on a BMW X4?
Sometimes the Brake Pad Wear Light on a BMW X4 clears on its own once the condition that triggered it no longer exists — for example after several good drive cycles. More often, though, the light stays on until the underlying fault is repaired and the code is cleared, so treat a self-clearing light as a reason to still investigate.
