Field notes from Marcus Vale, ASE-Certified Master Technician

Frequently Asked Questions

Why is the Fog Light Indicator on in my Mercedes-Benz AMG GT?

On a Mercedes-Benz AMG GT, the Fog Light Indicator comes on because a monitored value crossed a threshold the car considers abnormal. It could be a simple, inexpensive cause or a genuine fault — the only way to be sure is to scan the vehicle and interpret the codes rather than guess from the symbol alone.

Can I keep driving with the Fog Light Indicator on?

For a Mercedes-Benz AMG GT, a steady amber Fog Light Indicator 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 Fog Light Indicator on a Mercedes-Benz AMG GT?

Cost varies widely because the Fog Light Indicator can stem from several causes on a Mercedes-Benz AMG GT. Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour. Getting the specific trouble code first is what lets a shop quote accurately instead of estimating blind.

Will the Fog Light Indicator reset itself on a Mercedes-Benz AMG GT?

Occasionally, yes — a Mercedes-Benz AMG GT can extinguish the Fog Light Indicator by itself when the monitored value returns to normal. But a light that keeps coming back is a clear sign of an unresolved issue that needs a proper diagnosis rather than repeated resets.
