Just to follow up on the issue. The new brake pads works fine but the yellow icon on the dashboard still show solid yellow light indicating the brake pad wear sensor is on. I asked some people about that. Some say, like the last messge above, the sensor is making contact with metal. Can the brake pad wear sensor be remove without taking the new brake pads off? The mechanic I spoke to said sometimes. Is it safe to drive the mercedes with the yellow light on even though with new brake pads on all four wheels? I still have not taken the mercedes to the shop at this time because I am getting all kinds of different answers to my issue. I want to make sure to make the right decision before I decide what to do. Any comments/feedback is greatly appreciated.
