Hi there, Just took delivery of a gorgeous 61 plate C180 Sport, Edition 125. My ECO Start/Stop works fine. But after about 4 or 5 stops, the Yellow / Green ECO indicator disappears from the dashboard display and then the green LED light on the ECO button (near the hazard lights) goes out. Then if I press the ECO button to turn it back on again, it doesn't work. However, if I physically turn off the engine and then re-start again, it works ok, but again, after about 4 or 5 engine stops, the same thing happens again. Just wondering if you have spotted this on your car? Or is it a problem with just my car...?
