I've been driving a Mercedes-Benz C200 for several years and have encountered the issue of the maintenance light not turning off a few times. After the last service, I tried resetting it according to the manual: turn off the engine, wait a few seconds, switch to the ACC position, use the steering wheel buttons to enter the service menu, and hold the reset button, but the light still remained on. I was really anxious at the time. After researching, I found out it might be due to outdated software or a sensor malfunction. I tried disconnecting the negative terminal of the battery for a few minutes and reconnecting it; after the system rebooted, the light went off. If that doesn’t work, it could be because the maintenance data wasn’t logged or there’s an electronic bug. Later, I learned that the maintenance light design in the Mercedes-Benz C200 is quite sensitive. During reset, you must ensure all settings are synchronized, and sometimes a professional diagnostic tool is needed for a forced reset. It’s important to remind the technician to test the reset function immediately after servicing to avoid minor issues accumulating and affecting daily use. In short, don’t panic—try the simple steps a couple of times, and if it still doesn’t work, schedule a check-up at the dealership for potential software or hardware issues.
