After replacing rotors and pads on 2003 Mercedes c230 how do you reset warning wear dashboard?

To reset the brake pad wear indicator on a 2003 Mercedes-Benz C230, you will need a diagnostic tool such as a Mercedes Star Diagnosis system or an equivalent OBD II scanner. Here are the steps:

Park your C230 and ensure the engine is off.

Connect the diagnostic tool to the C230's OBD II port, which is usually located under the dashboard on the driver's side.

Turn on the ignition, but do not start the engine.

Using the diagnostic tool, navigate to the Brake Wear section. The exact name of the menu might differ depending on the diagnostic tool.

Find the option to Reset Brake Pad Wear Indicator or something similar.

Select the "Yes" or "Confirm" option to reset the indicator.

Exit the diagnostic tool and turn off the ignition.

Start the engine, and the brake pad wear dashboard warning should be reset.

Please note that resetting the brake pad wear indicator does not mean that your brake pads are new or in good condition. If the brake pads were worn out when you replaced them, you will need to replace them again as soon as possible to ensure the safety of your vehicle.
