With the ignition on, Press the end of the wiper stalk until miles to service appears on the dash screen.
Now, press and hold the mileage reset button on the instrument binnacle for more than 5 seconds, it will start to flash. Let go
This will reset your miles to service to the factorysetting and get rid of the flashing spanner !
Hope this helps a few people.
If you mean the spanner symbol & message such as ‘change oil soon’ just scroll through your trip computer as you do when you zero your trip mileage when you fill up with petrol.
(press top button of right hand stalk).
Scroll through trip mileage/ averages etc until you get to the change oil message and then clear it the same way you clear your trip mileage by holding the button in until the message flashes & clears.
When a service is needed based on the car’s mileage or time since the last service, the display screen on a Mercedes C230 will notify you. The display screen is located within the speedometer on the instrument panel. Mercedes mechanics will reset the Service B notification light after the service is performed. If you performed the service, you need to reset the light yourself. Service B includes an oil and filter change, a tire rotation and other maintenance checks.
