I did a search but came up with nothing.My grandpartents have a 99' S420. They took the car to the dealer to get it serviced, they did the service but didnt reset the service light. we took it back to the dealer but they wont reset it. well its not really I light, when I start the car there is a little wrench that shows in the digital display. can anyone tell me how to reset it. thanks

Did you perform a service on the car or just an oil change?
