I just bought a '02 S430 and i was messing around with my instrument cluster display. I ended up resetting the display to factory settings which meant everything went to german. i fixed that but now it says i'm late on my annual maintenace by 139000 miles ( which is how much miles is on the car) how would i reset the warning messages?

Rofl, you must be black trying to get new gauges for your benz? Hey the Benz is not a civic, if you dont know what you doing, dont mess with it

Go to the dealer and check with them, they people will help u about the same.
