Mercedes C240 check engine light reset?

one way is to disconnect the batt and let the car sit for over 30 min but then again you will need the code for the radio and all that stuff but this is only a quick fix it could last a 100,000 miles or it could last you till the car is warmed up depending on the problem with your car... I would ask a MB tech before doing anything like this but it is a cheater system you can use.. but it may have its risks... Its up to you to find out before trying this way you could just screw your self out of a car!
