it would help if you identified year and model of your w202, but in general you need not change coils unless they fail... I suggest changing all filters and fluids, including transmission and fuel filter, and the differential fluid.... bosch platinum plugs, new wires... change coolant, and possibly the thermostat if it hasn't recently been changed....Originally posted by audiophile
