    Could be a number of things and you need to have a shop scan the codes to determine exactly what turn the check engine light on and you can find a shop here http://repairpal.com/directory?address=06470&car_brand_names=Mercedes-Benz

    both of my E-Classes have had their crankshaft position sensor fail. In my 98 it would not give a check engine light. My 2002 just started acting up (hard engine start while hot) and spit out the CPS code.
