hello guys i have a 2000 e220cdi.I changed my fuel filter about 400 miles ago with a non gen one.all has been fine but i now have a problem with rough idling.i have now fitted a gen merc filter but the problem still exsists,i am wondering if i have disturbed the filter outlet pipe,does anyone know how to take this off and check the o ring?this pipe has a two pronged plastic clip.
any suggestions appreciated
