Problems after full mercedes service
We recently bought a 1990 300CE and thought we would do the proper thing and take it to our local mercedes garage for a full maintainance service. The garage rang up to say that there was a slight misfire which we may not have noticed but they would look at. 3 days later after trying everything (new coil pack, new leads, plugs replaced in service, new injectors etc) they suggest a problem with the valves or head gasket which to fix would be very expensive. We opted to leave this as our understanding from them was that the problem was un-noticable (we certainly hadnt noticed any misfiring before the service took place) We have now got the car back and it runs terribly, misfiring at idle and low load, but running normally at high speed. What have they done to our car to cause this problem during its service? Any ideas would be greatfully recieved.
