    All,

    I have a W209 CLK '05 320CDi. At idle the rev's are stable, but when driving at a constant speed you feel the car hesitate and the rev's fluctuate. I’ve only notice this recently. The vehicle has been serviced recently but could this be a fuel filter issue or something more sinister?

    Any help would be greatly appreciated.
    TIA

    Get a software update on the engine control unit first. MB dealer can do this.

    Doesn't this sound a bit like the EGR issue the Vito 3.0L are having.?
