    I have Cummins ISX 475 hp on my Volvo
    When I start the engine just a little black smoke comes out from exhaust pipe, then After I start driving the BLACK SMOKE pours a lot for the first 20 minutes especially on going uphill, then after 20 mins driving no more smoke at all...
    Any suggestions, please?

    Do you think the EGR needs to be replaced?

    I think EGR and VGT needs to be tested with Insight software first
