    Vehicle : Signum

    Trim : Design

    Engine : 1.9Cdti 150

    Year : 2004

    Default Should I get the EGR and DPF removed and mapped out?

    Hi, My 1.9CDTI 150 is going into MAS performance for a remap in the next couple of weeks. Do you guys think I should get the EGR + DPF removed and wrote out of the software? I know they both cause many problems so its kinda making sure they wont go in the future but is there any disadvantages of having them removed?

    Any comments greatly welcomed

    the only thing i would be careful of is there are rumours that they ma change the MOT so if youre meant to have a dpf and dont it could fail.

    i have just had mine cleaned and i am still very tempted to get it remapped and deleted but havent decided yet

    If you're keeping the car for a good length of time then have the dpf & egr mapped out, saves on heart ache later

    Ben ( MAS ) did mine a while back, taking the dpf off physically also gave me another 15bhp ( rolling road before & after ). Egr now blanked & oil catch can fitted so no more crap going into inlet. However as already said the rules have changed a little with dpf so if I were to do it again, I would leave the DPF in place physically but have a stright through pipe fitted through the middle of it to give the impression it's still a working unit :-)

    First of all it looks like you have a Signum? Unless it's an auto you won't have a DPF.

    The DPF, even when working 100%, does reduce the power that the cars engine can produce but the biggest reason to remove the DPF is usually because it keeps getting blocked. If the car does not regularly get driven on the motorway or on a fast A road for around 30mins then the DPF doesn't get cleared out properly and starts to cause issues. If this is the case I would be tempted to do something about the DPF.

    As mentioned above it's a little unclear as to whether your car will fail an MOT if you remove the DPF. One MOT test place I have been to has said they would fail the car another has said they wouldn't so who knows!?!?

    Maybe another option is to get the DPF regen cycle tuned. I don't know if MAS can do this but on the EDS remaps with the DPF they have tuned the DPF software so that it regens more often and under different conditions. So its far less likely to get blocked.

    Mine's a manual, it had a DPF.
    Why not put a straight through pipe right down the middle of the DPF to give the illusion of a fully working unit?
