    Vehicle : vectra

    Trim : sri auto

    Engine : 1.9 cdti 150

    Year : 2008

    Mileage : 119k

    Default DPF and tuning box and EGR blanking

    Okay, been reading through the forum and it seems there are mixed opinions regarding the following.

    I have a 2008 cdti sri (150) auto, im assuming as its an auto it has a DPF.

    Id like to fit a tuning box (approx 180 bhp) and blank off the EGR valve.

    I do 120-130 miles a day, 99% motorway driving.

    Would I have DPF problems or not by doing these mods?

    Opinions please.

    Spent a few hours reading and still not found a definitive answer on whether it should or shouldnt be done. And if not, why not?

    if you blank off the egr you will need a remaper to turn off the light in the ecu so might as well have them remap the ecu instead of a box while there i believe renmap better anyway

    you will need to remove the insides of the DPF which will mean removing it from the car and knocking 7 shades of s*** out of it

    I think you mean EGR not DPF

    Mine is an automatic Signum (with DPF in any case). I have done an EDS remap 30.000 km ago, including EGR closed. No problems since then.
