    Default Help needed please - 1.9cdti running rough

    Looking for a bit of help guys,

    For the past month or so the car has being running a bit rough- when sat at idle the engine will 'shake' and gets worse if i hold the revs around 1200rpm, anymore than this and it stops. This doesnt happen all the time, but it improves once the engine has warmed up (still shakes slightly). It generally feels a bit sluggish low down, but once it hits the turbo the performance is normal. It also feels 'lumpy' when coasting up to roundabouts etc. like it could stall.

    Bit of background info;
    - 1.9cdti 110,000miles
    - full service in Feb
    - EGR blanked
    - K&N air filter
    - swirl bar loose but attached
    - remapped by MAS
    - mainly used for short journeys. It occasionally runs a bit sluggish because of this, but a blast up the motorway usually sorts it out, not in this case though

    - around 2months ago i accidentaly put two gallons of petrol in the car, brimmed the tank with deisel, driven around 10miles the day after for the tank to be drained. The guy who drained the tank said that he usually advises people to change the fuel filter when this happens, but as i had changed it the week before he said not to bother. Could this be causing problems?

    Any help greatly appreciated guys,
    thanks in advance

    yes i have my own code reader, at the moment the only fault showing is P0400 because the egr is blanked.
    When it was remapped this was disabled but Ben at MAS advised me to plug the egr back in when i got home. did this and the light re-appeared. I've been emailing Ben for weeks to try and resolve this without any success, he doesnt know why it has happened, and i havent had time to go up there for him to check it out via laptop etc.
    could this be hiding another problem?

    that could be something to try, thanks. The egr has been blanked for over a year though, the light has always been on, even after the remap about 4months ago
