    overboost is usually sticky vanes in the turbo - needs a good clean and probably ultimately a replacement turbo.

    Boost seems all over the place there mate, under & over in the split seconds its logging, I would check all components along the way from airbox through to intake manifold, which of course includes the turbo, which is 1 of the most well known culprits, but need to work along & see which one makes any difference, noticed you had egr fault aswell, have you checked vacuum pipes & egr movement/components which are also at the back of the engine right side which has cooler & actuator iirc.

    Thats what i thought.. Yeah the only error i have is egr insufficient flow and turbo overboost condition
    Could it be a bad remap.. the people that did it were www.mobileecuremapping.co.uk
    What items can i check before i get the turbo refurbed? i can only see vacuum pipe to the egr
