    Default hi speed boost problem

    bit of a strange one this so would apretiate any help

    car is a 2.2 dti sri 2002 plate

    cars fine at low speed whilst boosting around the streets but when i get on to the motorway high speed+try to put my foot down the spanner light comes on+it goes in to limb mode.
    it seems to be if you hold the revs then try to use the boost to pull off/overtake.
    im new to this car so im not properly up on them.i have done some research on here+found split pipes are a common fault so found a split in a boost pipe going to the vacuume actuator+replaced the said pipe but it is no beter??
    HELP!!!

    Had something similar on our 2.2DTi Auto. It had a split hose going from intercooler to turbo. It was a 3cm crack!

    Hmm...could it be that in higher gears (on motorway) it is on higher revs for longer? Maybe something's wrong with the vacum sistem?
    The 2.2DTi we have did go into limp on high speed runs but not in town. A tiny vacum hose was damaged or something. A couple of days before the repair it was doing it all the time and everywhere, low or high up the rev range....
