    Probably sticking vanes in the turbo causing the problem.
    Would need logged with diagnostics to be 100% but it certain sounds like it needs a new turbo.

    sounds like its going into limp mode, have you had the car scanned for faults yet?

    As Marshy said, sounds like the turbo needs to be replaced.

    ok can the vane in the turbo not just be cleaned is it worth trying something like red x or sommet in it like that just 2 see if that will help as the car is fine up to 80 mph could it just be clogged up

    You can clean the turbo, don't think redex will clean the turbo though.

    Heres the guide:

    It won't go in to overboost in lower gears. Although its 80mph you'll probably be able to replicate the fault in 4th or 5th gears at lower speeds.
    80mph in 6th will be asking for max boost and if the vanes are sticking it can't reduce the boost properly causing your problem.

    There are some treatments available to clean the turbo which are a bit of a gamble whether they work or not.
    If your keeping the car with that mileage I'd be replacing it.

    Mine was exactly the same when I bought it anyway at 110,000 on original turbo and I hered mixed reviews on cleaning the vaines I had it reconditioned and remapped and it has been great since , when the guy doing the work stripped the old turbo the shaft was bent also so was best thing to have done anyway

    3rd gear ,very steep hill give it some beans and it will overboost . dont try to clean the turbo with mr muscle oven cleaner like most muppets do , take it off and strip it down and do the job correctly . will make a hell of a difference to how the car responds.

    £250 to £450, I paid nearer the top price they were recomended and it was extra for a quality billet alloy compressor wheel
