    Default Loss of Power - 70mph + on motorway. – 19-08-2009,07:48 AM
    I think I am starting to narrow down my fault a little bit.

    this happens most mornings as i get on the motorway and reach 70mph. The power at the bottom of the accelerator drops. There is still power if the accelerator is depressed slightly. This almost feels like the turbo has been switched off.

    I have tried replacing the full MAF unit, didn't work.

    Can anyone help out further ?

    Is this sympton common with the turbo possibly needing cleaning out, would this cause it to stop working at 70 ?

    How does the N75 valve work, could it be this thats causing the turbo to shut off ?

    Please help.
