    Loss of power

    Ok, bit scary going round M25 this morning to work got to about 4000 revs going up through the gears inot outside lane to overtake suddwnly as if I had turned the engine off then dropped below 4000 pick up again scared the life out of me. Did this several times but now seems ok after car been stood all day. Any ideas?

    Vag-com it.
    Boost cut can be caused by lots of things.

      More than likely it is the Hall Sensor.

        It can be due to lots of other issues as well.
        A slight boost leak can cause a fuel cut, ECU losing power and restarting or an error in processing, etc... many possible causes.
