    quick update

    went out and unplugged the sensor just before the air box.. im assuming the MAF sensor?

    it ran fine.. albeit you could hear the turbo whistling?????? should this be able to be heard as the car is std

    also the engine management light stayed on as well as the ESP light!???

    how much are new MAF sensors from the dealer?


    thks

    The cost from a dealer is around 75 + VAT; I'm not sure if this is still done as an exchange scheme; whereby you return your dead one in order to get that pricing on the replacement - that was how it worked when I last needed to swap one; but things may have changed since then.

    Regards,

    Rob.
