    Whats that Noise??

    When I start my car up in the Morning you usually get that Motorised noise for about 15 seconds, It sounds like a Hoover, What is it and since driving through a Deepish puddle (on the M5 which I got caught in for 13hrs) everytime I start her up after its been sitting all night and day I get that Hoover Noise but it sounds rough, Like its dry rotating Grinding noise, Any help Folks will be appreciated...

    It's your secondary air pump, that makes all those weird humming noises. I don't know what could be causing the excessive noise though.
