    I have a 55 plate a4 avant, YES just found out its a BLB :eek:(

    The car has run perfect up to 120000 miles yet on starting from cold I have noticed a sound that sounds like a stone being thrown around under the bonnet.

    On inspection and trying to locate this noise I cannot tell if its coming from the alternator or somewhere around that area???!!!

    The noise dissapears after a few revs.

    ANY HELP OR ADVICE MUCH APPRECIATED.

    Chris

    PS - if it was O/pump crank in sump etc, what sort of noice would that give??
