    thumping in the airbox is a sign of a dropped valve!

    although it doesnt usually get quieter it would be that same all the time or louder when reved

    Well when I revved it when the noise was there I couldn't here the thumping at all only on idle...? How could you find out a valve has dropped? Would it be expensive to fix ...? Started the engine a few times just can't get the noise to come back.? Weird it was on of them when u hear something unusual and not heard before ... Hope it's not to drastic

    thanks

    Worn camshaft and lifters, take the rocker cover and look at the cam lobes and compare them for wear...

    Would worn camshafts be common on the awx engines?

    Before worrying too much could you possible post a sound of video clip up of the noise? This is what bad cams generally sound like when they are worn: PD TDI with BAD camshaft rapping noise NOT exhaust leak - YouTube
