Does our Audi need a timing belt change?

i just had a listen to your engine noise and if i were you i would hve a look at the engine drive belts(fan belts) it sounds as though a belt is rubbing against something plastic eg.cold air intake, fan shroud ,engine covers.check belt tensions and if possible look for wear marks on belts and surrounding parts,it maybe that your timing belt has been changed and the cam belt covers have not been refitted correctlyand the belt is rubbing inside the covers.i recommend you find the cause of this noise before driving your car as it may result in an expensive repair,if it is your timing belt rubbing and it fails while driving it may cause the valves to hit the top of the pistons causeing a hugh amount of damageand several thousands in repairs.if you tackle this job your self get a workshop manuel from a parts retail outlet to ist you as timing is very important and you must get it correct.i think your noise while turning the steering will be the suspension bushes groaning as they get loaded while turning without movingputs more load on them. i dont think this is a problem as most cars do it,if the bushes have been upgrded to nylothane bushes the noise will be louder but perfomance will be improved good luck
