Another trip to the dealer...

Yet another trip to the dealer....this time for a knocking sound from the front somewhere, noticed mostly when entering my street because there is a short cobble stoned stretch and you can hear something knocking about a fair bit, it sounds low down around the wheels but it is hard to tell for sure. Think occasionally I can feel it through the steering wheel also but possibly imagining that, any ideas what it is likely to be? Got booked into Renault this coming Wednesday, 1 months warranty left but I will be extending that!
 
maybe the sameone, i was told it was called a lower arm link, sounded like a very loose knock, as in every sudden mountment ie changing gears, breaking and going over speed bumps it would knock
 
Yeah that's what I was thinking myself I had the same thing on my old s2000 and it was a front drop link, hopefully get it sorted out, it is pretty irritating...car only has 19k on it, bit disappointing.
