Have had an odd 'knocking' sound coming from the rear driver side wheel arch of the car when breaking / driving slowly / over bumps etc..
It sounds like it's near the petrol tank but i'm not entirely sure..it's not there ALL the time but it's very frustrating and i'm not sure where to start.
Does anyone have any experience of this at all? Considering taking it to a dealer but don't want to get raped with charges if someone can point me in the right direction first

Thanks again!
Cheers
Andy
