2003 Mazda 6 diesel . took it in for a routine oil and filter change [in Spain] and afterwards I head a sort of metal banging noise in the area of the right wheel well. I thought it might be that they did not put in enough oil or forgot to tighten something but it has been 2 weeks and they can find nothing. I was too that they have check ed everything other than opening the engine. Any ideas... I only need this car 8 more months and then I return to the States. I know very little about cars but this seems really strange.


Thanks
