I opened up my bonnet/hood and saw 3 plastic hatches/covers. small ones under the wiper end of the hood where the windscreen jets are and these are loose and look like they would rattle loudly in sequence with the motor's vibrations. I will tape these up and maybe finally silence the noises for good. Any other ideas about where the noises are coming from??? Doesn't sound anything like the suspension although it is a bit stiff and does make the car go a bit hard over holes and road surface imperfections.
