My 330 Ci (E46) has developed this annoying rattle from the underside of the car more to the R/N/S. Had quick look whilst on a ramp and could seeing nothing obvious. So far I've:-
1)Checked wheel nuts
2)Rear Suspension strut removed and appears in order, even swapped it with the offside.
3)Rear Springs seem okay
4)Exhaust is secure
Sounds almost metallic can find nothing lose. Any ideas please?
