Hi, just acquired a fully restored p6 3500 and I'm getting a tinny/metallic knocking noise when I go over bumps,large or small, in the road. Tried bouncing up and down on the suspension and not a murmur however as soon as on the road its back again. Had it on a ramp and neither the mechanic or I could get to the bottom of it. The suspension, steering etc are all new. sounded like it was something to do with the metal wheel disc but checked that and nothing.
any ideas greatfully received.
