I traced the lack of speed limit triggered bonging on my '96 325 TDS
to the fact the bonger was missing!
So I pinched the bonger off my broken 325TD (which I know works, cos
it scared the life out of me one night when it was a bit chilly).
All plugged in, but still no bong.
No "memo" hour chime bongs, no limit bongs (limit LED flashes, so the
OBC II is working that far).
Any ideas? Is there a bong fuse or relay somewhere I should check? (I
fear it might involve going under the dash again, where many strange
and wonderful boxes with a hundred wires live!).
