I have a 9.3 aero manual sedan (2006 Australia). Almost since new there
has been this faint tinkling noise that come from behind the front seats
somewhere. It mainly happens when the car suddenly accelerates or
brakes, so it seems to be caused by sudden movement. Quite faint and
best described as sounding like champagne glasses being "toasted" with a
single "tink". It seems to be getting more frequent and the car's being
serviced this week.....hoping someone might be aware of what it is so I
can let the service people know because history has taught me they
aren't real good at working these sort of things out.
