Dinging sound?
This is driving me nuts! 
You know the dinging / bell sound that occurs when you leave your lights on, or open the door with the keys in etc.. Well my C5 just started making that dinging sound (very very faintly) when driving it. It works at normal volume if I leave the lights on, etc.. But when driving it, I hear the same chime over and over again, just very faint. No codes on DIC, all the doors are shut, etc..
Anyone have any ideas? The car runs and drives fine, just freaking dings all the time..

My 04 doesn't have any sounds associated with the seat belts, does anyone else's? The only warning I have is the light.

Interesting problem. If you find the cause and solution, please post it up.

Turns out my dinger is fine. It only lasts about 5 seconds, so I don't get much use out of it.
Seriously though:
The seat belt ding is a slow ding, the lights on, a little faster, and door open with key in, a different speed from the other two. So, maybe if you time the ding you're hearing you can match it up to which of the three circuits it is associated.

When does it start?
Do you hear it when you first get in the car with your seatbelt fastened, but no key inserted?
Door still open AND closed?
After key is inserted?
After car is started?
After car is in gear?
After you lay down in bed?

I have worked on one similar problem for someone where the door latch switch did not function correctly but that may not be your problem since it dinged normally (loud) for him when the door was closed and should not have. The switch was staying closed when it should have "opened" when the door was shut.
Not at home now with the FSM but we may have to pull fuses for different circuits to see if we can get it to stop and then go from there.
I am pretty sure (my old memory) that the BCM gets all the inputs and if something it not "correct" it sends a serial bus signal to the IPC to actuate the chime speaker. I hope it is not the BCM or IPC acting on it's own for some reason. I have worked on issues where the IPC has a problem and the chime speaker makes noise but never a "real" chime.
