My C6 sits and has a little chat to itself nowadays. I think it is the alarm siren, but not 100%. This happens whether the car is locked or unlocked.
Captured on this video, uploaded to YouTube.
Any ideas? I presume the alarm is the same as a C5?

Re: C6 alarm chirruping
Sounds like either water in the siren or its connector or the internal battery starting to fail, cant be replaced separately.

Re: C6 alarm chirruping
Thanks. Will maybe hang on and have replaced at the next service as I’m sure it will be buried somewhere difficult!

Re: C6 alarm chirruping
The control module seems to be located somewhere inside the front passenger glovebox and the siren is connected to this.
So not sure which part you are wanting to replace, (4) is the siren, (3) is the siren support bracket which is on the nearside wing at the front corner somewhere. All parts are showing as available except the internal volumetric sensors (2).
6680W7 is the Siren (4) £174.17
6680V1 is the Alarm control unit (1) £200.54

Re: C6 alarm chirruping
Does the siren have an internal backup battery which may have died?

Re: C6 alarm chirruping
Yes, they mostly do to counter anyone cutting the power - and when they do go, you generally find the alarm starting to go off randomly, more and more frequently when the car is locked.
Changing the control unit has cured the problem on my previous vehicles, although I never noticed and 'chirping' just the racket of the alarm going off!
