Odd but simple favor needed from another DB9 Owner

[a98pmalcolm]

Hey all. I need an odd favor if someone or a few of you can try this for me, this may sound odd but bear with me
I'm an still chasing down this battery drain and have come across something suspicious.

Last night up on return after a drive I though it would be a good idea to lock myself in the car to see if all the button lights turn off.

The whole time I sat in the car I keep hearing a very quiet chirp every 10 seconds coming from behind the radio unit, almost like the sound of a CD being read. Even though there is no CD's in the disk changer.

Also after the hard lock the head light switch, trunk release and door lock release buttons dim out and the pats light stops flashing.
However the the power window switches illuminate and stay on.

I was wondering if anyone else with a DB9 could test if their car if you have a spare 5 mins in the evening to see if the same things happen after locking yourself in and if this is all normal.

Many thanks
Paul

I would be interested to know what the chirp sound is too. My old DB9 did it and I always wondered what it was. The DB11 also does it so I presume it is normal rather than a fault - perhaps the air con unit ?

Chirping could be high frequency chirps from the interior alarm sensor.

Hi.

Just checked. Mine does exactly the same.

Is in the garage so I looked in few minutes after locking and the electric window switches eventually go out.

Many thanks for the reply's.

Really appreciate it

Decided to time everything and the window switches do turn off eventually.

After locking the doors:
20 secs - Hardlock
55 secs - buttons dim, window switches illuminate
3.30 mins - bluetooth power down bleep
4 mins - Garmin sat nav upgrade powers off
6.30 mins - window switches turn off
