DS5 Alarm

Post by Maci3k »

Good afternoon forum,

I'm just looking into a possible issue with the alarm on my 2017 DS5

The interior alarm works ok EG if I leave my window open and put my arm in or leave my dog in there. However the manual says that it should also sound if the someone attempts to open the door, boot or bonnet. This doesn't work for me. The Citroen garage said the manual is wrong and no exterior alarm exists.

Can anyone with a 2017 DS5 or similar confirm if this is the case or not?

Cheers

The alarms generally have perimetric and volumetric features:

Volumetric for the interior - detection of air movement in the cabin - which you have.
Perimetric for the exterior of the vehicle. This triggers if the doors, bonnet or boot / tailgate are forced open when the alarm is armed (by default on locking with the fob).

So I don't know what your garage is on about. But of course, the alarm won't go off if the vehicle is locked! I don't see how you can test this without forcing a door open when it is locked.....

How are you testing this? You would need to lock the car with the remote, wait a few minutes then use the keyblade in the lock to open the door. As for the bonnet, try flicking the catch over with a screwdriver, arm the alarm with the remote wait a few minutes & then manually open the bonnet catch by pulling the cable on the catch.

Thanks Marc/wheeler,

I think I was getting confused with the wording

My manual/handbook says
"Exterior perimeter
The system checks for opening of the vehicle. The alarm is triggered if anyone tries to open a door, the boot or the bonnet.."

It doesn't say anything about being forced. I just assumed it meant trying to open it, when locked, without the key being present (eg someone walking by and trying to open the door by the handle whilst its in a car park or something)

So the alarm won't go off if someone just lifts the door handle for example. They would need to force the door open for the door sensor to trigger an intrusion whilst locked for the alarm to go off in normal operation.

On both our 308 and X7 the alarm goes off if the car is locked using the remote control and unlocked using a key in a door lock. Simply opening the door then triggers the alarm and I have to make a dive with the keys for the ignition to cancel the alarm. No forcing necessary!

On my DS5 I have the volumetric sensors on the A-pillars on each side of the windscreen, they look like little microphones.

I don't know whether it relies on these or have additional door sensors but I can confirm that, as suggested above, if I use the mechanical key to open a front door after locking then the alarm goes off immediately. If you had a flat key fob battery then you should be able to silence it by starting the engine using the key. The key is electronically read by the ignition barrel, this does not require a battery in the key to work. The battery is only for remote locking/unlocking. The doors do not have electronic sensors as the ignition barrel does.

You should be able to test the volumetric sensors by locking yourself in then waving at the sensors.

The actual door and tailgate locks provide the intrusion detection of the access points and the bonnet opening (Perimetric), and the 2 ultrasonic interior sensors located in the A pillars or roof console provide the interior (Volumetric) protection by detecting air displacement. There is also an anti-tilt sensor which is contained within the alarm siren itself, which monitors the horizontal planes of the vehicle by comparing reference positions.
