Random, feint single "beep" in car, 06 Vantage

[Krhuangbin]

Have heard this 2 or 3 times now in the last few months.... a 1-2 second quiet beep comes from somewhere in the car. It's not the same sounder in the dash or wherever that the parking sensors use, or the start up or warning chimes.

Sounds completely different, quieter and "distant." Occurs when driving.

Weird - any idea what this could be? I thought TPMS but pressures are fine

Internal battery failure on the alarm module…..I am totally guessing..lol…hope you find out…

I was thinking along the same lines, failing battery in the tracker.

Ha thanks - does sound like a standalone warning thing so ill see if I can track down

Don't leave it too long, once the battery dies it can spew its acid and destroy the circuit board meaning a replacement alarm rather than just swapping out the battery, albeit by opening the sealed unit.

These are NiMH batteries. They won't leak acid.

If it is the tracker or alarm batteries failing though, they will draw from the main battery so you'll need to put it on a charger on it, to avoid a flat battery after a couple of days.

In my case, a message came up on the dash intermittantly, saying, ALARM SERVICE REQUIRED. I didn't get any bleeps.

thanks for that.

I reckon it may be alarm battery then, pretty sure tracker is disconnected, as the battery starts the car strongly, even after 4 weeks of no driving (without trickle charging!) and using the no-fire crank method for oil pressure for 5-10 seconds... I understand tracker is the common reason for battery drainage.

I'll check both though
