Alarm behaviour

Out of curiosity, does it go off regardless of how you have driven that day, as in has the battery been worked hard and not had a chance to recover?

IF, I was to try to find a link to the amount of driving, then I might be inclined to argue it's after a period of inactivity.
So I hadn't used the car after it came back from the dealers on Friday.
And last week when it went off, I was ill all the previous weekend, so again hadn't used it.

It was only a thought and difficult to speculate without seeing the stats for a broad range of this fault.

The one and only (fingers crossed) time my alarm went off, was on the day I did a stupidly short run. Normally, my driving is at least 30 minutes and involves fast roads as well as city stop/start driving.

well, it is interesting, as I have had the flat battery issue too, and I'm not a fan of coincidences.
They reset the battery monitor, charged the battery and told me it was fixed, I had a period of 3 or 4 months with no issues and then this started, so I think it must be linked.
Maybe the alarm battery has it's own battery charge monitor which is always overlooked?

just to add though, in 'regular' use, it's a 80 mile round commute into London everyday.

Assuming that you get a good run, an 80 mile trip should be more than enough to keep your battery healthy.

Sorry if you have already stated this, but does the alarm go off at the same time?

ish...
On the occasions I have heard it, we've had 3 or 4 times at 4.30am, one at about 8.30am, one at 9am (this morning). And my neighbour reported a 1pm alarm call to me too Neutral

My alarm went off last night.Looked in the cars computer alarm setting an it said that the alarm was triggered by volumetric sensor.Does anyone know how a volumetric sensor is triggered ?

RacingSnake · 10-02-2013 03:55pm

^^ it's the interior sensors.

Movement normally, was it windy/raining? Volumetric sensors can be Infra-red or microwave and detect changes in the transmitted field.
