The alarm on my 2007 Volvo V70 (S80 platform - not latest shape) keeps
going off for no apparent reason. I can stop it happening by pressing
the button to disable the spacial detector before locking the car, but
that reduces the security level, so I'd rather not have to do that.

Has anyone got any experience of this sort of thing, and any bright
ideas of what to look for? I've come across this sort of thing in the
past when windows have been left slightly open on hot days, but all my
windows and doors are firmly shut!

I guess that an OBD-II reader might throw up some codes which would
offer a clue - I'll post separately on that!

Don't think OBD-II covers alarms.

If it's not something blindingly daft like a wasp or fly caught in the
car, then it might be an ultrasonic sensor going south.

Unlikely. OBD just does the basics of engine management. A Volvo-specific
diagnostic may well, though.

Had this with a 2004 V70.

What seemed to work - but eventually didn't - was taking change out of
the well pocket between the seats. There was a comment somewhere
referring to a sensor located there which became upset at having metal
nearby.

But it may be worth a punt.

There is a known problem with the alarms of Volvos. The battery dies.
[It has to be battery powered for security].

To add to your woes - replacement units are expensive [~£150*] and they
are not easy to replace [obviously you would prefer if if a thief could
not just unscrew it].

I'm not aware of any live creature moving about in the car, but I'll
re-check. It's been doing it for far longer than the life expectancy of
your average fly. Maybe spiders live a bit longer?

You may be right. My Haynes manual suggests that a Volvo dealer would be
able to use some sort of diagnostic device - but doesn't explicitly
mention OBD-II in this regard.

If you haven't got a reader, a OBD-II adapter/bluetooth transmitter
(ELM327) from Ebay for less than £10 coupled with the Torque App
(Android and Apple) for a smart phone works very well.

I suspect that an alarm sensor may not show up on a OBD-II fault report.

I had a similar problem with an S60 and found that there was a touch of
dampness in a sensor at the lower part of the engine, once the dealer
replaced that all was well.
Also had a problem with a Volvo v50 where the problem was with the wiring to
the caravan.

My 2003 Zafira has the same problem. I was advised that it was due to the
rechargeable battery within the sealed sounder unit not having enough
charge in it - the unit interprets this as someone tampering and trying to
disconnect the alarm, so it goes ape-**** as a result. I had the sounder
replaced (not possible to simply change the batteries) - it was a very
expensive component and quite awkward to do as it's concealed somewhere up
in the wheel arch - and that sorted the problem for quite a few months,
however it came back.

I suspect therefore the unit's not getting enough juice off the car or
something; however I've not investigated further and these days, I'm afraid
I just disable it on the basis that's a pretty unattractive vehicle for
tea-leaves, and there's never anything of value left inside... touch wood.

Just seen on TV that a rat was living in a car. Lots of trouble that comes
with it. Lights fall out, Alarm goes off.
Idea??

I think if there were a rat in the car, I'd have seen some evidence by now!

I have a Oct 2013 V70 and the alarm goes off with no good cause every 5-10 days. The interior sensor has been replaced and it then it went off the very next day. Volvo dont seem to know what to do.

Does the alarm have a way of overriding the internal volumetric
ultrasonic sensors when armed? If so, see if that prevents the problem.
It'll isolate it to whether it's the ultrasonics or something else.

Other than that, it's a warranty problem. Keep leaning on them. If they
continue to be useless, try another dealer or escalate it to Volvo UK.

Bear in mind, though, that if it IS the ultrasonics, it MIGHT be
something as simple as a spider in the car...

May be as simple as alarming it with the driver's door open.

Or leaving it with a window slightly open.

Hello
I have the same problem a year ago. I fix the wires to the lid in the back, as it was broken. But now the alarm has gone off several times again. Always with phones and/or Ipad in the car. So I suspect Bluetooth, wifi or mobile-connection to be the problem.
There is no messages about why the alarm has gone off. With the wires I think there was a specific message.
The dealership said last time I asked, that they did not now off any problem.
But it Is a problem to test, because off the Sound/noise...
So I look forward to find out. I must find a place, where it doesn't matter with the noise. I have a volvo v70 II, MY 2007.
I now this is an old tread, but have someone found the error.

I found this on a house alarm once and basically mobile phones and
lightening tended to set it off. Small value capacitors on all the wired
inputs to the alarm more or less cured it, but it still did have spurious
alarms which could not be traced to anything.
It might be worth a try in a car, as its bound to pick up signals on
unscreened wiring, and if that is seen as somebody tampering then the alarm
sounds. I believe the house alarm used something called a window comparator,
so an open or short circuit set it off or in fact any liquid that partly
shorted the wires. It was supposed to be anti tamper as it used a balance
system to match the stable resistors in the sensors with one inside the
alarm, if it went out of balance it set the aarm off.
Don't know if car alarms work the same way.
