It'll probably be easier to disconnect the battery for 20 mins . . .

Re: Alarm failure
Yes it does, with the car locked, how do you get the bonnet release, i'd be impressed to see that, LOL

Re: Alarm failure
I had this problem with my Stilo recently. Turin Motors @ Leeds did a full electrical check and found that the overhead alarm unit was faulty and completely unrepairable. The same on mine, The buttons did not work and the telephone microphone went at the same time!
Check if the Ultrasonics work, if they've failed as well then it's likely a new part. According to Turin this is a common fault on the overhead units that feature the Telephone, Ultrasonics and alarm buttons.
Quote from Fiat for a new part?
£175 + VAT + Fitting.

Re: Alarm failure
The microphone is completely separate on the header unit so this is very bizarre bubble. Was there a main cause (e.g. water ingress) that caused it?

Re: Stilo alarm
Funny you should mention this, as I'm having identical alarm symptoms. Except, my alarm goes off with no disturbance (parked quietly in the garage) - seems to always go off a few minutes after setting.
I have a theory - dropping battery voltage. If the battery is not in the best health (mine isn't, although obviously the car always starts easily), then perhaps the voltage is pushed up temporarily with the engine running and self-discharges to a lower voltage after I switch the engine off. Maybe the alarm senses a drop in voltage as indicative of tampering. I can't bring myself to replace that genuine Magneti Marelli battery - it looks so much cooler than the ordinary Exide etc. batteries
My roof console is loose (hangs lower on the right side) so I sometimes wonder if that is also a possiblity - do the ultrasonics have to be specially-aligned to bounce around the windows? I keep meaning to get the hot glue out and fix it up there - there's no broken clips or anything but it just doesn't fit right. Probably never did.
Finally if you want to lock the car without setting the alarm, you can always just twist the key in the door. That's what I do when I want to park without the alarm going off five minutes later. However after a few weeks of doing this, I now find that the first twist of the key frequently has no effect (or locks the driver's door without locking the others!) so I do it a second time. I don't know what's happening there but it sure as hell isn't broken wires or 20-year-old flogged out Swiss motors (like it would be in an Uno 70)

Re: Stilo alarm
It's obviously an issue with your ultrasonic sensors. Did you not try the suggestion of closing all your airvents (or putting the ventilation system on internal recirculation before switching off would achieve the same effect)?

Re: Stilo alarm
haven't tried closing all the vents yet, when I'm next at work I'll try putting the air on recycle see if it works if not I'll try closing the vents.
Only other alternative is to insulate the ultrasonic sensors located in the interior light with some foam or tape so they're not as sensitive :chin:

Re: Stilo alarm
Yeah, I heard Dave give that info too, although I don't see how revelant that is - the sensors are properly mounted into their holder, and wrapping them in foam surely would do nothing? Not arguing, just don't see it myself. Making them "less sensitive" is nothing to do with wrapping them in tape, as they act like parking sensors, receiving the difference in phase from the transmitted signal. The face of the sensor, the TX and RX part, will not be affected by tape wrapping.

Re: Stilo alarm
The alarms must be quite sensitive. Mine says break in attempt whenever it is parked in town in the underground car park, it must be the vibration as my motorcycle sets it off as well when i drive past. I would rather have it too sensitive than not set on at all. This is the factory fit one as well.
Still cant get the deadlocks to work though.

Re: Stilo alarm
Right an update now.
With a couple of times of FIAT saying they can't alter the alarm it went in today, they said they have tightened the pins? don't really know what that means, anybody shead some light?
Haven't had time to try it yet but i'll let you know when
Oh and it was done under 3rd year warranty

Re: Stilo alarm
"Tightened the pins" probably refers to the pins on the connector plug; they must believe that it is a loose connection causing this.
Did closing the vents / putting it onto internal recirculation help Dan?

Re: Stilo alarm
closing vents did nothing and putting air on recirculation did nothing.
Been parked in the pub car park today and it's gone off again :bang:

Re: Stilo alarm
Hmm, a Stilo electrical challenge, me likes these.
When you arm the car, does it give it's one elongated beep, then followed by another shorter one or a sequence of beeps? Or is it just the normal one?

Re: Stilo alarm
Lol, I get what you mean. Thats good.
So, this problem - you said before that it goes away when you turn internal ultrasonic sensors off. Was this a fluke or a definite solution?

Re: Stilo alarm
Yep, when I turn the ultrasonic sensors off the alarm doesn't keep going off when a bus/van drives past

Re: Stilo alarm
Ok, I would take off the header console and check all wiring there; especially the little sensor plugs. Dodgy connections is most likely causing this.
Know anyone with a factory alarm that you can swap the header console with?

I'll try that tomorrow morning and let you know, cheers Rich
