I bought an X reg 1.4 16v Elegance Fabia almost two months ago and since i've had it the alarm keeps going off so it has been back twice already to the garage which is a Ford dealership and they then send it over to Skoda which is their sister garage a couple of miles away. First they said that they had reset the alarm but that just led to it having a big fit the night we got it back, it went off even when i had the doors unlocked and everything, thankfully it did eventually shut up. They then had the car for about a week and said they had replaced a unit by the interior light (made a mess actually sorts of sticks out) and now it is doing the exact same thing it was doing at the start. It is usually in the evening, sometimes 20 seconds after it has been set and sometimes hours after. Somedays it will go off three times and other days it won't go off at all. I want to take this back to the garage but i kind of want to know what the problem could be first so that the muppets can't miss it this time. I was thinking it might be a dodgy sensor in the doors, i have read that on some Golf MK IV the drivers have had to make sure no air circulates around the car becuase of some dodgy pillar-mounted sensors. It is really perplexing me at the moment and any advice would be greatly appreciated.

Really need a fault code or a diagnostic read out to know what has set the alarm off. It does record what has set it off so we know what area to look at.

Interior monitoring is quite often the culprit (the unit behind the interior light) but so are bonnet switches and boot lights. Also other electrical drains and accessories can set off an alarm.

I have a W reg 1.4 16v....it's also had alarm problems. The faulty interior motion sensor was to blame, and replacing it cured it for the best part. However, it still does very rarely go off....the alarm sounds, but the hazards fail to flash. It seems to be temperature related. The dealer told me that they have turned down the sensitivity as far as it will go (I assume this is true), which again actually seemed to help. It's not a big problem at the moment.

Have noted other 1.4 16v in my work carpark doing the same thing. I put it down to dodgy electrics in the earlier models.
