Alarm going off.

Hi all.
I get the feeling this has been asked before but I can't find the exact answer. The alarm keeps going off. Taken it back to the stealer and they said its the tilt sensor in the boot. £350 for a new one despite being under warranty. It's a 2015 model. They've disconnected it for now, so the car is usable. I'd thought to buy a 2nd hand one, not ideal if they're prone to failure but will get it up and running again. Does anyone know where it is located and also, are they plug and play or do they need programming to the vehicle?
Thanks in advance.

Why is the car unusable.

Mine has been disconnected for over 6 months, doesn't hinder the car at all. My alarm kept going off and after reading the forums I decided to investigate the tilt sensor, I think it is called something else but essentially that is what it is. On my 12/13 plate I'm sure it was under the front passenger seat but can't quite remember,I still have the old one in the garage somewhere. I removed it to stop it disturbing the neighbours with the intent of getting another one, but the car works absolutely fine without it and I don't get any nuisance alarm trips.

I did take the old one apart, its like a dome filled with oil which started to leak and hence the nuisance activation. Hope this helps Richy

Hi, Yes I can confirm that the tilt sensor, on my 2014 car, is located under the passenger seat. Just pull out the storage box and seat fully forward will reveal it. The sensor slides off nice and easy and then remove the connector, a small screwdriver helped to release the connector. As Richy says above, mine was getting to be a pain and I had to press the sensor deactivation button in the roof to stop it going off. Now with the tilt sensor removed I don't have to remember to press the button when I leave the car and the car is useable. I looked into to getting a new one but at £295 I decided against it!

The tilt sensor shows as the fault with the alarm when plugged in but it is in fact the motion sensors by the interior light that cause the alarm issue. Remove the light and pull the plug from the motion sensors, NO MORE ALARM going off mines been fine for 5 years

Alarm going off!

Hi, i'm new to Antara so be gentle! When i lock the car after about 30 secs the Alarm goes off, i click the key again and 30 seconds (ish) it goes off again then a 3rd time it's OK. I looked at trying to locate the issue (sensor) and removed the frosted plastic cover on the interior light panel and didn't see a senor to unplug? Mine is a 2.0 E CDTI 2007Plate. Any tips would be most helpful before my nieghbors kill me!
