Hi i'm new to this forum, i currently own 59 plate Tdi Octavia VRS, i love the experience i've had with this car until now. The alarm has decided to go off randomly (it seems to like the night time for some reason and i have Parkinsons Disease which means it takes me a while to get the keys, get dressed and walk down the road to where the remote can reset the alarm.(Really helps with relationships with neighbours) until now when the alarm seems to have developed a mind of its own. on Sunday there was like a chirping noise coming from the car alarm which i could have sworn was a bird singing, then the alarm came on properly. i reset it with the remote and thought no more about it. At twelve that night the alarm started once again and would not respond to the remote, only if i held the reset button in on the key. Fearing for my life from an attack from an irate neighbour, i started the car and drove off down the street with the lights flashing and the alarm wailing, after a while it stopped. i rang the breakdown people as i just wanted someone to help me, it was either them or the samaritans!

 

The recovery guy finally arrived, he read the fault codes off the ecu mumbling something about a module, i ended up parking the car outside the garage that i use for repairs. They have already diagnosed the alarm fault to be the alarm siren itself which i had replaced (not cheap) one new battery, ignition barrel, several visits which involved turning down the sensitivity of the internal sensor to 50%. all to no avail. its strange that whenever i have taken my car to this garage for this alarm saga, when they plug the reader in there is never any fault codes i'm reluctant to take it to the local dealer as i haven't got the cash to satisfy the money grabbers. What i need is someone who can recommend a garage in West Norfolk that specialises in VAG preferably Skoda who does a decent job for a decent price cos at this rate i'm going to have to auction one of my kidneys on Ebay. 

 

would appreciate any help

 

 

This could happen if there was some damage to a module as you have been told already, or there could be some water reached contacts maybe for some locking mechanism? You can imagine that there will be no error codes because the car literally thinks that it is being stolen. I can't imagine how to test this, but i am just basing from my experience with the power washer and rear luggage door. It got some water in the switch and was opening on its own all the time, until it dried up.

 

What you can maybe do is try to place the car on more secure area and not lock it at all, so the alarm wouldn't go off at night. Nowadays no one really checks if the car has been locked anymore because of the alarms, but please do this on your own risk.
