The part number for the upgraded alarm is: 8L0 951 605 A. I've just bought a new one off ebay for £44 so keep your eyes out for one on there. By the way, I bought a mkIV Golf alarm from the scrappies for £10, it fits the connection but didn't work, I took it apart to compare the guts to the original one and found them to be quite different.
your the person that prob ended the bidding on the one that was for sale ...
That's me Sick to death of scratching around for one so made the guy an offer ..sorry to anyone else thinking of bidding.
Thats the whole point of ebay oh well .
its a **** siren anyway .
ha ha..alright sour grapes chill out. I don't know why people are so hung up on the volume anyway, when was the last time you saw someone bat an eyelid to a car alarm - whatever sound it was making?
