I think I am homing in on the culprit for my battery drain!
I have a suspicion that it could be the factory fitted onboard anti theft siren... I was wondering has anyone had any problems with Battery Drain and a Factory Fitted Onboard Anti Theft Siren??????
Thanks

Yea sorry mate. I forgot you mentioned that. I am getting lost with all the replies and I am trying to make sense of it all when I have no knowledge about this kinda stuff.
So the alarm horn you mentioned, is that the same as the factory fitted onboard siren?
Sometimes when I turn the engine off and take the key out... I hear a high pitch noise which lasts a few seconds. It's not really loud like I would expect an alarm to be but I can definitely hear it. I also heard it earlier too when pulling out a few fuses and then putting them back in.

Does the siren work? Can cause issues when they go faulty. Mine is f*cked, and I get a drain on the tiny battery I use. Had a replacement siren to fit for well over 8 months, just an arse to fit.

8 t25 torx screws to remove
1 x drill bit
1 x cordless drill
1 x dose of hand-fistedness
And you're all good to go!
Surprised you've still got your arch liners on Alex, saving weight and all. They can hoard a lot of crap in them!

I'm not too sure to be honest mate. If I try to set the alarm off on purpose the indicators flash but there is no sound what so ever. Never has been.
But I do know that I hear a faint high pitch sound every now and again sometimes when I stop driving and turn the engine off. Not sure if that is normal or not.
I can also hear a very faint clicking coming from the engine fuse box from the big black fuse in there that says 100 on it. It sounds like a watch ticking but very fast. It does however stop after a while. Again not too sure if this is normal or not.

B6 passats its under the scuttle trim at the back, near the battery.
It lives under the plastic arch liner in the drivers side. It's a stand alone alarm siren for the anti theft system and has a built in battery that draws charge from the main battery. If it's not working then you'll get no audible feedback when you trigger the alarm.

So do these cars have a main alarm siren and an onboard siren? Or is it just the one.
I know they have one of these... http://www.ebay.co.uk/itm/GOLF-MK5-GTI-TDI-TOURAN-JETTA-ALARM-MODULE-1K0-951-605-C-AUDI-A3-8P-/291118033729?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item43c7fcab41
but I didn't know if that was classed as an onboard alarm.
