Weird alarm problem...

I HATE dealers, and I don't yet trust anybody in town with my:
- mint cond. loaded 99 VW MK3 GTI VR6
- 60000mi, no mods whatsoever!

I'm having an intermittent problem with my FACTORY alarm
where randomly (at least 1 time in 5) when I arm/lock the car,
the alarm goes off (honks) right away, like something
violated one of the car's alarm rules.
Correct me if I'm wrong, if something is in violation of the
alarm, shouldn't the car NOT let me arm/lock it?????
(ie: you can't lock/arm the car if a door, trunk or hood are open)

Any ideas? I've taken the module out looking for cold solder
joints etc, nothing obvious...

FYI...
info i took from her helped me immensely,
so I will give back to the comminuty!!! : )
THANKS!

It turns out that BOTH my posted problems:
"Weird alarm problem..."
and "Turn signal problems... Please Help"
are both related, despite the alarm misbehaved for
weeks before the turn signal problem showed up...

THE PROBLEM WAS...
As Boschman pointed out in another post that
the Rear (left) tail-lights 8 Pin connector had a
corroded ground connection.

I was mainly intending to fix the turn signal problem,
and I cleaned and tinned the terminals, and the turn
signal problem went away. BUT in fixing that the alarm
now behaves properly.

SO. (and if you read my "Weird alarm problem..." post)
what I'm deducing is that, every time I armed/locked the
car, the module would flash the hazard lights, including
the (tail-light) like normal. And since the ground connection
was flaky at the tail-light, the bulb was trying to steal a lower
voltage potential (ground) from the alarm module, thereby
setting the alarm off, because of the weird sudden voltage
drop to the module.

I can't confirm my theory, but the alarm hasn't misbehaved in
a while. (...knock on wood!)
If I discover otherwise I'll update this, as I solve it!

Sounds possible, I'll have to remember that one.
