Hi folks, I'm still without a functioning alarm, as I really can't get my head around what's wrong (and I'm still without documents to get the car taxed and down to Audi)... There's a lengthy post on what exactly I've found out about the alarm (read: how it's broken) HERE - but to save you all that reading I can sum it up simply... Somehow in the process of replacing the audio rig in the car, I've upset the alarm, in so much as now it seems it's just not arming at all. No indicators winking to say it's armed, no LEDs flashing in the doors to say the same /ubbthreads/images/graemlins/frown.gif - I've tried some of the daft combinations of locking and unlocking with keys and remotes and using the interior monitor disable button on the pillar, all with no effect. I'm just wondering if you guys know whether the part shown in the jpeg does only what its name suggests (interior monitor control unit), and merely looks after the sensing components for the cabin, or if it plays a more integral role in the arming of the alarm (- is this the main component of the alarm system or just a "closed-circuit" for the monitors at the top of the pillars?) Also, do any of you know what one of these little fellas looks like in person? The illustration isn't too enlightening... I guess that it's going to be on the right (rhd car), contrary to the image, because the interior monitor disable button is over there too. Unfortunately I've rebuilt the interior now, which makes poking around by the wheel arches pretty tricky, but I can't help wondering if it's something I've seen at the upper-front corner of the arch (peering through the access panel in the right-hand boot-trim). As always, I owe you all a debt of gratitude for just reading one of my waffles, and even more so for any info you can fire my way. /ubbthreads/images/graemlins/beerchug.gif Cheeres, Rob.
