About 3 weeks ago, the red "alarm" led in the driver's door of my S4 started acting strangely. Upon locking the car it would flash a few times, then go solid red for ~20 seconds, and then start flashing again. I tried locking/unlocking/opening doors, bonnet & boot/switching ignition on & off and nothing changed - the LED stayed solid red after locking, and has done ever since. It has done this a few times before but opening and closing every door before restarting the car usually fixed it. According to Google (and a phone call to Audi Assist) a solid LED means there is a problem with the alarm system, but causes seem to vary - in my old Golf the LED went solid when my alarm siren battery died.
I booked the car into the dealer who have sent me an Audi cam saying the solid red LED is normal "while the alarm system is arming itself" and there is no fault. I find this strange when every other Audi I've driven (including the wife's A3, my old A6 and my loan B9 A4) doesn't behave like this (the LED flashes all the time), and neither did my car in the first ~2 years I've had it!
The dealer have installed an unrelated software update in the car today, so I assume they would have scanned it for faults at the same time, but I can't be sure. So... before I go back to the dealer, does anyone know definitively what a solid red alarm LED means on a B9 A4 - is it a fault? If so, any suggestions on how to get them to take another look - can it be referred to the master tech? Obviously I'm reluctant to let it go if the locking or alarm isn't working properly.
