My alarm siren went out in friggin' flames. It would go off for no reason at all, when tested it would sometimes work, sometimes at lower volumes, finally not at all. I'm curious to see if yours will do the same, hheha
It's possible to do the physical replacement yourself, (I will post vadis screenshots later). But this also needs to be programmed using VIDA communication, VIDA is something that not all indie shops have(expensive). While you're at it though, you might want to try opening the siren up(nothing to lose, right?) to see if you could spot anything that could be fixed within it. These are known to have internal batteries that will go bad/leak, somehow disabling it. You can probably tell I have experience here
I was quoted $178 at Jim Fisher volvo, and $35 for software.
