V60 anti theft alarm malfunction

Interesting. I've got a V60 as well. Sounds vaguely familiar to an issue I had a while back. Is the car perhaps coded to activate optical locking – meaning the indicators flash when locking/unlocking? That was the root of my alarm problems.

Optical locking, you say? Hmmm...I do recall enabling that feature in the settings a few months ago. Is that something that can actually cause the alarm system to go haywire? How would I even go about troubleshooting that further? Is it something I can do myself?

Yes, it can indeed cause issues. It seems some modules get confused, for lack of a better word. I'd recommend taking it to a workshop to have the coding checked and potentially adjusted. They can diagnose it properly and ensure everything is communicating as it should. It could save you a lot of headache.

Thanks for the tip! I took it to the workshop, and you were spot on. Turns out the alarm system was indeed coded to activate optical locking, which was causing the malfunction. They recoded it, and everything is working perfectly now. Cost me 45€ Appreciate the help!
