V40 Anti theft alarm malfunction
Summary of the thread
A 2004 Volvo V40 is experiencing an anti-theft alarm malfunction, where the system indicates it should activate the indicators, but the alarm itself is inactive. The issue is identified as a coding problem. A workshop visit confirmed the diagnosis, and recalibration resolved the malfunction.

No random alarms, it's completely inactive. The error code points to a constant malfunction, not false alarms. Did yours also have zero alarm function?

Ah, mine was different then. My alarm was randomly going off, even in broad daylight. A trip to the workshop might be your best bet. Good luck!

Took it to a workshop. They confirmed the coding issue and recalibrated it. Cost 45€.

I had something similar with my V40. Does the alarm go off randomly, like a false alarm?
