    Evening all

    After several days without a problem on my S320 I now have a strange alarm fault, going off with no prompting every 20 mins - 30 mins, locking and unlocking won;t stop alarm only putting key in ignition.

    I am assuming the siren has gone down and will need to be replaced, is there anything else it could be?

    Too late to disconnect alarm now - have pulled fuses 51 and 77 under rear seat, assume this will disable any further incidents.

    Any help appreciated.

    Thank you, I thought as much but nice to have confirmed.:)

    I assume pulling those fuses will at least let me sleep tonight!

    For info and anyone else in the same position removing fuses does not stop the alarm going off!

    I have now disconnected from Siren and hope for more luck.
