well im pleased its a common fault and can be repaired and thought the sound was coming from there!
any more info for a novice like me? is it something I can repair or do I need to do the 40 mile round trip to my dealer?
many thanks for the piece of mind

To rempove the siren it is held on with some security torx bolts. When you replace the siren you may need to get it coded with a Star.
