S Type..XS 2006 Just had the same secondary alarm bleeping problem...had to get up twice in the night and realised the only way to guarantee it stopping was to leave car open. Read the forum and thought it seems like a bit of a faff......so rang my local Jag specialist and took it straight in for investigation. He took the drivers side plastic inner wheel arch cover off, disconnected the delphi unit...replaced cover...10mins work and charged me £10 What was I worrying about?????
