Hi,
There is as you say some confusion ref 2004 models and a CDL. The truth is, that from late 2003 Land Rover re-introduced the CDL as a customer option, it did not do as they did in the early days and fit ALL the transfer boxes with a CDL in the case and then just "hook it up" in the cabin for those customers that paid for it.
The real confusing issue is the Label on the centre console. They never produced "different" labels for vehicles with or without a CDL, so lots of owners see the label and think they have one. If there is no "diff lock" embosed on the knob, then there is no difflock in the case unfortunatley.
Offcourse lying underneath and "feeling" for the CDL nipple is the only 100% way to tell, but the Diff lock nob on the lever is really a good enough indication.
