I've read some did have it, but not the option for the handle to engage it. Why or when that would be? No idea, and I have not witnessed that firsthand, but that is what i have heard.

 

Gotcha.

Its a mystery!

 

I very much doubt that any '03s transfer cases will have the CDL mechanism. Those seem to have run out sometime around late 2000/early 2001 so it would be a stretch that any would have been installed a couple of years later unless Rover had already started assembly of the 2004 drivetrains but was still putting the 2003 interiors on them. It's worth checking but I wouldn't hold my breath.

 

The mystery will continue.....

 

I knew the 03 had no CDL but I was looking for the best condition Disco for the $ under 5k and it happen to be this 03. I no longer do serious offroading like I use to so CDL isnt a big deal for me. Its still a great off road
vehicle even without CDL. Traction control ,hand break and good off road driving skills . Good to know it can be added though,
