Hi Neill,Hi Rich,
Unfortunately not all transfer boxes had the CDL fitted. Mine only has the sticker showing difflock in the cabin, LOL.
You might find the answer with a search. As this has been discussed before. The box actually has a serial number that should identify if one is fitted.
However , going and posting on the Disco forum is also a good plan.
Cheers
Well it could give you a big boost in your off road abilities... which is why I am trying to find out if it will work on a 2003 face lifted D2Oh,
I must be mistaken and my Transfer box must have diff lock inside it then.
Cheers
