Ok guys, Ive had 5 Range Rovers now, and like to think I can talk with some authority on the subject. But I find myself looking to buy my first Discovery, probably a 95 - 97 Tdi auto. Now my first question, I was reading through the forums and a question was raised by an owner of a Discovery " How do I lock my diff, there is no switch or marking on the stubby lever" Now the answer came from some wise young person that if there was no position marked on the transfer lever "you havnt got a centre diff". No this doesnt sound right, surely the disco, like the Range Rover Classic from 92 has a viscous centre diff ? am I right ?

Secondly, I want to avoid the EDC system found on the later 300 Tdis when I go looking, what year was this introduced ?

Thanks guys
 
All series one discovery whether manual or auto had a locking center diff but the diff lock became an option on the disco series II, discovery has no viscous coupling like the range rover.

EDC was on auto and some manual Tdi's, there's no year that it came in, just some had it and some didn't.
 
I have the label fitted in my 97 300tdi auto. I can select Diff lock by pushing the lever over to the left either in normal or low ratio which is selected by moving the lever forwards. It advises that the vehicle should be travelling between 0 - 5mph and neutral is selected during the selection.
 
200 & 300 series Disco's have centre locking diffs as standard.

Disco II (i.e. Td5 on) have a centre diff, but no locking facility as standard (they consider the 4-wheel traction control good enough) You can buy kits to lock these diffs, but after 2002 they removed the ability to lock the diff altogether (presumably to save money).

Hope that helps clear things up.

Matt
