Hi all i have just brought a discovery 300tdi 2in lift and the 4x4 light wont go out what ever you do with the diff lock i can get high and low range and it drives ok .Now this maybe me as this is nt first discovery and i dont realy know how i should go about getting light off all i could go on it the pic in the dicovery whitch is not very clear any info would be great thanks anthony

 A possible easy fix, Try reversing up a few yards or so?  if not possible switch problem?   And welcome  to the muddy side  :lol:

As above, take it out of diff lock and then reverse it until the difflock light goes out.  Don't drive it on hard surfaces eg tar roads until the difflock light is out because you will be winding the transmission up.

It could also just be a sticky switch.

To find the switch follow the front prop back towards the gearbox. Put you hand up over the top and along the top of the gearbox (well transfer box actually :) ) and you will find a switch that has a two wires plug on it. I forget the spanner size up it can be removed once you have unplugged the wires. IIRC it is just a little plunger type affair and you will soon see if it free to move or not.

I have changed one with the box in situ so not hard, you just can't see it so you will have to do it by feel; be careful not to cross thread it.

....and of course...welcome   :D

hi the light stays on all the time high/low neutral  and discovery wont move with diff lock in neutral  Am i missing something how dose the diff lock work mine just seems to move backwards and forwards and side to side in neutral like i said i am new to this

The leaver controls 2 seperate functions.

Forwards and backwards selects High, Neutral and Low range gears in the transphere box. Neutral gear in the transphere box being just like neutral in the main gearbox.

Moving it side to side engadges and disengages the lock on the central differential, so the diff lock its self has no 'neutral' position.

Its probably worth checking the difflock has diengadged and is not stuck on, the leaver is linked via a spring so just because the leaver is in the disengaged position doesn't necisserily mean the lock is disengaged.
With the leaver moved over to the right hand side (disengaged), the handbrake on and either gearbox or thransphere box in neutral, jack up one front wheel and try turning it. It should turn freely, then move the leaver to the left hand side and try again, it should now be lock and only turn a few degrees at most due to play in the transmission. If it doesn this then its just the light circuit thats at fault.

well clbarclay you are a star  :dance:  moved the lever side to side and light went out thanks

Sometimes it can be a bit reluctant to come out of diff lock if you've been on firm (ish) surfaces. What I have found to work on occasion is to push the clutch down, then coast a short distance. This seems to shake the drivetrain a bit and makes it unlock.

Reversing is my second option if that doesn't work, as it's a bit hard when you're in the middle of a convoy!  :lol:

Glad you managed to get it sorted. I know when I first took mine out of diff lock and the light stayed on I got a little worried and thought I'd broken it...!!! You just get used to it after a while.

Welcome to the fun anyway.
