Have I got Diff Lock. Panic Panic

Hi Everyone. I am appealling to you in a panic. I have a disco 300tdi auto and I am getting togather with a friend at the weekend to free off my diff lock as I can't get it. I have just read a different thread elsewhere and someone said that some discos came without diff lock as an option!! This would be awful. Does anyone know whether this is true before I waste everybodies time trying to fix this.

Thank you Petr, you have put my mind at rest. Without this it would have defeated the reason for getting the disco in the first place. I will update as to wether I get it freed off.

OMG. Just had another reply saying that I might not have diff lock option if I bought a SII Disco. Call me thick but I don't know what that means. Mine is a 300 tdi auto, 1996 Blue. Does that help??

Hi. If your Disco is a '300 series' then you certainly will have a diff lock. These were removed (as an option) on the introduction of the Series II Disco in late 1998 although on the early models the spigot was still fitted to the transfer box so, technically, diff lock was still available. Last model year of the Series II saw a re-introduction across the model range .

Yours is probably just stuck, as you say. Lack of use can cause this to happen

Thank you everyone for your advice. I am sure mine is a 300 and so I will persevere to free off the diff lock. I would hate to still get stuck in the mud needlessly.

You can still get stuck in the mud. The diff lock will help but it's not the panacea you may be hoping for. It only works between the axles and not across them. Axle diff locks are available but cost lots of money.

I also have a 300 tdi
Is a light supposed to come on in the light console when i engage low ratio?

Not when you engage low ratio. The console light is just for when diff lock is engaged.
