Is difflock purely mechanical?
Question on my new to me 2015 Defender.
Last week it started with the difflock warning light on.
I assumed difflock was electronically controlled, so was reset on an engine start.

Question then whether it's possible to engage difflock with the ignition off?

Thanks.

Mechanical only, controlled by the 2nd lever.

Maybe you/passenger pushed the lever by accident? Happend to me on a few occasions.

Diff lock is mechanical. Will stay in until you know it out with the lever. It will start with diff lock light on.

And yes you can engage it with ignition off. Kids in front centre seats always used to get mine

Hi Moles,
It is mechanical so can be selected with the ignition off.

The lever is not directly connected to the lock. In simple terms the lever is mechanically linked to the engagement system inside the transfer case. The warning light indicates when the lock is physically engaged/disengaged, not the position of the lever.

The warning light might not come on immediately after engaging the difflock lever as the locking mechanism often needs some rotational speed difference between the front and rear output shafts to engage.

When you disengage the difflock, if you are on hard ground there is a high chance the warning light won't go out straight away. This is because the transmission can "wind up" and put load on the difflock mechanism. The diff lock won't pop out until there is no load between the front and rear outputs. Sometimes you may need to reverse on full lock to help the difflock to disengage. I find it best to disengage the difflock as soon as it isn't needed whilst still off road as a bit of wheel slip helps unload the centre diff and it will then disengage.

Did you purchase your Defender privately, independently or through a Land Rover Main Dealer? If it came through a Main Dealer, I think you should have been offered a complimentary half day out at a Land Rover Experience site. They explain the workings of your Defender. The half day out I took was really valuable and great fun. The sounds made by the Puma's traction control system working is something best witnessed at a demonstration and probably saved me a wasted trip back to the garage. Even if your Defender didn't come through a Main Dealer, the half day experience is well worth paying for.

I've a small collection of Series2 & 3's, so totally familiar with the principle and know how the gearbox works - rebuilt a few in fact. Other than a Freelander 2 a few years ago, this is my first modern Land Rover. Just wanted to know whether the Defender was mechanical, or electronic, that's all. That's not in the manual.....
Interestingly the Defender high range is backwards, whereas the older Series high range is forward.

The vehicle was via an independent dealer.
