URGENT: tailgate problem

The actuator does get tired, like all of the door actuators in the car.

There is a tiny el cheepo electric motor that gets all guncked up around the brushes and causes it to slow down to the point that it stops working.

On my passenger side door actuator I pulled it apart and cleaned the brushes and it hasn't missed a beat in the three years since, there is a post on the disco3 site that showed me this.

The tailgate actuator can't be disassembled so easily, but I believe it can be cleaned if you want to by drilling a hole in the body of the actuator and spraying contact cleaner through it. I did mention it in a thread I started last year and would love for someone to give it a go just to see if it works?

Taking the trim off with lower tailgate open is 100x easier than when it's stuck closed.

I agree with Scott 100%. The cable broke near the actuator in my D3 and I had to break into the lower flap from inside the luggage space. I installed an emergency release using an old bicycle brake cable running to just behind the RH passenger door. I was just thankful the drawers and fridge were not on board, otherwise I'd still be there. So definitely leave yourself the ability to have good access to the inside of the lower panel until you get a proper emergency release installed. This should really be a high priority mod as we seems to hear about it just a little too often - it's on my list for the D4.

Thanks for all your replies, I

I pulled all the trim off while I still had access to the rear, so it was an easy job. I still can't work out why it failed though, as everything looks like it is working, it is just a tiny bit slow. My one thought is that the door open sensor at thee back might have been malfunctionng also...

anyway, I have ordered a new latch and actuator to replace it and be sure, and will put an emergency release on the new one.

It has been a good exercise as I understand how it works now.

Cheers

This theory would be proven if the actuation works ok using the key fob because that's not relying on the microswitch in the tailgate handle to operate the actuator.
And possibly the extra voltage available with engine running may be making a difference if the actuator is tired.

Lucas, you're probably all over it but I wrote up a little thing in this thread for the manual release cable using a bike cable that both James and I have done and are very happy with:

Hi all

Just went through part of this procedure tonight :-) Occasionally had the tailgate click, but not unlatch but after a few tries it opened. Yesterday I was putting on an AULRO sticker on the tailgate and once that was stuck on, the tailgate would not open. Go figure :-)

I had been following and saving the many many threads on here and DISCO3.CO.UK - Index about this problem. Fortunately for me pushing out from the inside while Jill pushed the outside button opened the tailgate. So tonight, whilst we had it open, I removed the internal rear trim to expose the latch and the cable. Took about 1 hour to get all the trim and bits off. Now I can pull the wire cable from the inside when needed.

Next will be to rig up one of the manual pull modifications that have been suggested.

I really do dig that sig that a few members have referred to; "Land Rover; making mechanics out of motorists for nearly seventy years...".

Scott's excellent manual for this mod is here: https://www.aulro.com/afvb/attachmen...al-release.pdf

I made a couple of small mods to the mod listed here: Scott's Discovery 4

One very minor correction too - the pic for the hole position on page 7 should be as per this pic below

You need to get a dry film lube.Sillycum or graphite are the go.They are available in a spray,the graphite spray wont be as suitable as its like a black or grey spraypaint(more used in heavy duty applications).Graphite powder is OK,but may not remain where you need it.The silicone spray is clear.

i wouldn’t use silicone spray either, like all the others, WD40, Inox, RP7 et al, it will also attract dust eventually. Get yourself a can of Teflon spray from one of the Supercheap/Repco stores and use that.

David your link to the additional mods is broken, this should work

Nice work by the way

Hi all

A few posts ago I mentioned that I've got the same problem on my D4 tailgate. Last week took off the trim and am currently opening the tailgate by putting my hand in from the inside and pulling the cable. The wife does not seem to want to do that. Anyways had to wait till I got a T30 Torx screwdriver to remove the cable mechanism fully.

Tonight I pulled out the mechanism. It's working but the actuator assembly lacks enthusiasm. When pushing the open button on the upper tailgate, the cable pulls in about 1/4 inch. It really needs to pull in 1/2 inch to open the latch. Haven't yet checked the voltage or current drawn but prob would not be much use as I have no idea what it should be pulling or what voltage drop it would normally cause. So I think I need to replace the actuator assembly (part # 999840).

Scott's writeup is ace and the addendum to it. Have printed it off to refer to while working on the tailgate.
