Here we go - finally stopped raining! Apologies but the car is absolutely filthy but here is the video of mine working.

You can see (and hear) both the lower and upper tailgates soft closing.

Thank you for posting, I wonder if anyone else has lower soft close...

You can test it yourself - just manually raise the lower door slowly onto the latch and the soft close should kick in. Current Fleet:-

Indeed, when closing manually, the soft close engages for the lower door too... Now, where to find an adjustment tutorial...
Interesting fact, when cold (it's 3 degrees Celsius), even the upper door slams without soft close!

Another interesting fact - if your upper tailgate doesn't softclose when parked on the level, it may still work when parked on a hill nose up. This is because the extra force/weight exerted on the tailgate slows the powered struts more, so the door closes slower. This means that even if the door is out of slight alignment the slower closing allows the catches to softclose!

Further interesting fact - dealers will express complete surprise that both tailgates soft close. But given the experience of Landrover dealers that shouldn't surprise many. Current Fleet:-

Alright, I am sure that the lower tailgate has lowered even more, the gap is more than 1 cm now. The hinges look tight, so I wonder if there is a way to adjust the length of the cables inside the door...

mine is the same. Hinges and soft close working but sits like yours 2017 Range Rover Vogue V6 Diesel
2006 Range Rover Vogue V8 Diesel - gone

I'm going to have a go at adjusting mine when the weather (and a spare set of hands) permits.

If anyone beats me to it, please report back on how you get on. Kev

Adjust, but what? How? There is no mention of the 2 holding wires in the service manual, only the actuator is described: "The lower powered tailgate is opened and closed by one tailgate actuator mounted in place of the gas strut."

As long as the hinges are tight and the tolerances are correct, what can be done? The attached document is the only place where the lower tailgate gaps are mentioned.

Firstly it'll be the top one through using the Powerfuluk video as a guide, then the bottom one afterwards. As to what to adjust....I don't know until I look at it. Even if a specific adjustment point is not designed in, optimisation may be possible. Kev

Good luck with the top part! The following document shows what to look for with the adjustment (mostly to get it to be flush at point 1 and recessed at point 2...)
