L405 Tailgate Issue

Hi all, hoping for some sage advice
I have just recently joined the ranks of RR owners and have encountered my first hiccup.
I have been getting a low battery warning, which normally goes away after I drive the car for a bit.
Couple of days back, I couldn't open the top tailgate. It unlatches and then latches without lifting.
I can force it up, but it keeps trying to close and won't stay in place - almost like its stuck in 'close mode'
I have driven it for a couple of hours today hoping it might fix the issue; and have tried reset on the tailgate lid - but I get several beeps rather than the single confirmation beep (and there is no power at all to lower tailgate at mo)
Is this a low battery issue? where after sometime it disables stuff?
or something else...there seems to be little info I can find on a tailgate that wants to close only.

Welcome.

Not many 405 owners here but worth posting in the range rover section. Range Rover | LandyZone - Land Rover Forum
Is the battery original? if so, it would be the first place to start, low battery was the beginning of ours being toast. If the upper tailgate thinks its locked the lower will not operate (I fink)
Most LR products suffer with water problems do you have any leaks.

Hi. Thanks. Have posted there too.
I think battery is original but will take a closer look tomorrow and test /charge it outside of the vehicle.
Maybe taking it out might reset something.
No leaks I can see or find - no sunroofs

Hello and welcome

Quick (and a little embarrassing) update. Charged battery and no change; the tester I had (topdon) told me to replace the battery. So I popped to a local garage to arrange that. When we came to change the battery, I was holding the tailgate up until we could prop it up and noticed that one of the struts had popped off. So we took it off and refitted. Voila! It all started working again.
The apparent closing action was because one strut couldn't hold the weight of the tailgate (which is quite considerable because of the glass, motor, etc). The garage tested the battery with their meter and no battery change required (I was happy to replace if required).
No charge from the garage, but I gave the technician a drink for his time and refitting the strut.
Where did diagnosis go wrong?
1. I assumed as failure coincided with low battery warning, that the two were related and went to solution the low battery as cause.
2. I didn't look at the basics - hinges and struts.
It took a different position and two sets of eyes to see the issue, but now I won't forget it
