Water Leak in boot

Hello New to the forum and have read all I can but can't find solution can you help?

Range Rover L322 2008 3.6TDV8
I know this subject has been covered many times but I still can't find the problem.
Details as follows

Water in the spare wheel
I know it's coming from more than one place. This forum helped me solve one of them and that was taking off the rear bumper cover removing the crash bar and sealing the complete area. This has now stopped the water coming in via the crash bar bolt heads.
However I still have water coming in between the seams at the back of the boot. The carpet is not wet. I think it's coming down the pillars rather than from the tailgate but can't be sure.
So Far I have tried watering the car for half an hour but as it takes ages for the water to start coming in this has proved inconclusive. I can see signs of water (not much) in both rear corners but it seems to travel along between the inner and outer panels along the bottom of the boot then seep out between the welds into the boot.
I have replaced the boot seal
Panel sealed all of the seams (inboard of the top hinges and mid way down and near the rear lights)
I have also removed both tailgate hinges (one at a time and Panel sealed under these).
I have also put mastic on the roof bar mounts.
Tested the sunroof drains and water comes out under the car from all 4 pipes.

From what I can see on the forum the best chance I have now is side windows?
But I can't find any info on what to do / what people have done? Can the trim be removed on the outside?
Should I try a thin bead of "seak n seal" around both rear windows?

Any other thoughts would be appreciated.
I think my car has had this problem for a long time if not from new. I have the rain cover over the Electrics on the left side and signs that people have tried to fix it in the past.

Thanks

A light dusting of talc in as many places as you can can help to find the origin of a leak. Mine was coming in either side where the brackets for the bar you mention fold over the top edge

Thanks Holiday Chicken
I had already removed the crash bar and made sure following your earlier post that I put Panel seal along the top edge. As well as over the bolt mounts and between the crash bar and towbar etc. I am fairly confident that that leak has been stopped as I no longer see any signs of water around the 8 bolts inside the car.
I have tried your talc suggestion today although as the water seems to come from inside one of the double skinned area I'm not sure it will help. As I can't get talc where I would ideally like to put it.
Today I have taken off the exterior "D" pillar trims and checked behind these even sealing around the pop on mounting points. I was also been able with these removed to put a bead of panel seal down the rear sides of the back windows.
Also I have taken off the roof channels and put sealent over the channel mounting points and roof rack mounts.
I did notice today that it's damp (not really wet) in both rear corners (with the cover trims removed) but not really wet. Having said that it appears the corners are slightly higher than the central boot area (perhaps this is an illusion). What I can see is a large puddle of water slightly to the left of centre in the boot through the holes between the inner and outer vertical panels at the rear of the boot. This water then eventually runs to the side through the seam and into the spare wheel well. It takes so long to actually start leaking that even after 15 - 20 minutes of the hose I see nothing. But leaving it overnight when it's wet (on the flat) in the morning a decent amount of water is in the wheel well.

It's not due to rain for a few days now so time will tell.

I'm new to Range Rovers (had it just over a month) and love the car, Accepting this is nearly 10 years old it is not really acceptable. I think it's been doing it for years perhaps from new. Mine has the Land Rover fix of fitting a water jacket over the electronics but they are still subjected to constant damp etc. What a laughable solution that is!

So far I have had the gearbox oil changed (using Terrain Vehicles excellent gearbox flush service) Also changed the oils in the Transfer box front and rear diffs and engine.

Any further advice is appreciated. I will let you know next time it rains if I have made any further progress. However I'm running out of ideas as now feel I have done all I can. If I could find where it's coming from it would help.
Thanks

If you want a plain Jane reliable 4x4 then it’s a Toyota but if you want a challenge then the Range Rover is for you, it’s not all pain

I think these are going to prove to be very wise words. When running well they are the best but .....

I have an unrelated problem I wonder if you have come across or can advise on.
Again 2008 3.6TDV8
If I set the climate control (both sides) 1 notch up from minimum on the auto setting. It gets too hot in the car. If I set it to minimum it gets too cold. It's not regulating correctly
Having read the forum I have checked the interior sensor fan is spinning and made sure no dust is blocking it. Have you come across this before / any thoughts?

I'm not sure on the later models, you could try having a google about blend motors, i have heard that mentioned in the past or somebody will chime in.
I tried using my climate control but it seemed to be erratic so i just set the heater to warm and then use the wheel to blow cooler out of the top vents but i don't know how the later models work.

Hi John,
Welcome to the fold. I joined in October 2016 with my 2005 Supercharged and as our friend says it has to be regarded as a constantly evolving puzzle. That said I must apologise for my absence of late as "touch wood" my family have been thoroughly enjoying our Black Beauty every day since overcoming a very annoying battery drain caused by the car not going to sleep. My solution was to disconnect the battery every night. After a number of days (I lost count) I tried the remote lock and presto it actually worked. That was back in April last year and it hasn't lost a single volt since.

What has this to do with moisture? Well, once you can drive it every day it stays naturally aired out. It also gave me time to install two small reusable dehumidifiers (plug in to dry out, from Halfords). They catch everything else that lingers in the boot and one in the cabin. I also have a small microwavable pad that now sits on top of the DVD module that needs a ping every two to three weeks. This was initially bought to dry out the glove box fuse box as this was almost dripping wet.

Bottom line is, if you don't live in California, these are essential measures along with always using the air con to dry the Great British air.

Regarding the water in the tyre well, I am also on your quest and have to report that I can use a local automatic car wash repeatedly without a drop in the boot. However, one trip to the local hand wash or jet wash myself and half a cupful in the boot..!! I have located the main water path in, along the wire bundle entering the boot from the box section behind the rear bumper. I will follow your lead into the various closed sections and report if I get any closer to a real solution.

Thanks for reading to the end, hope it is as supportive as useful. Looking forward to spending more time back online.

Thanks for your help and advice much appreciated. I will post a more specific question once I am sure of all of the heating perameters

Thanks for the input and thoughts Tricky. I did check the cable bundle you mention and the one for the tow bar wiring loom. Both seemed good.
To be honest after my last round of taking off the outer rear side trims and the roof rack channels and sealing all of these. If I don't find it and short of learning something from the talc I put down ( but this I can't really use effectively as where I need to see is between the skins) I am at a loss. As I feel I have sealed every joint and every possible water ingress point. If it does leak again and it's not due to rain for a good few days. I'm going to go back to basics and try soaking the car from say the bumper downwards for as long as possible. If no water then gradually move higher until I see something. Although I have tried this in the past and as the water seems to take so long to show It's not easy. Time will tell.
Thanks again.
