[RoverSonora]

I have a full size 2007 RR HSE.

What are the most common locations to have a leak into the rear trunk right side, where the amplifier, nav CD unit, etc all live?

In my searches this seems like a common problem - that is, stereo electronics getting fried from water ingress. There is also a Land Rover TSB on water ingress into this area. The "water shedder" (plastic sheeting) is recommended.

I JUST spent $400 replacing my amplifier that was fried and the stereo worked for 24hours before it rained again! Small amount of water dripping directly on the amplifier and bluetooth phone system.

I have the water shedder installed (must have been done by a previous owner at some point). Still gets on the amplifier.

I want to fix this darn problem.What are the top 2, 3, 4, 5 places the water could be getting in here?

Mine was caused by the rubber seal that goes round the boot.
I have explained this on a previous post.

If you lift the flap that goes between the boot and the lower tail gate is it damp, mine was, did the new seal and now its dry as a bone.

Hope you find the issue soon.

You might want to recalibrate your sun roof. It can go out of calibration if the battery is disconnected or even just allowed to get very low. The sun roof can look closed but be just slightly open and heavy rain can exceed the capacity of the sun roof drain. the excess water can flow across the headliner and down inside the left rear pillar. In knew this could happen and forget when I had my battery replaced. The very next day it peed down and I got to experience the thunder of water in the amplifier. On checking the sun roof needed registration. I could blame the autoshop that installed the battery but it was my fault. I should have checked. I knew it could happen. Now you do too.

Register the sunroof by just pushing up on the button and holding it for around 30 seconds. You'll hear it move or at least click. Job done.

Other issues on older L322s:

Rear side window seals at times leak.

If anyone has removed the D Pillar covers there are little rubber boots that go into the holes before the plastic push rivets go in (just like A pillar covers) on the inner sides. If those are not installed water can leak in through there as well.

Loose roof antenna can cause seepage.

As mentioned boot/hatch seal can leak.

The "water shredder" only partially works as water can still work its way and drip inside the shedder itself.

A DIY datafoo solution is to put a large zip lock bag over the nav with a slit cut out to access the DVD disc if necessary (opening towards the back but closed except to allow wiring thru). Another over the Bluetooth. Some of the lower modules you cant cover due to heat buildup.

Your amp is mounted to the subwoofer if I'm not mistaken so the water was likely rear side windows and an area the water shedder doesn't cover anyway. My understanding is a window R+R or reseal attempt is required.

The best way to source, and then cure, any leak(s) on your car is to use a smoke machine to help identify openings/gaps allowing water ingress to the left rear compartment.

There are plenty of you-tube videos on this. You'll place the smoke machine INSIDE the vehicle, turn it on and then stand OUTSIDE the vehicle and detect whisps (or clouds) of smoke leaking from within the car.

Don't be surprised if you discover more than one [small] leak.

An inexpensive smoke machine can be had for around $60 or you can even try and make one for around $15. You may also be able to rent one from a party supply store.
