Lots of water in my spare tyre well

[IDontKnowCars]

I managed to pull the trim away from the metal today after a LOT of effort. However I am not comfortable going any further than this because of lots of electrical work behind the trim and the fact that I do not see a reasonable next step after getting to where I did to proceed even if I did have the confidence.

Having had a good look where I could for any holes or rust in the metal, I could see none and thus cannot understand where the water could be coming from. Living in a flat and not having access to a water source, I could not hose down the car at this point either meaning I was limited simply to a visual inspection of the state of the metalwork.

I made a video which is representative of what I could see on the troubled side. Is there anything anybody here can see in the video? (Put to 1080p for detail).

If all looks good in the video (Unfortunately, the progress I made was not ideal still), does anybody know the next logical steps for me to take?

The video can be found here: https://youtu.be/QGpsC7qdE9c

I have also recently bought a jack and jack stands so can now look under the car for defects (Although I don't know what I am looking for).

I was driving a Mazda 6 into the workshop last week and could hear a sloshing noise as it came to a halt, I wasn't familiar with the car and figured it must be the fuel in the tank.
Until I pulled off a heat shield from underneath the wheel well and got an unwanted shower, filled half a bucket

Where is this heat shield?

Is the lining around the wheel (Which I video near the end o the video) actually a removable part and is what you are talking about? If so, It may be worth me taking a look to see if I have water trapped here too.

My wife just punctured and I went out to help her. Upon removing the spare wheel, there must have been 2 inches of water in the rear boot well. Having searched this forum, it pointed to a rubber bung being deteriorated. Spoke to VW dealer, they wanted £550 to carry out an inspection - a holding deposit essentially. If they found the problem and I decided to get them to fix it, the £550 would have been returned and only the cost of the repair would be paid for. If I decided not to get them to do it, it would have cost me £550 for the inspection of the water damage. A dead easy fix, £5 for the replacement rear drain hose, and 15 miuntes to replace.

go through all the ingress points, one by one.

rear lights.
lock if present
glass
trunk seal
panel seams
spoiler if present
rear wiper aperture

there are only so many ways water can get in - dust everything with talcum powder and the ingress will be easy to visually identify.

I've had water ingress in my boot & front footwells in my Mk2 Focus. All caused by cracks in the seam sealant in the bulkhead (footwells) & around the boot hinge pockets.
