I am confused by what I am finding. I went to start with the rear drains in the saloon boot but I am puzzled the drain pipe connections look brand new and clean.

A Rover 75 owner had same problem here in 2013 and gave up trying to fix it

The driver side rear passenger carpet is already unhooked free from by the sill by a previous owner and I soon had a gallon of water in my wet vacuum cleaner. Water keeps reappearing from under the carpet.

I put my old style square Thule Universal roof bars with a 6' x 4' (1.8m x 1.5m) tarp wrapped around the bars to keep rain off the sunroof.

Hi Ed.
Don't be that chap above, sunroof leak drains can and have been solved with great success it's just a case of time and effort.

I presume you have a saloon so the rear ones are easy accessible, mine was a Tourer which is even more work to reach the rear drains, but most of the time it's the fronts that cause the problem, anyways pull out the tube and you will see it is only just inside by about 5/7mm which is not good from factory.

The same goes for the front which are the real problem, once water gets in it goes under the carpet, and because of the sponge it can take years before the water shows above the surface of the carpet, usually first sign is just below the seat belt anchorage area little dip.

You can use tip of sealant which would do the same job, but the ones i used have barbs so they hold in.

The water by then because of the floor pan design it flows to the rear and eventually fill all the floor pan.
You will also need to peel back the front wheel arch liner and cut a bit off the sunroof outlet tubes as here below.

Don't give up at the moment clean what you can out without removing the carpets then come summer get them out, and dry it out completely, or if you have a carpet from another car replace it with that.

Thanks Steve, On my previous saloon (no sunroof) I had no option but to take the carpet/seats out and clean all up but did so with the car off road for a few months.

On this recent saloon the past owners have sued those Halfords white drain pipe connectors in the boot and so I am suspect they will have done the usual sunroof clean the tubes and the rain water leak is a little more unusual such as possibly the panel seams (drivers side of car to roof) leaking to only to the drivers side rear footwell. There is constant heavy rain here so progress is slowed

UPDATE - with water levels inside the car going down with regular wet vacuum the electrics seem normal (but I still disconnect the battery in case). SO If I can stop the leaks all will be ok in due course.

And this might explain the electrical issues. Leaking front sunroof drains, on the drivers side can get water into both the light switch module, and the immobiliser. Immo can be seen in one of Steves pictures. It's really important to check, especially the light switch, as water in there can cause it to 'overheat' which you REALLY don't want. Do that especially the light switch, before connecting the battery again.
