In that case could either be blocked sunroof drain, blocked scuttle drain or windscreen leak

Either side of the tunnel up nearly as high as the top as the footrest but back towards the driver by about 9 inches as per pictures for drivers footwell. The other side is reflected on the other side of the transmission tunnel but same position

Thanks for your help guys, going to stick it in the garage and investigate when i have time, if it is the ones you're talking about, is it a case of just emptying the water in there, or did you use some compressed air or something to try and unblock wherever it is blocking from?

Well finally had time today to try and source the issue and sort it.
My headlining was damp,so the culprit was a blocked right sunroof drain, luckily my dad has an air compressor in his garage so i soon had it unblocked, was just a few old manky looking leaves that came out.
Luckily water is running freely now and its raining again so time will tell.

HI All,

Can I urge caution when using garage air compressors to clear out the drains. If they are extremely blocked a big blast of air could blow the drain pipes. It is much better to try to access the end of the drain plug have a look there and see how clogged it is.

I bought a hand weed killer pump sprayer (the ones with the srap on them) from I think Aldi or LIdl, took the spray head off which leaves the brass tube. This actually fits perfectly into the drain hole in the sunroof. Pump up some pressure, not too mad and that'll drain it. I use warm/hot water with some mild detergent until i see it is running clear. I just keep it in the garage and i do it every now and then...

Good luck with the drain cleaning...i must go and do mine again soon...

Tonight, I found my front passengers' and drivers' under-carpet insulation was completely wet, front to back, left to right - no outward signs.
It was the A/C drains as in Architex_mA8tey's post #27.
When unplugging them water rushed into an IKEA bag I thankfully held underneath.

I blew them out with an old CO2 fire extinguisher linked to some 1/2" clear hose. I will flush with hot water and ammonia tomorrow and make sure I can see it coming out underneath the car.

I found this when removing the rear footwell heaters which were wet.

Now have a fan heater blowing into the hole where the footwell heaters were mounted.
Will see how well it has dried overnight in the morning and do the other side.

Here is the water, it is full of mould.
