Hi all, looking for some advice on this I've read it can be the sunroof but I've checked the drains and they don't look blocked, is there a common fault here I can check?

Have you been driving in the rain or washing it a lot? Could be something down in the drains. There is a written process for blowing out with low pressure air.

Have you been running the air conditioner a lot? Could be the condensate drain for the AC leaking in the footwell.

AC discharge hose is plugged.

My ac is not gassed up at the moment can it still wet the carpet if the discharge tube is blocked?

No. It is a condensate drain line for when the AC is working. Did you check the other drains under the cover next to the battery, left and right side? Other sources are the sunroof drain lines on both sides.
Note - they are on both sides.

There are 4 sunroof drain lines. Also check to make sure the drain line is still properly connected to the sunroof. On one of my old VWs (which Porsche borrowed the design from for the 996) I had a flooded passenger side and it turned out that that a previous owner must have tried too hard to clean out a drain and actually popped the tube off. So, when I checked to make sure the drains were clear, they were, but what I couldn't tell was that the tube wasn't actually fully connected to the drain and a lot of water was getting out.
