That's the issue I'm in Ireland and it's a UK diesel car with 120,000km or ~75000 miles on it. I googled this and found

1. The drain from the air conditioning blocks. Checked it, and it's clean.

2. There's some drain for the windscreen runoff is supposed to run down behind a cover in the wheel arch. We checked both wheel arches, and it isn't there on either one. Where is that on the 2006 model

I'm kind of out of ideas now. I did bring it to a citroen dealer and another garage but neither could find the issue. We heard waffle about leaves, seals, etc but all that stuff is fine. It's a clean low mileage car.

How wet? Is it only wet after rain?

Are there any rectangular holes in the wheel arch? the rubber tubes have flaps that block so they sometimes get removed altogether.

Is the drain pipe for the air con attached at the top?

The floor isn't only wet after rain, it seems wet continually. That said, it rains pretty continually in Irish winter. It's hard to be sure. It does definitely dry out some.

I was a Motorcycle mechanic in my youth and fixed my own cars as the skills are fairly transferable. But I'm disabled now. My son did the work, armed with 3 youtube videos; he didn't find either tube under the wheel arch, and eliminated the internal one. The air con tube was dry and clear. He's smart enough.
We can't find the wheel arch drains, and need to follow them down from the top, I suppose. He came away feeling it was something weird with this particular model. We saw two ways Citroen did the wheel arch drains, and we can't say which way it was done in our car.

What you describe is consistent with a blocked A/C drain.

OK - thanks. Passed it on, (all I can do) and it's nice to have a firm diagnosis. If I get success/failure, I'll post results.
