B6 A4 passenger footwell paddling pool!
Discussion
I'm sure I've read that this is common and I'm sure someone here will soon point me in the right direction....
It's not the door seals, as it's dripping down behind the glove compartment, so I'm guessing a bulkhead grommet or pollen filter area. I've just re-seated the pollen filter lid, but it seemed dry inside. Where eale should I be looking? Only had the car a couple of weeks and I think we've just had the first major downpour since. I'd rather the rain stayed on the outside though!
Edited to say that having 'Googled' it it seems extremely common and is probably down to a blocked drain hole under the battery. A job for the weekend then, hopefully before any electrics get fried!

Just pull the grommit out from under the bulk head. The net seems to advise battery removal but it can be done in seconds just reaching under the bulk head, just next to the steering rack towards the passenger side.
Thanks, I'll give that a go.Just peered in under the battery and there's no sign of water, but the I suppose it's all in my footwell now.
It was the air con venting pipe in my S4.
Here is the thread from 6 yrs ago, it might help. http://www.tyresmoke.net/forum/audi-a4-s4-cabrio/9...

Poked around some more.
Removed the passenger side plenum gromet (reached in from engine area, without the need to remove the battery etc). It was clear. No crud or rush of water. So it's not that.
Removedthe glove compartment and traced it to the underside of the blower motor housing, where there are drips coming from what appears to be a small slot shaped opening in the plastic casing. So I assume there is water behind this in the collected in the bottom of the motor housing. Would this be getting in via the pollen filter?
I took the scuttle cover off, again and the pollen filter lid, again. The filter itlself is dry. The lid is designed with an overhang, so water landing onnit should run off, not in. I see the pollen filter box is somehow sealed to the bulkhead with a foam strip. This feels dry around its circumference, but I'm guessing this is the likely culprit?
I'll also check out the a/c condensate drain.

The drain will be the issue I reckon.
Mine was dripping from the blower, it backs up and over flows.
Easy test.....run air con....look under car, around the passenger footwell, for the condensate dropping onto the floor.
No water, then that's the issue.
Remove pipe from the top/in line connector, trace it back once you pull te carpet back (don't blow it from the bottom), and I connected an air line, but a bike pump or air bed pump should do it.
Re connect and watch the water flow out of the car.....

It certainly looks to be this. I've given up for now as it's got dark and I can't pull the carpet back enough to expose the drain pipe. I'm hoping I don't need the strip too much on the centre console trim to do this.Mine was dripping from the blower, it backs up and over flows.

Job done - I hope!
After wrestling with the carpet for a while I managed to access the condensate drain pipe, which was indeed full of crud at the top right angle bend. Gave it all a good clean and blow through and re-assembled.
While I was tinkering I also removed the pollen filter housing and re-seated it with some extra sealant around the outer edge. With that done, the a/c drain pipe cleared and the scuttle/plenum drain grommets removed hopefully all bases are covered and the inside will stay dry. Fingers crossed!
Now I just need to dry the carpet out. Think I'll run a dehumidifier in there with the windows closed for a few hours and see how much that sucks out.
