Hello to all

Before you say it - I KNOW there are loads and loads of threads here, there and everywhere about water ingress into the A6 footwells!

However, I've read a load of them, and already knew to check the bulkhead / plenum area for blockages as an experienced car owner. My bulkhead is bone dry although the two plenum drains were pushed through and cleared anyway....

I've got a reasonably large patch of water in the driver's footwell only. Nowhere else. It doesn't appear to be coming into the car from the pedal box/pollen filter sort of area, as all of the carpeting above foot level is dry. There appears to be a narrow patch of wet carpet on the O/S of the driver's footwell, roughly just behind the bottom of the A-pillar. My suspicion is that it's draining into the footwell from this sort of area, which to me, points to the A-pillar/door type area.

I've got a sunroof. I'm trying to find info about how to effectively clear the drainage channels. Can anyone help with this? It was too dark to start checking around when I got in this evening. Blocked sunroof channels is Suspect No. 1

Suspect No. 2 is a blocked door drainage channels. Again, it was too dark to go poking around, so I'll be looking and checking these in the morning. I'm assuming that there are just a couple of plugs on the underside of the door? If there's anything else I should be checking/clearing, I would very much appreciate any steers!

Suspect No. 3 is the drainage channel just below the wiper mechanism (but above the bulkhead). Again, I was only in a position to whip off the main bulkhead over this evening in the dark and could see that everything was pretty dry. I did note, as an aside, that the two corners just below the windscreen and by the bonnet hinges were full of leaf crap. Are there any little drains tucked away in these corners? My research thus far suggests that I should be clearing only two drain holes in the bulkhead:

1 - The main one shown in most videos, just below the car alarm horn, roughly in the middle of the bulkhead
2 - A second one below the brake servo reservoir

Are there anymore?

I'll be vac'ing out the entire area as best as possible in the morning, but any steers again would be very much appreciated.

Finally, I was alerted initially to a watery sort of problem, by hearing a very odd and very brief "water gurgle". It was brief and lasted for about a second or two whilst driving around a corner or two this afternoon. My sons were in the car with me, and we all pointed to the centre console armrest!! (so am confused by this enormously). Does a watery gurgly noise from this sort of area in the very middle of the car mean anything to anyone? It was the sort of noise that a partially blocked drain noise makes as it's trying to drain water and air nips in to interrupt the flow - that sort of gurgle, and only everso brief.. I'm wondering if we all mis-heard and it's actually pointing, somehow, back to the sunroof?

Many thanks for any replies... I'm super-keen to get this sorted tomorrow, as I know exactly sort of damage persistent water ingress can do!

Oh, and also, the water doesn't smell of anything. One of the first jobs when I got the car was to fix the rear wash-wipe pipe that had broken in the rear quaterpanel and was ******* water onto the MMI unit area! The rear wash-wipe, as far as I can see, is working just fine, and this is in the driver's side footwell only so shouldn't be linked to that potential source of water in any case.

Suspect No. 4 - Finally, I did have other possible culprit that sprung to mind - the air-con drainage channel. Anyone know where this is please? I've recently fixed the air-con (new compressor / pressure switch), so this has been working for the last few weeks. It just occurs to me that as this wasn't working previously, and no excess water needed to be drained, that this is somehow linked? Any guidance please - much appreciated.

I am a picture person ideally. It's brilliant when people show me stuff as I find it so much easier to follow and do!!!

Finally, finally, I have noticed that the fuel filler cap area seems to capture water. It sits at the bottom and I presume is rainwater that drips in around the fuel filler flap and isn't draining. I can see what appears to be a very small, white, something or other right at the bottom below the actual fuel tank filler neck. It's very small and I had to clear a fair bit of oily crud to even find it. However, having poked some very sharp narrow objects into it, it's not draining any of the water that's sitting there. What am I missing here?
