Extra drain holes apart from under battery

[Paulcurtis]

Are there any extra drain holes on the passenger side of a A6. The one under the battery is total clear and my carpets are soaking wet on the passenger side , 20mmm of water laying in the rear foot well. have tried to dry out using wet and dry vac. Any advise please?

There's also a drain for moisture from the a/c in the passenger footwell area and the rear washer fluid (if avant) pipe runs along the passenger side. Washer fluid leakage is common.

Thank you, it is a car not avant, where will I find this drain please. It has not been used for the last 3 months, as I use in winter, how would it fill if not being used?

So it's a saloon then, no washer hose, the ac drain is behind the glovebox to the right. More likely though is water ingress through the pollen filter housing which is directly above the passenger footwell area in the engine bay, under the scuttle. Maybe check that rates for a build up of leaves & crud?

Check to see if your engine coolant missing

The pollen filter is completely dry, There is a fan type devices under the filter and this spins freely. there are no leaves or rubbish under the filter?

Header tank full !

What about the condition of the pollen filter seal?, it's made of foam and turns to sludge. I resealed mine with stixall.

I'm all out of ideas other than that, is there a sunroof perchance? (Drain holes/hoses clogged), or perished door seals (not sure this'd be very likely anyhow)..., maybe someone else will have more suggestions?

My pollen filter does not have a cove on top, is this the problem, no sunroof,

There should be a black cover across the whole plenum chamber. Covers battery, brake servo, ECU, pollen filter etc. You should need to pull the rubber seal off the lip to get it off? Without this, I imagine water would run straight off the windscreen and into pollen filter like a funnel...
