Default Sunroof, scuttle, sunroof & A/C drains?

Peering around under the bonnet earlier today I noticed what looked like water pooling on the n/s/f scuttle adjacent to the bonnet damper under the plastics through a small gap illuminated by the torch on my iPhone!

I would have thought with the various models, revisions etc. that Audi might have actually solved the problem by now!

So before anything untoward happens where are the drains located on the D4?

Is it like my D3 where the drains exit behind the wheel arch liners?

Planning ahead it would be good not only to clean the scuttle drains but sunroof drains also as I have two sunroofs on this car!

And not wishing to get wet carpets is it any easier to access the a/c drains on the D4 than it was on earlier models?

Thanks & kind regards,
-=Glyn=-

Just noticed I posted a similar question in the Engine Bay forum on 25th August but did not get a reply!

Hopefully better luck with this one...

Thanks & kind regards,

VAG just don't seem to have got this right in 20 years, it seems to affect all models, I wonder if Bentleys are the same?

OK what about Bugatti?

Default Audi + drains = problems

There's loads of reports of this with the new e-tron as well, so it's not just their "traditional" models

The mind boggles as to the implications of this happening on an EV. Considering the issues most of us have experienced with our cars on water ingress, you'd think they'd spend a few more euros trying to design out these problems.

I wasn't sure if you meant for the D3 or D4, so I've provided both sets. The sunroof one looks identical in both (the illustration only shows two, but they're mirrored on other side).

Thanks for that! How is it to access for the D4s?
