Two quick follow up questions for you experts regarding this issue.
I noticed the same wet floor carpet issue in the passenger side of my S8 (LHD). I've gone through the normal drain cleaning procedures for wheel-well drains, the main drain in the engine bay and the AC drains. While doing so I noticed that one of the orange drains inside the cabin had a small cut. I was under the impression that the drain goes deep behind the trans and my only option was to tackle the replacement when having the trans out. That's not what I'm reading here.
Can anyone confirm that you can, in fact, remove and reinstall the drains from inside the cabin? If anyone has pix of the actual orange drain out so I can see the shape it would be most helpful.
Also...as I read this great thread I can't help but wonder.....who are Botang and Dizzy?

I'm sure there is a story behind those names.
