    Where abouts are the rain drain located on the B7's?

    If its been raining I get a sloshing noise when I corner so I'm guessing one or all of them are blocked.

    Have a look in the plenum chamber under where the battery sits. There are drains there that block and cause the symptoms you are describing.Most folk seem to take the drain bungs/grommets out and leave them out to prevent water collecting .

    I had this on my a4, like you say, water sloshing on cornering then entered the car under the passenger footwell. Pop the rubber bung under the battery and leave it out...but do it ASAP. I left mine for a bit and ended up flooding the passenger footwell after very heavy rain and needed a new comfort control module, which sits under there....cost me a few hunderd quid for the complete job.
