[s-cars] rear sunroof drains

[Keith Maddock]

Every once in a while, after the S4 sits in the rain for a bit, I'll
drive away and get a small shower from the sunroof when I brake.  It
comes in from around the sunroof control panel.

I've tested the front drains and they drain well enough - so I imagine
the rear drains are what are clogged.  So the water collects in the
back and then when I brake, it sloshes forwards and the front drains
cant drain fast enough.

Does anyone know where the rear drains come out?

Thanks,
Keith
