Water Stains on C-Pillar - Sunroof Drain Leak?
Car: 2001 S4
I've done a search and see that the sunroof drains, or cracked sunroof tray can lead to water stains at the C-pillar.
Does anyone have any pictures or directions on how I can check these? I've opened the sunroof and tried peering down to the back to see if I can see anything clogging the drains, but can't really see that far back.
Anyone have instructions on how to pop the C-pillar cover off, so I can try and see the drains from the backside...or know where they drain to, so I can try to blow some air through the holes, from the bottom up?
I don't think the drain holes are plugged since the car is parked indoor and when I looked, the sunroof tray was clean...but I figured better check. Aside from that...are the Audis known for bad window seals from the factory?
Thanks for any help anyone can provide on this issue...pictures appreciated.

Yeah I have it now on both c pillars
I've heard it's most likely the sunroof drains. I'm taking mine to a detail/auto body shop near me and they can diagnose.
I'd do it myself but with work keeping me busy just can't and the stains are annoying the hell out of me.
If it is the drains, probably take a couple hours to resolve so the bill shouldn't be too bad.
Only other option it could be would be the back glass seals leaking..but in looking at where the stain starts, I have a hard time believing that.
