I chased wet carpets for a couple of months on my wife's 04 last summer. Pulled pillars, dropped headliner enough to see the nipples/adapters to the drain hose and tested front and rear sunroof drains. NADA. I had fixed the stupid adapter piece from the drain nipple to the hose with RTV and small hose clamps on my Audi, so I was used to the drill.
Finally went to local dealer, with a great relentless tech. He found the bad seals at the top of the rear hatch opening near the hinges. There are plastic plates with awful foam seals that rot. The water worked its way down to the front carpets. Cost me $300. It was worth every penny.
