Sorry you were not able to fix the leak. Let us know what the dealer does to make the repair.Unfortunately, mine doesn't appear to be the roof drains. I tried stuffing some braided weed eater line, and some fairly stiff clothes line in from the bottom, but ended up about a foot short of getting it all the way to the rear panoramic roof drains (just a guess, by trying to measure outside the car),but I did shoot some air at about 40 psi, and could hear it in the roof channel, so I know it's not completely blocked. I'm scheduled to take it in to the dealer tomorrow morning. Fortunately, I have a liner in the rear, that seems to capture the water, so it's not draining into the spare tire well. It's raining pretty good today, so it ought to be full when I take it to the dealer in the morning .
