I've got a drip from my 2003 A4 Cab 3.0 that's got me stumped, and I'm hoping someone here may have some idea what's causing it.

It's actually two drips, spaced evenly about 20 inches apart, stadling both sides of the car's lengthwise centerline, about 15 inches behind the doors' leading edges. The drip is a waxy substance, that has no petroleum smell to it. It only occurs when the car is parked at an upward incline on my driveway, with the AC running on a 100-degree day. It drips maybe 5 drops in 2-3 minutes. It's never dripped anything inside the garage, parked level.

I can't think of any mechanical gear located in that area that would leak something like melted wax. I can't remember reading any posts from other A4 owners on an issue like this in the 6-years I've been on this forum.

busted engine mounts?

I don't think there's enough goop to run down the chassis.

It's colorless, odorless, and is unlike anything I remember seeing drip under a vehicle. Also, it seems to be stopping on its own.

The car's not giving any signs of bad engine mounts.
