2013 E550 Small leak, clear fluid

Hey friends,

Hoping that I can get some thoughts here before bothering the local shop. I recently had this '13 E550 4matic in for an 80k mile health check & B service. While out today, I noticed some liquid dripping from the back/center of the engine bay. I've included some pictures in this album. That should also include a quick video from the driver's side, tried to angle up to see any pooling but nothing obvious. The car didn't have any issues on the drive home, and the fluid has no color/taste.

Any idea about the likely source for this? It is a warm 85* here today, so hopefully I'm not just being paranoid over condensation from the A/C

Thanks again!

Yep, same exact place we get water from four or our MB cars in the driveway...the new one...drains like a leaky toilet from the far front bumper and from the rear center.

No discernible taste. I have driven another ~50 miles with no issues, and there are no drips when the car is run without AC in the cabin - so I'm feeling confident now that it's just condensation.

If you accelerate hard, car azz sinks down, better/easier HVAC condensate water out of the 2 condensate holes.
