Coolant leak ... need help ID'ing

Hey all need help identifying a leaking part on my '13 Q5 2.0
Hope photos work. It's located on the driver side below one of the air hoses and near what I'm assuming is the water pump (but not sure if it is the pump itself)
It nearly drained they reservoir in 2-3 days. I initially thought it was due to a loose cap, but it's slowly dripping.

See photos of area and a really not so great photo of the "wet spot."

General area in bay:

Under these hoses:

I think I can get to it if I remove this upper and torque the bolts- but I am not sure what I'm torquing.

Here's the part. It has a sensor or power running to it. I had to hold my phone by two fingers to get a shot this "good"
