Need help figuring out a coolant leak (see pic)
I noticed my coolant light came on a week or so ago, so I filled it up and didn't have any other issues until it came on again yesterday. After driving for a couple miles it went off. I topped off the coolant in the car and watched for any signs of leakage. Well I found some after pulling out of a parking spot. I took this pic, forgive the quality, and noticed liquid near what I believe is the lower radiator hose and some sort of sensor. Any ideas on what would need to be replaced? Thanks for the help E46 community.
