Went under the car to check if the engine mount had a leak. Well, there was no leak there, but the car had leaks at a few places and I'm trying to figure out what needs to be replaced.

The bottom one appears to be the ATF cooler line - another version is from the Bentley manual, which is return/supply from the radiator.

The top leak behind the belt appears to be coming from the power steering pump. Any usual suspects on what causes the leak here - power steering pump, Banjo bolt, or the pressure hose (4F0-422-893-H)?

Since I am no expert, please correct me if my identification of the parts is incorrect

Thank you Royclark - this is very helpful! Appreciate your help! Looks like my return hose going to the reservior needs to be replaced.

Usually its just those awful hose clamps. Cut it off, and double clamp it with 2 worm gear clamps. Unless its swollen real bad, I cant tell from the picture.
