Hello everyone, first time posting

Can someone please help me identify the hose that goes downward in this pic? This is my daughter’s 2011 328i. Thanks

Have you verified that's what is actually leaking? The fitting that it is connected to is the more common failure point.

In any case, if you use realoem.com, you can put in the VIN and get whatever part numbers you need from the diagrams.

The hose you are looking for is on the heating and cooling diagrams. For my car it's part number 64219178427, but you should verify that with your own VIN.

That's the heater core return hose. Look on realoem.com in the HVAC drill down. Look for my DIY on replacing the cooling system hoses, I go over in detail on replacing all the coolant hoses on the N52 manual trans. That hose is the same regardless of transmission type.
