Coolant leak from front engine hose

My e92 328i is leaking coolant (minor) from a hose in front of the engine, I think the gasket is the problem but I need to know the name of the hose or part to get the gasket asap, I'm attaching pictures from the hose

are you sure this is a leak?....great picture, but its almost too close to see enough around the area...I would clean this first, then watch for moisture....I see some dirt...but are there any water stains below the hose?

Is the dark area soaked dirt and grime, or just dark?

That's called dirt. Coolant is a liquid.

Coolant dries white and looks like a salty buildup. If it's a really heavy leak it may look blue. I just see dirt stick to something with no true evidence that it's coolant.

I would thoroughly clean and observe all over again.

I dont think is coolant leak. Its problably oil coming from either oil filter gasket or valve cover.

It could be coming from the coolant temp sensor right above the hose. Clean it up and see if it happens again. Do the easy stuff first.

Well, first of all, thanks a lot for all your replies, the photo was taken that way to find out the name of the hose or part attached to, the leak is visible just under the hose, and yes it's like salty build up, I just cleaned the area yesterday and do a visual inspection today and no more salty build up.

Well, I got 2 more photos ! and it's confirmed, it's leaking, very minor, you can't see it, but the base of the hose is leaking underneath and of course it's coolant !
