This hose on my 1998 E320 concerns me because of the bulge.

Can someone please identify which hose this is, and if that is a normal shape on the hose? I would think not, as it is touching the alternator.

It leads into a part that is situated below the air filter housing, and I don't know what part that is either.

Thank you in advance!

If you have a 104 engine then I believe that the hose is apart shut off valve\air pump system!!

After looking into it some more, it seems like the suspect hose is the one that
leads to the lower part of the coolant pump, or the auxiliary coolant pump.
