because I'm doing my annual maintenance on my '95 530i and I've got this hose that runs out of the air box to somewhere down in the depths of the front, right-side of the engine compartment and it's got a gash in it (and has for awhile). I looked at the drawings at Real OEM and even using my VIN, I can't locate what this hose is or where it's going to and what it could be doing while seemingly not suffering from its gash. Please, educate me.
