I'm believe that's the coolant recovery connector, I don't know the part number you may need to call your local dealer to get that information. I think I remember seeing a couple threads on here from other folks having the same issue, I'll try to find them and see if they are of any help.

I found a couple threads with similar issues, but not sure if they'll be much help.

I'm sure it won't be too long before one of the resident gearheads chimes in soon with their input.
