I was looking at that hose the other day. Couldn't see where it went without taking the upper intake off. It seemed to run straight back under the upper intake, I tugged on it a few times to see if any other hoses moved around the engine bay but I didn't see anything. If I get a chance to get under the car this weekend I'll try and see where it goes. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
