Hello fellow enthusiasts,


I´ve been lurking in this forum for a while now, but haven´t posted until now. Everything here has been a wealth of information.


Luckily...so far my 01 4.4 has had little problems, mostly for the preventative measures and keeping an eye on the major issues others had had here.


My X5 has returned from the dealership, after they have replaced my rear air suspension height sensor.
I do most of my repairs, unless it´s something like the suspension where it had to be re-programed.


So my SA informed me that my ¨intake crossover pipe and intake seals¨ were leaking air into the engine. So far my car has not thrown any codes regarding this. Even worse news was that the repair would cost 1200 dollars.


I declined the repair at the moment, for after trying to get a description from the SA I still could not understand what this part was.


So I´ve been looking at the x5 microfiche and can not find the part my SA was talking about, from his description, it was a pipe that transferred air from one side of the manifold from the other?


So I took a look under the hood and the only cracked/ leaking part was one of my oil separator hose.


Both were very soft, so I ordered a new set of hoses and oil separator valve.


But I´m still stumpped on this. Could my SA have mis-named the part that is damaged, or have I uncovered another ailment with the car?


My question for you guys is, do any of you know what the intake crossover pipe is? Or have had it replaced?


Thanks in advance.
