Sorry for bringing up an old thread but is this fix applicable to the X5 3.0SD MSport 2008/2009 model, as I too have a very similar situation with the red rubber hose covered in oil. Also I have noticed that it is a bit oily around the oil filler neck area. What could be causing this?
Changing the seals should be straight forward so not worried about doing that but why is the oil going through that pipe anyway. I may be wrong but should this pipe only have air going through it? Please can somebody clarify this for me.
