2004 X5 E53 vacuum line
Hi All,
My X5 was getting the error codes that both bank O2 sensors were trying to adapt beyond limits. This immediately led me to believe that there was a vacuum leak. Lo and behold as I was began searching, there was a vacuum line disconnected. It is the vacuum line that is attached to the dipstick tube. Does anyone know where that connects to? I have tried looking but cannot see any fittings that look like a vacuum hose fitting?
