Jmillard85 Posted May 21, 2017 Report Share Posted May 21, 2017 Hi I've recently been having a bit of trouble where my 2003 318i keeps revving itself while I'm idle and occasionly cutting out. I read it was likely a vacuum leak so today while inspecting I found a large whole where I have done the small circle in the picture. Could someone please tell me what this part is officially called so I can get one ordered. Many thanks. Quote Link to comment Share on other sites More sharing options...
ibrahimx2001 Posted May 21, 2017 Report Share Posted May 21, 2017 Is that not the pipe that goes into the airbox? Quote Link to comment Share on other sites More sharing options...
