Just a heads up that pipe 2 in the link above was rubbing up against a pulley and eventually caused it to split today
As I was driving up the motorway I suddenly got a drive train fault come up and go away again which I thought was wired as it didn't tell to pull over immediately and also said I didn't need roadside assistance so I continued and only when I got of the motorway could I hear whoosh noise on acceleration and then on further inspection at my destination did I discover pipe 2 was split. The split was exactly where the pulley was. My car is a 520d so worth checking to see if it happening to anyone else's car.
