E91 330D not revving (boost leak - vid?)

Post by HarisF1 » Sat May 04, 2019 6:46 pm

Hey guys, I've come across an E91 330d (2008 with M57 engine) that has a very peculiar issue. I was told that it was sluggish and upon 'testing' it I have noticed that it can barely rev up to 3000 rpm at which point it seems to lose its way and power drops off rapidly, settling around 2000 rpm. At the same time a whooshing sound can be heard. I've managed to find a bit of a clue in the following video: https://www.youtube.com/watch?v=VCdd8stZMm8

It shows the engine revving and the hose collapsing. This seems to be the EGR to Intercooler hose and I have no idea why it is in a state of vacuum. Is the hose damaged, or is there something causing negative pressure in this pipe? As it stands, the car is completely undriveable.

Any ideas?

Thanks in advance!
