Hi, so I recently purchased a 316i, 2015-2016. On test drive I didn't recognise any issues etc.... when I took it out the next day, I heard a noise when I put my foot down so took it to a garage. They advised that one of my hoses from the turbo was collapsing when I hard revved the car. I have no turbo sound at all so seems that the collapsing pipe is preventing the turbo from working? The pipe in question runs from the turbo to what I think is the radiator. Mechanic couldn't really tell me much as he said he doesn't have much experience with the newer engines so that didn't help much. Car doesn't smoke and hasn't lost power as far as I can tell. Any ideas what the problem could be here?
