We don't think it is that. 1. He already had it replaced, 2. I have it on my 1M (and my 1M is the N54 engine - so it has a completely different turbo setup - 2 vs. 1). I really suspect it is something to do with the air intake. I would try removing the air cleaner maybe?
I have the same thing on my diesel. The noise is there, but it's not that loud yet, but it is getting louder and more frequent. I have 1,5 years left of my warranty, so I'm waiting for it to get more "visible" for the BMW to do something about it.
