N18 – Cold Start Exhaust Rattle Noise (Turbo Wastegate)
My '11 S Clubman has <1K Miles. Owned it all of 11 days. I started the car this weekend with the door open, and heard a rattling noise. Lasted 30sec-1min thereabouts, than was gone. I thought, "uh-oh death rattle, but already?"
Checked for it again this morning, and sure enough, 30-60sec, then gone.
I called local dealership, the SA said, this is normal , his S does same thing, it's the turbo wastegate making the noise.
Of course, I didn't believe him, searched some more in forums and on the net, found the attached SI.
1) Has anyone else noticed this issue?
2) If you have, is there a fix other than that I have heard, and then read? ("Live with it")
Is it me, or should a brand new car not make a noise on startup?
Cheers,

This a new item on the N18. The waste gate stays open at idle to help heat up the cat faster. The waste gate cup is what you hear rattling.
What the SA at the dealer said is correct. Mini/BMW even thought enough of this item to discus it during qualification on this engine.

I think this really is pretty common, mine makes that noise on startup too, but then again, my waste gate is hanging open, and needs fixed.
there is a warranty extension on it, 10 yrs 120K, mine is at Mini right now for it.
apparently, it is a well known issue stemming from the proximity to the exhaust manifold, with the heat causing the waste gate to fail.
It might be worth getting it looked at
