Wastegate Rattle?

JSY217c · 05-29-2015, 04:56 PM

Does the 2014 & 2015 235i have the wastegate rattle? I've read that the N55 engine has the rattle but haven't seen any posts on this forum about it except this one.

Hmm, I wonder if this is what I'm hearing. I started hearing something a few weeks ago. Not sure if I just didn't notice it before because it's not loud and really not noticeable if I have the radio up.

I have the ZF8 auto trans and when accelerating in gear 2 and let off the gas is when I hear this sound/rattle/vibration. I don't hear it if the car is parked and I rev the engine.

Is this something I should have the dealer look at?

The only rattle I hear is head marbles.

I have wastegate rattle with my current Hyundai Genesis Coupe 2.0T. It rattles so loud and it's one of the reasons why I'm selling it for the 235i. Hyundai says it's normal and they won't fix it. When I test drove the 235i I don't think I heard any rattles, or maybe I didn't listen carefully. I really hope there is no wastegate rattle issues... But if there is I hope there is a fix for it.

My engine cover rattles at times, check that before assuming its the wastegate. The rubber grommets on the engine cover are pretty crappy.

Can anyone please confirm this? at the end of revs at 3:15 you can hear some sort of rattle noise. Is that the wastegate rattle?
