2021 M550i cold start rattle?
Hello,
Just curious if this rattly sounding noise is normal for 2021 M550i. It happens for the first second and then goes away. Only occurs if it’s a cold start. Not audible inside, only when remote starting and it’s been this way since I bought it (Certified pre owned). Thanks for any insight Video of Noise |

Wastegate rattle, annoying as hell and cannot believe it is normal behavior. I have the same issue.

Can’t seem to find anything for it and I’ve read it’s normal but I’m coming from an S4 that also had a “normal” rattle on start and it takes away from how good the car sounds on a cold start. Can’t escape the rattle apparently. |
