Loud rattling sound(2013 x3 f25)
Hi.
First of all. I had problem with white smoke coming out from exhaust pipe and I got covered by warranty(turbo oil feed line). But there is still rattling sound when I start engine. And about my exhaust pipe, air coming out from one pipe only, the other pipe, very little amount air coming out. They are not same. is there any tip for fix it? |

Exhaust only coming out of one pipe is normal. There is a valve in the exhaust that opens and closes to control drone and sound tuning, nothing to worry about.
The rattle could be millions of things, could you get a video?

Are you talking about a chattering kind of noise on cold start up? Seems like it's normal for these engines to have a somewhat loud valvetrain, especially right after start up. Mine has done that ever since I got it at 10k miles and less than a year old. It always smooths out though but I would say it does make a bit more of a sewing machine noise than most other engines.
