Is anyone else getting rattling noises coming from the left side of the exhaust on a cold start had it replaced once from BMW saying the baffles has gone but the new exhaust system they put on only 6months old

Yeah I've got the same issue, but mine (M140i) does it not all the time, maybe three/four times a week.

I've noticed that it makes it especially after short time stops, for example when you stop the engine for refueling, and then you go.

For me it's not a real problem, as both M135i/40i and also the M2XX models have this "matter".

Mine happens on a cold start worst is of a morning, sounds like the heat shield rattling but iv checked not that, but soon as it warms up An the flap opens it stops, looks like another trip to the dealership
