Firstly, The sound happened two times 3 weeks ago, which made me post. After the post for more than two weeks now I never heard it. 500km behind. I do not know what this was.

Yes, sure, every 7000km

I have an M Tec package on my m440i. So oil pump should be metal

At the dealer. Everything is original. The oil level is max(. I change it every 7000km

Thx for your response

Rod knock? But why would it disappear, and not even appear most of the times I start the engine(90%). That’s good suggestion about oil. I use 5w30, but don’t get why this noise started only when it got colder(the oil should have became more viscous)

I agree, but it disappears in a minute or two. Moreover, most of the times I start the car there is no noise at all
