Is this sound the infamous rod knock?
E92 2007 N54, 130k miles. Is this sound the infamous rod knock or is it lifter? I tried purging after a long drive - hold rev at 4k for around 5 minutes. No change.

Yes, it increases repetition of the heavy loud tak-tak sound. It seems to lessen in volume after the car has been driven for a while - I barely hear it but it's there. Its loudest when the engine is cold (as in the videos) and then subsides as the engine warms up. I'll take another video when the car has been driven for a while.

Agree with the above responses. What maintenance has been done? That sound isn't low enough in the engine bay. Sounds like the front or top of the engine. It's not a clanking metallic sound I've heard before.
My car makes a similar noise on cold start. Happy owner for 7 years. FBO for 2 years. 120k miles. Best of luck man!
