E63s knocking
I want to buy this e63s from auction. It has 80k miles its a run and drive has a check engine light. The concern is that on the idle video can hear this knocking sound in the background. Im aware of the purge system tick but this seems different. I was thinking maybe hpfp since it missed a couple of beats(maybe rules out rod knock) or maybe timing chain. But it does seem kind of metallic.I would have to buy the car sight unseen. Does anyone else have a better idea? Thank you

The engine idle sounds rather smooth as presented.
The good news is the unusual rattle is not in sync with crank Rpm.
This 80kMi car could be a good/bad deal...
who knows about everything else, may need its $20k engine out repair soon - Your call!
