So I'm looking to get me a 318 with the infamous n42 engine :) ,

it has chain rattle, that should be sorted out with the new updated tensioner.

But when the vanos kicks in, it starts to knock and sound like a Diesel engine.
What's your thoughts on that?

Check my video , after 30sec mark it begins to knock ,,

How i know that this sound is from Vanos is because of this second video,
A mechanic enables/disables the vanos, to force the sound.

whats the fix on this?
