I have no idea what exactly this is, no codes being thrown. Just this god damn rattle. 12-15 is when you can hear it the best.

Thank you. That's odd though because I haven't done any work on the engine recently that would cause something to be lose and it's hard to believe something loosened itself but who knows

It only happens at idle or it's inaudible at driving RPMS

I have a smiliar sound but mines not as loud. From what I have read it's a bushing on the driveshaft called giubo bushing. Well I'm taking my car in to the shop to get it inspected.

I've heard of that part!

I just got back from a shop and they suspect it could be the timing chain rattling either that or the vanos motor but I didn't think that made a rattle. Probably going to have to take it in for a more in depth check.

giubo or driveshaft flex disc.


Anyways, you will have unnecessary drive line vibrations if you giubo is cracked or ripping. Easy to tell under the car with the plastic guards off.

It's not guibo/flex disk - simply because guibo/flex disk doesn't move when on idle. It's something else - looks like sound is coming from under the hood/engine. If OP can take a better video with the hood open - so we can at least pinpoint where is sound coming from
