Rattle(s) driving me crazy- need help!
Hi all great forum- I have spend hours reading threads on here both before and since getting my car (2015 V6S coupe AWD storm grey)
However I'm now having problems with a rattle from under the bonnet which is driving me crazy. I took the car for its last warranty service and reported this problem but a combination of it's intermittent and they weren't really able to replicate plus there is an aftermarket exhaust which they blamed meant it wasn't fixed....
so looks like I have to try and work this out myself... here's the clues. if anyone can help me solve this theres my gratitude and booze in it for you!:
1. quite high pitched metallic rattly noise intermittently
2. from under the bonnet but seems quite close to dash
3. occasionally when i go over bumps or uneven road i hear a rattle which sounds like the same thing. sounds like a metal rod or coat hanger rattling against metal.
4. when it really gets going it's most noticeable at IDLE when it sounds like a fluttering spinning rattle, like something driven off the cam. this happens in gear and in neutral or park and can get loud- it's intermittent but happens most drive over half and hour -- everyone who's been in the car comments on it (except of course the service guy when it didn't happen..)
5. weirdly, when its really rattling at idle, it will usually go away if i turn the steering wheel???
This is really killing me- i don't care if parts have to be replaced... I'm thinking: tensioner? aircon (happens with this off though)? ?supercharger? something with the steering??
Any help would be so gratefully received.

(ps- there's another buzz thats a problem but maybe leave that for another post...)

A strange one for sure.
Lots of those symptoms sound like it's the classic torsion isolator/coupler rattle, but others suggest otherwise (close to dash, going over bumps, goes away with turning the steering wheel none of which make any sense if it was the coupler).
Sounds more like a loose exhaust heat shield, in the central tunnel just after the cats/downpipes.
Get it up on a hoist and poke around in that area.

Here are a few I found "Supercharger coupler" is the one I thought sounded familiar

Here's the TSB for the supercharger issue, but it only applies to the V8. Don't recall if anyone's had this issue with a V6...

Nup, also applies to the TVS1320 (??) on the V6, I had the snout/coupler replaced on mine under warranty about 18 months ago and there is a separate TSB for the V6, JTB00356NAS1 attached below (although there could by now be a later version).
I posted about it on another thread somewhere and commented that I couldn't really detect much if any change in the rattle after the "fix".

Too low-rez to be legible, unfortunately. However, Google pointed me to another forum where you posted legible images.
