Can anyone give me an idea if the bottom end was failing in anyway, if it would throw an error code and cause noticeable difference in performance?

As some may have read, I've got a knock/rattle/ticking which is prominent from the inside of the car and can't be heard outside.

Desperate to know what it is

 

Might be worth posting a vid of the noise.

 

I've recorded the noise, but the trouble is it sounds much worse than it actually is, it's literally all you can here through the iPhone, if that makes sense, and it sounds worse than it is.

Plus, I've no idea how to post on here since I can't use tapatalk for some reason?

 

Bottom end rattles are usually diagnosed as the sound is inconsistent as the bearing spins.
