I had this a few months back and it got less noisy once warmed up. Got home switched off then cooled down a little then restarted and it was gone and have not had it since.
I'm thinking maybe intake shutter valve or some other valve stuck in an inbetween position causing air turbulence and then freed itself back up. Hard to say if it is exactly the same noise as would probably sound different in person but would go up in pitch when revved same as in your vid and was barely noticeable above 2000 revs. Also it drove fine with noise there. Mines manual not an auto, is yours still doing it?
Thanks for the reply. Yes unfortunately still doing it. It only started yesterday, when the Mrs drove it home from work. The car drives fine and pulls as usual. The noise seems to only be there between 1k-2k revs whilst driving slowish or stationary. Unless I just can’t hear it when driving faster.
I thought it may have been turbo related with the noise I am hearing. Hoping someone like @F6HAD with his expertise, may be able to shed some light on the issue.
Well not sure what has happened, but I took the car for a drive yesterday after replacing driveshafts on both sides, and the noise seems to have disappeared?! Also the shaking/juddering has now been completely eliminated thankfully
Nothing came out whilst changing the driveshafts. And I’m a bit OCD with checking the ATF level regularly, and do a drain/fill every 15k (yearly) to keep the fluid fresh. So I’m not sure really what was causing it.
