Were you able to figure out what this noise is?

Mine does it & it's so loud with WOT. Kinda worries me

That's 100% ASD

That's why I've disabled it in the first place. I cannot tolerate fake engine/intake noises

i go against the grain here I quite like it, the engine doesn't sound like a standard V8 because of the complex intake impulses and exhaust configuration; the sound from the woofers is at the least mildly interesting.What next from the M dept

Fit an exhaustmeister to open the flaps at all times, it sounds a lot better

Got one already came with the car and prefer the remote control for opening of the flaps. I see you bought one recently how are you getting on with it,was the fitting straight forward?

Fitting took about 10 mins and was straightforward, I like the fact that you can actually hear you have a V8 instead of it being muted.

Not sure if the Comp Pack exhaust is different to a non-Comp Pack car but it sounds good

Think the CP exhaust is a tad more rorty so I have read.
On a side note how is your brake disc swap going.

New discs and pads fitted at a very reduced rate by BMW as a gesture

Once they are run you'll get that sharp response from them that new M's have.

2015 one and it does it, only when I give it a proper bootful but I love it.

I suggest you give it a shot and drive the car at least 500 miles without ASD. You'll fall in love. You'll be able to hear different sounds from the engine.

I can always disconnect it in the boot and give it a try, maybe I will.

This was 100% NOT ASD. I had the noise with it unplugged, coded out, everything.

Never found out what it was the car was totaled a week after that video

Was definitely a mechanical issue that was starting

ask me when u want to know how to open those puppies up (hint: nobody on here or youtube tells u the right way.. it doesnt involve hinged ratchet adapters nor any adapter to get the torx screws unscrewed)

Thank you for the info, mine whines when it is cold out when I rev it just slightly on a cold start. Sounds like an old Chevy power steering with low fluid.

I don’t have the whine like in the video in 3rd gear high speed though.

It isn’t a horrible whine but not what you would expect from a bmw.

I’ll check out the tensioner.
