G29 Exhaust Soundtrack

Hello,

I'm new here, thanks for letting me join.

My G29 20i exhaust doesn't sound the best... Every other 20i I've heard sounds amazing with pop and crackles, unfortunately I don't get any... Pretty much every review online regarding the 20i mentions a lovely soundtrack. My Z4 just isn't doing this :(

I'm driving in sports+ with the gear selector in M/S mode, but still nothing.

My question is, has anyone else had this issue? And does anyone have any advice?

Thank you :)

George
 
That’s because you’ve purchased the wrong car and should have got an M40i :fuelfire:
Just kidding.

Odd that it should sound quite so quiet. Can’t say I’ve read or heard about this online.
Is it worth speaking to your dealer about it and ask if they can check it over.

Hopefully someone with a 20i will be along shortly to provide some further info.

Welcome to the forum by the way!
 
Welcome to the Forum..

That's odd, my 20i has a pleasant burble and pops a bit when changing down through the gears.

More noticeable with the top down but that hasn't happened much lately! :)
 
Thank you both for your responses. I think I'll be taking a trip to the dealership, hopefully they can figure it out :)

My top hasn't been down recently either, bring on the warmer weather 8)

its mostly in the low rpms that it does it for my M40i, so i guess you may get more sound out of it in comfort or sport plus but without the m/s mode.
 
Maybe there is a fault with your ASD active sound design box that generates a lot of your exhaust notes?

Does the 20i have ASD? I thought it was only the 40i?
 
I can't find anything in idrive for ASD settings, even an on/off. Wouldn’t say my 30i sounds particularly good.

It’s definitely an option in Carly, just not sure what models

Edit: doesn’t say it’s model specific

Can't find anything in Bimmercode either mate.

Never used, or even seen bimmercode, so don’t know if the process is the same for all cars

Cheers Andy, found it and turned off.

I must be in the minority as I don’t mind it.

I'll try it with it off, in the video Andy linked the presenter shared a sound clip and pointed out you can hear the gear changes. That would suit me, hate why gear position isn't displayed in all circumstances.
 
As far as I know, as of 06.2020, almost all sports models got an update on the ecu, which deleted or significantly reduced burbles/crackles map. (As of 06.2019, they also added OPF in the exhaust system. We all have it, front half of our mid silencer is OPF)

My Z4 30i is build 11.2019, so I can hear some crackling sounds sometimes. I don’t know when does exhaust flap open, but I think I hear them in sports mode.

I have seen a 2021 model 30i, who also installed an M performance exhaust (of some other model, there is no specific for Z’s), who is not satisfied with the sound…

I have plans, either deleting the mid silencer&opf, or leaving it as it is and making a custom rear silencer or converting&installing a motorcycle Akrapovic exhaust to the end with right/left tips. (My only concern is keeping or removing the electronic flap actuator.)

Or, I might keep everything stock, and my tuner can increase the duration & aggresiveness of the existing burble map, with a soft performance tune.
 
I have a 30i build date February 2020, I some times get an odd crackle, I think like someone else said its on the lower revs, only really hear it with the roof down. Ive used bimmerlink to have the exhaust flaps open all the time, definitely sounds better with them open. Ive also turned the fake sound off, but I found with the roof on the car is just too quite, looses a bit of the sensation of speed, so I turned it back on
