I was driving my car today in sport mode it was still doing it in sport mode when downshifting. I have a 2021 M5 Comp. Guess we'll see what happens when it goes back in for the break in service.

No change after the update. Maybe this is all to do about nothing.

Been trying to stay quiet on this point given the earlier dismissive comments bc I have MPE...

...but I also think there's a good chance this is much ado about people getting confused about the Sport + button vs. the exhaust button and how they are sort-of linked by default settings. They can also be de-linked manually to increase or reduce crackles-N-pops in all "engine" modes should you choose to do so deliberately.

M5's don't pop and bang in sport engine. Are you referring to the overrun sound you get after lifting off from an acceleration? Those you get in every mode but pops and bangs only in sport plus engine.

I think we all just need a North American LCI 2021 owner to post a video of them revving their car in sport plus engine/doing a few high rpm upshifts and downshifts for comparison.

In theory the OBD tank valve recall could be done in isolation without any iDrive update re-configuring the ECU. However, it appears that BMW is silently applying the updates and may do so even when the car is in for this recall bulletin.

I manage a large fleet of vehicles for my company.

I recently get one of the staff a new 1 series.

I notice this 1 series has the "A" button on the side of the indicator stalk.

I think to myself "I did not spec this driver high beam assist or adaptive headlights. Why does this car have this button?"

Turns out BMW now install the hardware from the factory for certain things (this being one of them) but do not activate it unless you pay a subscription.

I can see this from two angles. The first being it simplifies BMW's manufacturing line with the goal being to lower the overall COGS. The second being as with that in place they have the "upsell" of software enabled features no differently then "in app" feature purchases that are prevalent throughout the digital world.

This video makes it seem the stationary burbles are still there:

In a week-ish I should be taking delivery of a 2021 M5 Comp without MPE, so just the m-sport exhaust, and can post a video if the question still looms.

Ok this LCI M5 sounds exactly as it should at least stationary revving, no different from pre-LCI north american M5s. Assuming the M5 in the video has the software update? that would be good news. Would have to see how to exhaust sounds when driving.

I don't think anymore that has had the software update done will tell you that the burbles/pops/bangs or backfire is gone. It's reduced in volume and frequency on downshifts. The answer to the subject question is, NO. However, there is definitely a change to the exhaust tone. Only noticeable to those that drove the vehicle before for a while.

I have been looking at the new Cayman GTS 4.0 and perhaps this BMW BS will help me decide.

My dad had a V10 M5 when I first got my 2003 RS6. His car sounded like a Honda Civic, while my RS6 has a naturally made ROAR that BMW can only dream of in their turbo cars. I don't know how Audi does it, but with Audi's Sound Enhanced Exhaust the RS6 sounded GREAT when you got on it, but was quiet for a daily drive. The addition of the FAKE noise is complete BULLSHIT anyway. They should have been able to do it o'natural.

So, here is a consideration: When I got my 2016 M2, I quickly coded out the fake noise because that car was obnoxious when driving down the highway. I did the same on the M5 a week after I got it, not realizing the BUTTON did the same thing. After a big service (ie. rebuild the car) I noticed the first day I drove it, wow this car is louder than I remembered. Then I release they coded it back to stock. I pushed the button and said um. that is easier.

So....long story short, has anyone look with coding software to see if they can TURN THAT BACK ON THEMSELVES????

yes you can easily do it by restoring a backup.

I can't comment on the car's pops and bangs when it's being driven, but if you look at that blue LCI M5 video above, (assuming it has the software update) the stationary revs sound exactly the same as the "normal" pre-LCI pre-software etc. M5s. The frequency and volume of the pops in neutral are identical.

The most noticeable difference to me was while driving. I don't rev in neutral enough to notice that difference.

I see. Think it's safe to say that I won't I won't be updating my software anytime soon.

State Inspection done. Not at BMW LOL. No issues. NO "recall" warnings, Nothing.

Stay away from BMW Dealer unless you just go in. Do you own oil changes.

I took my M8 in for the recall issue and they updated the software to 11/2020.36.

Here is what I was left with after, sounds nothing like the M5 in the video but it did last week .

Wait a minute, I thought EU M8's were neutered from the beginning due to all the EU emissions and sound regulations? Last I recall, all EU M8's didn't have a burble tune (and hence no pops and bangs) and sounded neutered since the beginning?

No, my M8 definitely had the pops and bangs last week before I took it in, especially in sport/sport plus modes.

Previous to that I had a 2019 M5 which was more defined, also a late 201 M850. Both of these were far louder but my M8 still had them before this update.

Seem they have been reduced here in stages, this last update has taken it away completely.

Are you going back to question them on this ?. If you bought the car for its character, and exhaust note, then BMW have taken that away from you, i certainly wouldnt be happy.

You'd only be able to notice the difference if you had an M5C before the change. Mine is in the shop now and they're working with BMW tech support to see if they can revert to the previous software version. I'm not holding my breath.

Hopefully, it works out. I'm will ensure they don't update any software and just do the service/look-see when the next service is due. I'm not subject to state inspections in Michigan but stationed in NOVA.

ashmostro Maybe we all should get together and do a sound off.. LCI, CP pre, and post software.

I don't have the SW update thankfully, but am wondering, after seeing the latest CarWow vid of a new X6M where it had the same restricted revving as we see with the new Porsches etc
Neither my 19 M5C nor 20 X5M have any issues with revving freely to the limit.
The 19 M5C has all burbles, crackles and pops, the 20 X5M not (at all) only the upshift burps from time to time. But both freely rev without being capped. Wondering if this new update limits the free revs as muffling the exhaust?

Also for those noticing some improvement in drive... improved launches?
