To specify, I don't want it coded OUT, I just want it coded so that it's not automatically on when I turn the car on. I use it when I'm in traffic, but I would like the option to manually activate it, like the Lane Assist. Is it possible to code it so it's not automatically on when I turn the M2 on?

I'm curious: what's the reason to ever have it off?

I don't really want it off. I was just experimenting and not sure if I'm noticing a difference in mileage/coasting with it off. I forget to turn the feature off when I get in the car to get a true answer so I was just curious if there was a way to code it so it would remember the last setting.

As for why you would want it off, I'm sure most of us learned to drive in a car that doesn't have it (it's my first car that has it), so I'm pretty sure there would be times we would want to turn it off, just like there are times we want to turn the Traction Control or Dynamic Stability Control off.

It's a great feature and I know that it works well, but I was just thinking outside the box.

When you are on the track you definitely want to turn it off.

That's fair, but it sounds like op is thinking about doing it in normal traffic.

Track aside (which I hadn't thought of) there's no reason to turn it off ever IMHO. It doesn't do anything unless you're actively about to have a collision, which can happen to anyone with one little mistake. It's not the same as traction control which you can make arguments for because it DOES change how the car behaves even in some cases where you are still in control (though I cannot think of a single reasonable excuse to turn it off completely past what you get with sport+, unless you're doing donuts it's not going to interfere and you shouldn't be pulling that shit on public roads, but I'm getting off topic).

Anyhow, not my car not my business to tell anyone else how to drive theirs really, just sharing my thoughts.

I’d never ever turn it off

Saved me from hitting a deer 🦌 at 40mph and without it I definitely was going to hit the quick sucker and then I was given a huge helping hand

Amazing when it actually saves you

I put this up on the Forum for two reasons:

First, because it is something I would like to know: if it's possible to code it the way I am referring to, but again, this is more just for my scientific curiosity because if it absolutely shows no benefit to being off, then I never would disable it.

Second, because this is the place where we are able to voice our opinions and thoughts, that's what a Forum is for and I welcome all feedback. I have no problem with you expressing your opinion as long as you are not attacking my opinion, and you are not doing that. So anything you have to say would be greatly appreciated because this is how discussions happen and we learn to be more open minded to other points of view. Sometimes, we just need to see things from a different angle...

Cheers mate, I appreciate you being open to contrary opinions.

I'm a software engineer, and while I know fuck all about bmw sw (just acknowledging I know I don't have special knowledge here) I really can't imagine it would have an impact on mileage fwiw.

But hey, I appreciate the curious mind, and there's no harm that I know of in trying it out to verify! Maybe there's some crazy ass thing the system is doing that doesn't make sense to anyone but a bmw engineer lol.

I don't think I have much else to offer on this topic so I'll just quietly lurk until some answers creep up. I'm not into the coding scene. Good luck with your pursuits!

You may be interested to know that I actually spoke with a BMW Tech not too long ago, and he said that theoretically, the system should never affect the braking or coasting UNLESS it senses something with the Imminent Collision Radar. That is how it's designed and that makes perfect sense to me. I think that what I saw/experienced was just a fluke with specific conditions (weather, road conditions, etc...) but the main question still remained so now it's more of a coding question as you pointed out.

That is indeed interesting. Thanks for sharing.

Track use. Forgetting to turn it off can fuck up your day

Yeah someone else pointed out that oversight. Haven't been able to do anything like that with mine yet and never had a car with these features before so it didn't occur to me!

Do our cars have automatic braking?

I have owned my car for almost 5 years now, and the car has never braked on me once. Just an annoying chime kicks in with a warning sign. I highly doubt we have automatic collision braking??

I believe it does, actually, but not until the absolute last second. Less of a "avoid the accident" feature, more of a "lessen the impact" feature.

I could be wrong though.

Wait, F87's have radar? Where exactly is the sensor? It's not that huge thing mounted below the grille that G-series cars use. It's not embedded in the BMW logo on the hood, as it is on my VW logo on my Golf R.

I think the collision warning system only uses the camera located behind the rear view mirror. Can any one confirm whether this is the case, or if in fact a radar sensor is lurking somewhere, and if so, where?

I've had it lightly and medium tap the brakes, but never been close enough for it to do anything more.

For reference.

The warning time can be set.

Via iDrive:

1. "My Vehicle"
2. "Vehicle settings"
3. "Intelligent Safety"
4. "Warning time"
5. Select the desired setting.

The selected time is stored for the driver profile currently used.

Thanks BigKutta

Oh nice tip I'll have to check that out.

From my understanding, our M2s only use the KAFAS camera behind the rear view mirror for the collision warning system; we do not have an additional sensor behind the grill or in the bumper.

Because it does more bad than good if you are a good driver , you might have to manuever out of a nasty situation and the sensor would apply the brakes for you when you DONT WANT the brakes to be applied

[3t3p]

Mine is sometime tetchy. If going round a corner and it's raining it thinks I'm about to drive into parked cars.

As above is it an actual active braking system?
