Warranty void, not likely.

Unless specifically stated in your warranty manual, this is not likely to happen. Turning off a system that can be turned off is not a "mod" per se.
I'm not saying that your warranty -will- be voided, I'm just saying that in the past any modifications using the D-CAN cable and NCS Expert software have been frowned upon since you have the ability to severely damage your vehicle if you don't know what you're doing.

We actually had a roundabout installed in our area recently. It really relieves pressure during rush hour at this intersection without the need for a traffic light that would back things up the rest of the time. I wonder if this experiment will lead to more instances.
Yes, it relieves pressure during the day. Then within 2 Years some bloke and his poor family will get wiped out at night and then the lights go up again. Then 10 years later the board gets the idea they can improve traffic flow by taking the lights down and improving the roundabout. Then within 2 years later, some bloke and his poor family gets wiped out at night and then the lights go back, and so it repeats indefinitely.

If the front wheels are turned more than [x] degrees, AO won't engage. (I couldn't remember the number.)

If there is too much load on the engine (i.e., AC is at max), AO won't engage.

There were roughly 10-15 circumstances where AO wouldn't activate even if it was left "on".

I don't remember all of them, but there's probably something written more about these exceptions on one of BMW's websites.
Here is the list i have posted numerous times

Stop Start wont engage if :

a) Outside temperature is below 37F (3C)
b) Outside temperature is above 95F (35C)
c) Car interior has not yet cooled or warmd up
d) Engine not yet warmed up (does not have to reach full operating temp)
e) Battery charge low
f) Directly after car was driven in reverse
g) Stering wheel is turned after car has stoped
h) Stop and Go traffic
i) Gear selector in Sport or Manual
j) ABS was activated before stopping
k) Windshield is fogging up
Okay, is anyone willing to jam one of the sensors? For example, what if take some translucent tape - a small piece, and place it over whatever sensor is used to determine there is mist on the windshield?

Next, you would have to disable the auto button on the driver's air condition since auto mode attempts to react and clear the mist.

This way, if the system always thought there was mist on the windshield then it will never enable start stop?

I have no idea if a tiny piece of tape would work over the mist sensor, but you get the idea...just fool one of the minor sensors that has no affect on other systems.

Or just use 2 fingers to start the car
One pressing the start button and the other the stop/start deactivation button right next to it

I am with you. But, so many complain.

There is an element of government intrusion that would make it a tiny victory if we defeat the default auto start stop.

Call me a rebel.

Actually, roundabouts are becoming more common here in the states. Now if only we could teach drivers how to get through them without crashing.

We have 2 types (large outside residential areas and Small inside residential areas)
Each has it own rules ( Give way to the right on the large ones and operate like 4 way stop on the small)

But do you think anyone can get it right ? No

Because several people have experienced a problem with it. Their engines are sometimes not turning back on. It happened three times while the Motor Trend editors were testing their car. And other forum readers have experienced the same thing.

This. And the fact that it hardly saves any gas.

The figures I've read say 5% savings. That's a lot. If you drive in stop and go traffic, think about how much time you are stopped with the engine running. It's a lot. Total waste of gas.

Its main purpose is not to save gas, but lower emissions.
Emissions regulations are driving most of these technologies.

Remember, you can start the engine on automatics by pressing the brake harder for a moment. This will let you get the engine started well before you move the foot off the brake to give some gas. I tried this on a 328i.

You are also supposed to be able to stop it from turning off when you stop by doing the same procedure right after stopping but I haven't managed. Both these things are described in the manual (Swedish at least).

I need to understand this system better.

Ok, after you come to a stop, how long until the engine shuts off when the system is on?

If I come to a stop sign in my neighborhood, I approach, brake, stop. I saw there was no one there as I approached, so I just want to make a complete stop, wheels not moving, and I want to take off quickly. Will the engine shut off once the wheels stop moving, or is there a time frame until the engine shuts off?

I'm wondering because I can see a whole set of scenarios where the engine shutting on and off during stop and go would simply be annoying.

So, I decide to shut it off on EVERY start up. Ok. But then, in what driving scenario would I then chose to leave it on?
And since there is a choice to be made anyway, why have the default set to ON?
Auto on/off is not a mandatory tech, not yet anyway, by the EPA.
So, why not have the default at OFF?

Anyone know if that auto on/off has it's own fuse?

When I tested the auto stop/start, I noticed the engine turn off after an absolute-complete stop. I don't know about your driving habits, but I rarely come to an absolute-complete stop unless I'm at a red light or a stop sign (mostly ). If you haven't test driven the car yet, I encourage you to try it out. When I test drove it, I didn't find the auto stop/start too annoying. My wife couldn't get the auto stop/start to actually work. Hahaha. I guess she never stops.

If it was really annoying, I would find it less stressful to just push the "off" button instead of trying to fake it out with hard braking or turning the wheel or other cheats.

It will be mandatory on all European manufacturers soon, thats why most have brought out such a system. Porsche, BMW, Ferrari, VW ect ect, Japanese manufacturers are also rolling it out.

This is also BMW's 2nd Generation system. the 1st was on other euro BMW's for many years.

With a manual gearbox it will shut off when you are at a complete stop, have put the car in neutral and released the clutch.


With a Automatic if you slow down and keep you foot on the brake it will stop the engine about 2 seconds after you stop completely.

If after you stop you briefly press the brake pedal a bit harder or release it slightly the engine will not stop.

lol I don't have it yet, it's somewhere between England and Panama on a boat, coming my way

However, when I placed my order, they pulled a 535 series off of the shelves (kind of looks like that, seeing how they literally stack their stock here) that had Mojave with beige to show me how it looked. And, yeah, I feel it's an awesome color indeed, it's much better than most people think it is

Here are some pics I took of the color up close (I made them just to get a feel of the color up close, so you wont see the whole car):

I believe Motor Trend reported annoying bucking and such in their 335 tests with start/stop, while the 328 was fine with it.

which is funny because some other publications said the opposite.

It's a somewhat annoying technology that we are going to see on more and more cars.

Oh, I see. That sucks.
Ok, at some point we'll all just have to learn to live with it.

This is going to suck if you have a dead battery.
Consider that now if your battery is dead, you can get a jump start.
Great, it's running. But, you're going to need some miles before you can even get some juice into your bad batter.
You get a jump, drive off and as soon as you get to the first stop, the engine dies. Great. Now you're blocking traffic while waiting for road side assistance.

But, how about a compromise.
They could at least give us a stopped time setting.
Let's say we can set if for 5 or 10 seconds after stopping.
That way we can come to full short stops at stop signs without needing to restart the engine.
That would be useful, cause if I'm actually stopping for a long enough period to get value from shutting off the engine, then shut if off instead of a 2 count, which is about the time one would wait at a stop sign.
I'd be cool with that.

Yeah, I do need to get a test drive. Maybe it's not as bad as I am picturing it to be.
And, at least I can shut if off at start up. I'll just have to add another button push to the start routine.

BTW, any word on a fuse for the auto on/off annoya....I mean "feature".
