Yes they do, and it works better than on the automatics, because the engine starts when you press the clutch, not when you take the foot off the brake. It's more natural and you can't really catch the car's computer unprepared. Also you can start the car seconds before driving off, by pressing the clutch, putting the car in gear and waiting. On the automatics you can't really do this.

The start-stop system for the automatic transmissions is newer tech than on the manual transmissions, maybe there are some problems not yet solved.

You can't turn it off in iDrive, but I'm pretty sure that you can change the code using the D-CAN cable and the NCSExpert software. There's a website (which I can't post here apparently) called BMW Coding dot com. The F30 is still very new, but I saw some threads on there where certain users are already tinkering around.

Of course, doing so could void your warranty, but you folks are so annoyed that you have to press a button, perhaps you don't mind reprogramming the car. Like another user said, BMW has to leave it on by default for their CAFE ratings, so I wouldn't expect this to change anytime soon.

I'm glad you posted this. I asked a salesman today how the auto start stop worked with a manual and he said " the engine comes back on when you take your foot off of the brake pedal" I thought to myself, in a manual I may not have my foot on the brake pedal, just the clutch.... what you described is much more logical and makes me feel better about the system.

I have stop start on my current 320d coupe manual and it starts up as soon as I press the clutch

You guys have a decent Lemon Law in California. If the dealer can't fix it, email them a copy...

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).

The things that car manufacturers have to do to get their C.A.F.E rating. its ridiculous and needs to be overturned. Hopefully we see some new faces in november.

The government didn't impose this auto on/off thing, BMW chose to do it.
BMW could have easily chose to not make the F30 bigger, and using the current manufacturing the weight reduction would have been even greater and the MPG even better.

I too would like to see new faces in November, but that won't change what BMW does.

[awwwyeah206]

dang this has happened to me approximately 5 times in the last month and most recently at a left turn light. You know when you think the person in front of you is going to go, you let off the brake, engine starts, but then u realize the person in front of u is an old lady, foot back on the brake and then it stalled. I have to admit I panicked a bit as I was at the intersection and it took me a few seconds to start the engine back up.

anyone bring theirs back to the dealer yet and have anything positive done?

Not really, no. It is obvious that with new models BMW wants to "grab" as many potential customers as possible from as many different market segments as possible, especially the ones that don't really care about "sportiness", and you MUST increase the overall size of the car if you want to do that, simply because of this:

Don't forget to make a report to NHTSA. If enough people will report it, there's a chance (no matter how small it is) that BMW will make necessary improvements faster or totally remove this ridiculous "band-aid" technology from future gasoline/diesel-powered models.

As I discovered when the E90 was new, until they have had time to get to know the cars, they are mostly at a loss. They don't read the TSBs and they often will do odd things to fix a problem rather than get BMW involved.

This is the price we early adopters pay.

[matt_435xi]

is this normal behavior:

I come to a stop and the engine goes in ready mode, but then if I put it in park the engine instantly shuts OFF?

I have bought new models a couple times, and that has not been the experience at my dealer. Sounds like you just have a bad dealer.

Actually, the start/stop function is a product of European regulations, not US regulations, so don't blame out politicians here for it. Further, if it doesn't work properly, that is the fault of BMW. I just took delivery of a new '12 Porsche 911 Carrera S with start/stop, and it works beautifully. You barely notice the engine turning off and on, and there is no shutter or shaking like some have described. I actually like the function, as we have a lot of long red lights here. I will be picking up my F30 in a week and a half and will be able to compare the two. However, since this does seem to be a common complaint, it seems as though BMW screwed this one up.

The crux of the problem is in the thread above. It's a dangerous problem with some new 3ers...

Yes

I agree, this system in its current form truly does sound like A.S.S. That and a few other problems that are cropping up on here make me think there are quite a few bugs in the car.

I was planning on ordering a 2013 this June, but now I'm considering ordering a 2014 next June, even though my $1500 USAA cash back will likely be gone.

[jzcrna]

Ive had it happen about 4 times. Was always when I was stopped and let up on the brake a bit. This seems to trigger the stalling from what I experienced.

Before the United States gets blamed for making the 3 series bigger because all our people are fat ( I'm 5' 11" 175 lbs. But hey , by the BMI chart I'm considered obese) , check the obesity rate for the UK. There was an article written a few months back in a British newspaper that was about car manufacturers having to make their cars bigger due to people getting bigger.Particularly in the UK. It stated that the obesity rate was climbing faster there than anywhere else in the world. People in general are getting bigger throughout the world, so PLEASE don't think I'm picking on one country or people. They simple fact is , our work and lifestyles have changed so much , even in the last 10 yrs, that most people just don't do enough physical activity anymore .

20 years ago you couldent get it up if you wernt in shape. Now they have a pill for that, so very little incentive to keep in shape for men. With their husbands getting fat, the wives feel entitled to as well.

Both my wife and I can wear the same clothes we wore in college 20 years ago because we put healthy lifestyle and exercise high on the list. No need for pills either

Perhaps, but all this checks are made before the engine is shut off. If the system did not pass each and every one of the 170 checks then the engine would have remained on.


Once the engine is turned off, these checks mean nothing. All that is left is for the engine to restart when the foot comes off the brake and the accelerator is depressed.

Thank you!! This is more marketing than anything else. Lots of things could be done to save 3 measly percent on gas.
