This was exactly what I experienced when I drove my 320i yesterday in ambient temperatures of 29° to 32° F (-1.7° to 0° C). Once the engine reached operating temperature and I shut off the seat heater, auto start stop worked like a champ.

How are people feeling about AS/S now that some time has gone by?

I find it funny people say this, but when I want to use cruise control without stability control, I get "why would you want to do that" or "that sounds incredibly dangerous/foolish/dumb".

BMW does not allow the owner of their own car to make the choice for themselves.
These cars are very nice BUT all the garbage we have to go through is making me wonder about my purchase for my next car.
Having functions is a really good thing IF I should choose to use them, this should be my choice to we I don't have to be inconvenienced and controlled the way we are with these very expensive vehicles.

I hate having to turn the DSC/DTC half off every time I want to drive a BMW around a corner. why can't the car start with it off?

I don't have my car yet, so can't comment yet (Im guessing I'd hate it), but you can't possibly be comparing your examples to braking at a stop sign/light and having your engine shut off. Apples to oranges.

Why do you have to turn part of the stability control off when cornering? Unless the road is icy, I've never had the nannies interfere. If you are driving hard enough to lose traction in a corner other than from a bump or ice, you are driving too hard on the street.

I really don't like the ASS feature; actually, more to the point, I really don't like that ASS is turned on by default every time I start the car and every time I switch to EcoPro mode. The next time I take the car to the dealer I'm going to have them reprogram the ASS function so that it remembers the last setting.

That sounds like opinion, not fact. seriously - it happens even when going straight, it can be annoying. it interrupts power delivery for a full second or two, which causes problems in the winter, the rain, etc. I assume it's due in part to the car having an open diff and bmw not wanting to apply the brakes all the time. if you want to power out of a corner, it happens frequently. feels like it happens at about 5% slip.

and BTW, DTC light on = more slip allowed, not more yaw. at least according to what I've read, and experience with ice racing confirms it. car will clamp down on any yaw, even with DTC on. gotta turn it all the way off for fun time on the ice. it's worth 5-10s per lap.

So wait, ASS is still always on every time you start the car? That's terrible, I thought I read in the first page that there was going to be an update so that it remembered the last setting. Can someone confirm the situation so I can get this taken care of when I pick up my car?

I never have to turn off ASS. It's off always on my 2014 328i.

I have a '14 335 GT and the last ASS setting is remembered when in Comfort Mode. If I shut off the ASS while driving, then turn off the engine, that is the setting the car starts up in. I thought I was imagining things at first, but then I started paying attention and, sure enough, the ASS stays deactivated if it is off when I turn off the engine. It does not do this in Eco Mode, however. Don't know about Sport Mode.

I'm ambivalent about ASS. Frankly, I could do without it.

I don't know if this is mentioned elsewhere, but something I found out purely by accident is, if you are at a stop with the engine off you can restart it by twisting the steering wheel. I was playing around one day and giving the steering wheel a slight twist and, lo and behold, the engine started! I thought that was pretty neat.

Yes, there is an update and a TSB to go with it. My car has not had the update applied to it yet (I guess the previous owner just lived with it).

I'm sorry, I guess I wasn't clear. If ASS is deactivated when I shut off the engine, then it is not active when I start the engine later. If ASS is activated when I shut off the engine, then it is not active when I start the engine later. The last setting is remembered.

I like it. In my opinion its much better integrated in 6MT cars than automatics, since it can be controlled with the clutch.

Its been very cold around here, and I'm finding myself disappointed when the engine continues to run because of the cold. I kinda like the quiet/still feeling with the engine off when stopped

My "d" remembers the last setting so I don't see it as a problem.However,those whose models default to "on" have a legitimate gripe IMO.About 95% of my miles are Interstate miles so I have no use for it anyway.Things haven't gotten *so* bad for me that I have to put up with the annoyance just to save a few pennies on gas (diesel actually).

I'm keeping my car a while and I don't wish to prematurely wear out its engine or transmission for paltry/phantom savings. I tried ASS when I first got the car and didn't consider it refined either. Perhaps it's the most useless feature BMW offers IMO.

I feel like I would be OK with having this system so long as I can effectively set a preference for it (have it stay off/on on restart after sleep mode). The manual mode (in neutral, clutch not depressed) option sounds quite tolerable to me.

one of my favorite features in my N52 530 was the "heat at rest". I could pull in and wait for people with the heat on in the winter without leaving the engine going. it's a pity the N62 has a belt driven water pump, if you ask me. I spent far too long trying to find where they relocated the button to until I realized the car had a belt driven water pump.

The type of ENGINE water pump has nothing to do with Rest Heat. Cars that offer that feature have a small auxiliary electric pump in the heater circuit. The feature was probably cut as a cost-savings measure.

In the newer cars (2014+) it remembers your last setting.

The N52 had the feature because the engine had an electric water pump - the N62 does not. if you look at the engine as a whole, it does matter. if you look at it from the "any engine could have an electric water pump" point of view then you are correct. however that's not quite in tune with reality. I don't think they were too concerned with saving money on the $80k-ish 550i, rather that as a revision of the N62B44, they simply didn't bother to redesign the cooling system that completely.

How to enable auto start/stop while driving an auto (manumatic) in manual

I have a 2015 F34 with automatic transmission, which I love to drive in manual mode. However, I also love the auto start stop feature when drving the auto mode (only available when driving in comfort mode). It does not bother me a bit. I like the fact that my car is resting at the stop lights.

The start/stop feature is disabled when I move to manual shifting. Is there a way to enable start/stop while remaining in manual mode at stop lights? The way I currently do it is, I shift to auto drive-D when approaching a stop light, but this is cumbersome. Also, I would like to put the car to sport mode, and then to manual shifting, and then still be able to have auto start stop. I have the dynamic handling package, which adjusts chassis as per driving modes, and I like the sport mode chassis for better road feel.

Am I asking for too much? (I could still be quite fast off of stop lights even with auto start stop. Given that most of the time I am going to be limited by cars in front of me.)

Again, the type of engine water pump has no bearing on the matter. For instance, my 335d has a belt-driven pump, but European models had Rest heat - due to the auxiliary pump.

You have to add the hoses and pump; not as easy as just coding. The link I posted was to the European car; the US car doesn't have the pump and hoses.
