Without coding yes but we are waiting to see if the coding for remembering the last ASS state will still work.

and to think I was PO'd when I picked up my 2020 X6 and found out I had to actually disable the ASS, albeit with a simple push of a button, every time i started it. My 2014 F15 could be permanently disabled with a simple push of a button that was right next to the start button. Had I ordered, waited, and paid for a MY21 and then found out I as stuck, well no one would want to see that meltdown I'm sure.

Would have been no difference since you have an M50i.

For coding, we'd have to figure out something new. Current well-known coding to enable ASS memory seems useless as there is simply no way to set ASS off even once to be remembered as such without the bloody button ;-).

Time to take a look to see in which countries ASS function itself is against some regulation ("Regulation 420, Section 100, Part XI: Engine shall not stall unless defective.") as that would give us a path to coding ASS actually off, not just ASS memory.

Doesn't Sport mode turn off ASS so wouldn't that hopefully be remembered as the last state?

No, it doesn't work that way. Sport Drive Mode/Sport Shift Mode are just ASS overrides as OFF, just like Eco is just ASS override as ON — they don't affect the memorializable ASS state.

Oh okay, I figured since Sport mode turns the light on ASS button like pushing it does it would act the same.

There's gotta be a place on the planet where intentionally stalling the engine is illegal. If there is, then there will certainly be coding for that ...

Glad I have a 2019. I despise ASS and I don't believe it actually saves any fuel. Is this the future of motoring? Sad.

Probably. Just like the totally worthless electric grill shutters/louvers. All to eek out about 1/10th of a mile per gallon. Plus, if they fail in the closed position it throws code and the engine can overheat if the shutters/louvers can't open.

When the warranties over I'm thinking about ripping out those dumb ass louvers/shutters. Mine has already failed once on the passenger side. Luckily, it failed open instead of closed!

DUMB....DUMB...DUMB design! What's even worse is it's not just BMW but almost every freaking car manufacturer on the planet has jumped on both of these band wagons! IDIOTS!!!

You can hate it or not but it works in start stop trafic.

Fuel economy will improve 3-8%. Multiple articles and tests in that. It doesn't make any sense to let an engine run idle when it is at temperature when the car is at a stop.

The system has been improved over the last years. It doesn't wear your car faster the way it is designed. It is also more intuitive and less intrusive. It never bothered my inlay last cars once I got used to it.

I wouldnt call it dum and useless.

The idea behind the shutters is good. The engine should be at working temp faster when cutting cold airflow. If the shutters are prone to disfunction it is not good off course. I have had this I'm my last 4 BMW and never saw a problem. If you had a bad experience a can understand your opinion.

One thing to keep in mind PHEVs and BEVs have no issues with ASS, since the electric motor kicks on while stopped. Pretty much all luxury brands are going with at least a mild hybrid system now, which should relieve the annoyance with the start/stop issues.

Indeed. And that is how this thread started. Because the 40i mild hybrid doesn't have the switch off possibility anymore.

I think the driving experience will be fine.

Will have to see how the mild hybrid is implemented on the 40i, does it smooth out the start/stop enough so it is unobtrusive, if so then removing the shut off switch is fine. Honestly, after having my PHEV for a month, I cannot imagine going back to a pure ICE vehicle again, unless it was something like a full M or AMG.

I am personally way more concerned about wear and tear due to the constant stopping and starting of the engine. It's going to cause more problems and reduce the life of the engine and other components.

Apparently that is not true.

The components are made stronger and coated for less resistance.

ASS only functions when the engine is at working temperature. Wear is worse with temperature difference between the components of the engine.

I think the ICE suffers more in a PHEV than the starter liter does in a car with ASS.

I could see this being more about emissions standards than absolutely minuscule MPG improvements.

They go hand and hand. There's a direct correlation between how many tons a year of CO2 your car emits and the consumption of gas.

Increased failures due to electrical and mechanical wear and tear are most likely to be observed outside the warranty period, so it doesn't seem prudent to take a manufacturer's word for it. In general, however, mechanical systems don't like anything that opposes inertia, like starting and stopping. You can certainly improve reliability, but you're always fighting against physics and, ultimately, physics will always win.

Take a spin in a M50i and you might change your mind about ICE's

I'm at about 6,500 miles and I average around 15 MPG. However almost all of my driving is short trips these days due to COVID - no highway miles.
