So much regret doing the OTA update, can no longer disable ASS. Is it only the G05 that cant be disabled? Seems like there are no issues disabling it on the 5 series.

With full awareness that my comment may dtrir up some dust or irritate some ppl; let me ask why do you want it disabled?

I am genuinely amazed how well implemented a-s-s is in the current G05 - a vast improvement over my prior car (2021 G11 7 series), and light years ahead of what I had in my 2015 F10 5 series

In the current car I hardly notice the engine kicking back to life, I don’t experience any body shudder or any annoying noises (all of which were the downsides of a-s-s implementations in the prior cars). Zero reasons to complain, and in fact just some reasons to appreciate this gadget as it seriously improves fuel efficiency (80-90% of my mileage is city driving)

I can feel it, and me no likely. If it works for you great, doesn't work for me. Fortunately, I'm in the M, and I'm always on M1 or M2, problem solved.

I just dont like it, no matter how well it works i still feel it especially when your AC slows down when you at the lights when its 100+ outside.

I didn’t notice the a/c to work any differently when the a-s-s cuts out the engine… but, I get your point. To each their own

[jad03060]

The a/c on the PHEV is an electric compressor…so, it works just fine when the ICE is running or not! But, I think you’ll find more and more companies on more and more vehicles that will be disabling the ASS, as it affects their corporate average fuel economy, which keeps being mandated to improve. This is also driving them to improve the performance of that functionality. Some have a very long ways to go in that department, but the newest BMWs are pretty good compared to some others.

No, it's not just the G05, 03/2023.xx killed ASS disable on my G20 330ix too.

They are not under any regulatory requirements in the US with regard to ASS other than the car default to the mode or condition in which it was tested at each startup. That mode/condition includes start/stop if it was used during testing. So used during testing = must default to on at each startup.

The testing is done on a dyno, and the way the loop is set up, ASS helps generate better numbers. Those numbers don't translate very well in the real world where its benefit is often marginal, but it's effective on the dyno, and those are the numbers that matter to the manufacturer.

Realistically, they could have left ASS and some other tidbits they will never monetize, out of the walled garden. They would remain in compliance and customers could have what they want.

Off-cycle credits are a big reason that have ASS and not allow it to be turned off by the customer. Maybe moreso than the mileage testing.

[crabman]

It's not a regulatory requirement, which is what I was talking about.

In any event the off-cycle crediting program is used to identify and define technologies that deliver real-world benefits but are not adequately demonstrated on the official test cycle, it's why they're called off-cycle credits. ASS is considered fully demonstrated during the test cycle if it is used, and can't generate off-cycle credits.

No, that is not correct. Idle start-stop is used for off-cycle credits.

Ah, your right, I had to go look it up, but they did change it in revision. Thanks for the heads up!

I can disable this annoying thing in my '18 G30, which I always do. I cannot see how this can be good for the starter. Off/on/off/on in city.Wouldn't it be a lot of wear and tear? I'm thinking of moving to a G05 but I'm not sure there's any "tricky" way to disable the ASS.

No ill effects at all, the system is designed for start/stop usage.

Agree that it has improved a lot since it's introduction! But still not yet perfected.
If the store has a feature to purchase, i would definitely jump on it right away without hesitation.

I can still program AS/S on my G05 with 07.23 software thankfully. Must be a US thing.

Either by putting it in sport mode or disabling traction control will bypass the ASS. It's what we do.

The only time it uses the starter is during cold starts. After the engine is warm it uses the hybrid system to start the engine. So as far as the main starter goes it should be okay from wear and tear if that's what you were concerned with. This is at least what I've read.

My 2017 G30 remembers the last left position - so I don’t have to turn it off every time I get in the car!
Think it was the only year that did it - odd for sure but I’m thankful.

So it is a myth that ASS will wear battery and alternator down quickly? Thats the only thing yhing I am concerned about although compared to my other cars and last X3, 2024 X5 ASS is not that intrusive. Hopefully that is a fact as I plan to keep this car long term.

Yes, completely untrue. The systems are designed to work that way. Do you worry about opening and closing your doors too often? Likely not as they are expected to last.
