When they pushed out 11.23, I thought surely it would work, yet here I am again, waiting for the car to tell me when it is ready to begin the install - parked, e-brake on, etc.

What I have ----->The Schumacher SC1282 is a 10-amp, 12-volt battery charger and maintainer that can be used on automotive, marine, and power sport batteries. It has a microprocessor that automatically adjusts the amperage rate, and features multi-stage charging to help extend battery life. It also has LED light indicators and simple button controls for easy use, and reverse hook-up protection to prevent the charger from operating if the clamps are reversed. It is compatible with standard, AGM, and gel batteries.

When you guys talk about charging the vehicle, are you referring to e cars with lithium batteries?

I have a X5-30D with the software update stalled. It's transferred to the car weeks ago, but I never get the prompt to initiate it.

Do I need to put my battery on a charger?

No we are not, we are referring to the 12v battery. For most it doesn't seem to help but it is worth a try.

Anyone tried installing via ISTA? Is it even possible? I have a '21 45e on 07/2022 and it says no updates are available but it sounds like I'm many updates behind.

[Nanometer]

My car wouldnt update for 2 years, I got close the last time and it told me to put the parking brake on... then the car just said "canceled" ended up bringing it to the dealer and after complaining they did it for free.

[Rocketmahn]

Long story short - after downloading and not updating for months I tried all options and even put the battery on a regular lead acid car battery charger until it was topped off.
It did not work....
A month or so later the download expired and I redownloaded it and again it would not update.

This weekend I bought a new battery charger with an "AGM" battery mode to use with my boats 12V AGM battery.....
hmmmm...
The X5 uses an 12V AGM battery and not a regular lead acid car battery...
I left the AGM battery charger on the X5 overnight to top it off to AGM battery levels. This morning I disconnected the charger and briefly started it up and when I shut down it wanted to install the update!

I think that using a regular lead acid battery charger doesn't quite get the battery into the voltage range needed for the update conditions to be met. When I used a newer charger in the "AGM" battery mode the update enabled and loaded. I used a NOCO Genius 5amp charger from Amazon but any charger with an "AGM" battery mode may work.

Will this update prohibit coding my 2019? It downloaded today but has not installed. Previous updates have failed to install and were deleted. At this point I don't care if it doesn't install as I have no issues and have my X5 coded the way I want it.

The only coding that is affected is not being able to turn off stop/start.

I’ve long given up on the update. I’ve tried charging and all that. But honestly I am not even sure it’s worth the effort cuz these updates don’t really change much.

[jad03060]

Often, the things updated are subtle, but in aggregation, can be significant. I know that after one update, the things like auto lane change became much smoother. SOme of the updates fixed potential safety issues like when you could open or close the roof or windows to help prevent potential injury, and one fixed a potential battery discharge issue when a module didn’t always shut off properly. The description does not always talk about every little thing that’s tweaked. The point being that you may be happy with the way it works, but you won’t know how it might be better. Then some if will depend on what options you have, and whether your actually use them…many people never use many of the functions their BMW can provide. People get used to certain things, and don’t either know about, or are interested in some of the things their vehicle can do…your choice. Personally, I update when offered, and so far, am about 50:50 on whether it worked properly or whether I was able to get the dealer to do it when it didn’t. They usually won’t do it if there’s not a safety issue addressed, but do sometimes. Depends on the issue you bring to service, and exactly what the status is at the time.

Thanks so much for this info. I'm gonna give this a shot!

The optimal charging rate, charging voltage, and float values differ between an AGM and flooded-cell battery…an AGM typically needs about 0.5VDC higher voltage, and can handle a higher charge current than a flooded-cell battery which is one reason you may need to code your vehicle to register a new battery…if you use the same battery, you still should update the date (essentially, that resets the age counter to zero), which also adjusts the computer’s functions on how it handles the battery charging and maintenance. If you don’t reset that age counter, the vehicle will treat the new battery like it’s potentially much older and worn, not optimizing the new one’s life and performance.

If you find it necessary to put a charger on your AGM battery, you really want one designed to understand its characteristics which are different than a flooded-cell one.

I had this on a ‘19 M50d, took it to the dealers under warranty to fix, feed back was “sometimes they just freeze, and it needs the hard upload to fix” nothing about battery condition etc.

Not great, but for me the work around was dealers 10mins away and a loaner for the day.

I went through this and thought I'd share my experience and solution. Remote software update had transferred from my phone to the car and was stuck at this stage for a couple months.

"Installed version: 03/2023.50

Preparations for upgrade version
11/2023.50 completed.

You will be notified when the upgrade can
be installed. Installation only when parked.
See Owner's Manual for more information."

I had met (to my knowledge) all the requirements for the update to install. This was not my first time going through this process and am fairly tech savvy. Even went as far as purchasing a trickle charger and got the battery up to 100%, according to the charger, and software update still stuck. I just gave up and planned to have the service department at my dealership handle it at my next general service appointment. With the help of BMW USA I was able to get these error logs from the car's diagnostics.

Fault code: 0x05110002
Specific fault code: 4
Fault description: Temporary rejection by fEPM due to insufficient charging state for RSU.

So what is happening is the battery(ies) are not holding sufficient charge to allow the remote software update to proceed. Or this is a software bug not reading the charge state of the battery(ies) correctly. The batteries are about four years old and still holding enough charge for the day to day needs of operating the car and they pass a diagnostic check so they do not need to be replaced at this time. Ultimately the service department had to manually update the software to get around this. Not ideal but it worked.

Conclusions. The iDrive system should make these failures more transparent to the user. It would also be nice to have a battery health portion of iDrive to better monitor this.

Anyhow that was my experience. Of course when dealing with software one person's issue may be different than another.

[jad03060]

Not all battery chargers are created equal…for best operation, you need one that understands the characteristics of an AGM battery as that’s what’s there from the factory. You might have changed it, and if done right, told the computer the current size, age, and type, but normally upon change, you only need to reset the age timer if it’s the same battery size and type.

And, yes, it would be nice if the user’s display told you why it wasn’t starting the update. While it generally is logged into the memory, without special tools, most of the things are not displayed to the driver, so he doesn’t know why and can only guess.

TurtleBoy,


I have a 2020 M50i that BimmerCode always worked with previous OTA updates with disabling the auto stop/start. But with 11/2023 installed it no longer works. Do you know of any way around it?.

Thanks.

No, no way around it coding wise. You have the button, that still works right? Some folks without the button turn off DSC to disable ASS.

+1, I agree. I'm going to skip the install if it EVER says it's ready. Not holding my breath.

Ok, appreciate it. Yes I luckily do have the button, & it does work. Just was so spoiled that I didn’t have to use it with it coded off with BimmerCode. I am going to contact them, curious if they are working on a way to circumvent whatever the OTA did to render it non-functional.

Check in with them. Last time we heard they were trying but nothing could be done, same for the other coding tools. My guess is BMW hid something somewhere that is inaccessible and that is why no one can crack it.

[jad03060]

It seems that with the newest s/w updates (or from the factory with newer builds), to be able to modify any existing coding requires an encoded handshake with the BMW servers, and thus, without that proper handshake, it won’t let you change certain things, among them, ASS. There are a few things that can still be modified, though. It appears things that could affect the overall efficiency are locked out from changes.

That is not correct. iD7 can still be coded. iD8.5, and some versions of iD8, can't be coded due to BMW moving to secure coding.
