Software Update is 3.56.4.003

Fri Oct 02, 2015 8:43 am

Anyone know the details of what update 3.56.4.003 contains? BMW Uk only say 'There are many changes some of which we do not have technical description of. The change we are aware of are to the way in which the range is calculated, therefore making the range and actual mileage covered more accurate.’ They are struggling to give more info. I’ve said I want to know anything that is going to be changed that I as the driver would be aware of - such as changing the region which I do not want!

I am not 100% sure, but after the update the regen seem to be slightly less aggressive, and yes the rang estimation is different and for me it still underestimates my driving style. Additionally if you check the usable capacity of the battery in the hidden menu on the main screen, mine is now 19.9 kWh, which is an increase of about 1 kWh. So it appears the decided to allow us the use of more battery.

Mindmachine - thanks for the reply. I really don’t want my region changed unless they can make it more aggressive! I love driving without needing the brakes!

FWIW, with all of the things controlled via software, and different markets, it is really hard to say what functionality is in any one software build for a particular country. IOW, what may show up in one market may not always show up in others. The only way to know for sure (and it is sometimes like pulling teeth) is to find out specifically from the local country distributor or, maybe your local dealer, what is in any particular release. What shows up in a USA release, may never show up elsewhere and vice-versa.

To enter the menu, hold down the trip meter button on the side of the instrument cluster screen for 10 seconds. From then on, pressing this button means "next" and holding down the button means "select".

To begin with you have only these options available:

1 Identification
1.01 Conv. Index (1/mls)
1.02 SWFL 1
1.03 VIN
1.04 HMI Version
2 System test
3 Start roller
10 Unlock

To unlock the following menus, you will need the VIN from 1.03 above. Add the last FOUR digits together (other BMW models require adding the last five digits) to get your unlock code. e.g if your VIN is L12345, your code is 2+3+4+5=14. If that doesn't work, try adding the last five digits.

11 Consumption
11.01 Consumption dist. (l/km)
11.02 Consumption time (l/h)

12 Range

13.07 display value
13.07 tank phase. 1
13.08 Batt. Kapa. Max. 19.8 kWh (maximum designed battery capacity)
13.09 State of charge
13.10 Batt. Ladung (battery charge)
13.11 Batt. Anziege (battery meter indication)

Also note no mention of any increase to battery usability, just a different calculation.

While they did not mention the increased usable battery capacity to me either when I asked what changed, I found out by accident because, earlier before the update my capacity was 18.8 kWh and after it was 19.9 kWh. While I do not like the less aggressive regen, I feel the increased use of the battery is worth getting the update.

Despite being an upgrade freak myself, I have decided not to undergo any car firmware upgrades, unless absolutely crucial. I've now witnessed on a couple of occasions how much learning there is still to do for BMW i dealers - I don't want to lose my car for days or weeks on end because of problems with an upgrade that might have given me a little additional feature on my dash or maybe 0.5% more efficiency.

Never touch a running system.

100% disagree, if problems exist they should be fixed,and I have apparently a top notch dealer because I never have to wait for my car to be fixed. However I do not like the fact that the dealer can not tell us what the updated will do so we can choose.

However having said that a 5% increase in usable battery capacity is a big plus and I can live with the regen change that came with it. Another words, had I know about all the details I would still have given my ok.
