Because bmw wants to OTA a version they have exhaustively tested.

This thread is about OTA. Was your version installed as OTA or dealer?

TJ_BMW - I would call BMW and ask them why it is upgrading you to an out of date software version in Australia - just so you can confirm things are working correctly. It may be that it need this intermediate release installed to get to the latest 11/2019.40 in Australia.

07/2019.75 is the latest and only ota update currently available. Later versions are available at dealers but not OTA thankfully. |

It's always easier to go up instead of trying to go back. I do agree with BMW's logic (for once) as to why they did this. This way, the dealership puts it in, makes sure it took, and then you're good to go.

07/2019.75 is the latest and only i-step available OTA. OP had the latest update available via that method. 11/2019.5x is the latest globally available i-step for the G05 and can only, currently, be obtained via a dealership visit or DIY ISTA programming. The OTA updates are n-1 meaning they are one main branch version behind the latest available version. This is presumably to reduce risk when delivering updates remotely. |

IFR - I think it is more nuanced than this.
if the latest software is reliable enough to be instaled at a dealership, it should make no difference - if the OTA process is itself reliable. Only other reason would be a n+1 requirement, in which case a subsequent OTA would be expected. |

Regardless the facts are the facts. There is 1 version for OTA and a later version for general upgrade. No need for any further discussion. |

IFR - not sure how technical minded you are.
The OTA file transfer protocol must be reliable and error check the received file with security certificates before activating and migrating to the new image. Without these mechanisms no manufacturer would contemplate OTA image upgrades |

The point I have made repeatedly is that you advised the OP to check with BMW as they had an out-dated update. I corrected your advice to save the OP wasting time as THE ONLY AVAILABLE OTA UPDATE IS 07/2019.75. If you have received that OTA update then you are golden. You want a later i-step then you need to schedule a dealer visit, or use ISTA/esys to program the car yourself. The OTA delivery method is not what I am talking about. You mention it, and It's an interesting topic, but not relevant to the point I am making. I reiterate, and for the last time, BMW deliver the n-1 OTA because it's had 3 months of live in the field testing. It's that last bug fix iteration of the previous main branch release and is as reliable as that version can be. The latest versions are released to dealers in a controlled and managed environment and issues can be resolved either locally by the technician or remotely and collaboratively with BMW dev. There are dozens of combinations of i-step, region and models that each i-step update has to address, plus different hardware based on options. That is where the majority of the risk comes from, not the OTA delivery method, which is pretty solid and consistent. It is still a risk but minor, for the reasons you outlined, compared to the risk of an untested update breaking the car due to an unknown configuration issue. If you review the I-step programming release notes over the past 12 months it will become apparent where BMW have issues with i-step updates, and its not because a CRC or cert check is failing during an OTA update. |

IFR - the OP is all about OTA.
It seems you are talking about something unrelated to the OP. The question remains why OTA is not delivering the latest release. There is no good reason provided why this would be the case. |

He has explained this quite well. The OTA is one version behind the latest release and its patches. For example the current latest release is 11.2019, the OTA is 07.19.55. This is done to ensure there are no issues with vehicles being bricked by faulty software. If you want the latest version, you need to go to the dealer. The reasoning being if there is a fault the dealer is better equipped to fix it. N-1 makes sense. |

I'm OK with N-1, the reasons make sense, especially if its only fixing non critical or safety features.
If something is in that critical or safety category, then that warrants a visit to the dealer service department anyway. |

Tesla does not do this and a robust OTA process would allow BMW to avoid as well.
If you think that the OTA process is not robust and not tested thoroughly by BMW, then you will be happy that only N-1 is supported. |
