As the dealer confirmed to you, programming will be necessary in order to eliminate this "annoyance". Given it is the BDC module and its importance, I would personally opt for the update but that is my viewpoint. Ultimately and rightly, it is your decision as to whether you want the issue solved and are "prepared" to sacrifice on the for many "glorious sound" or want to keep it in the current state (with great sound especially) thus willing to put up with that error and anything else which may arise as a consequence (as you say trickle charger acting weird and the like). Of course an update brings other benefits such as some of the latest tech which just like magic gets introduced/activated for free even on 2019 models since they share the same hardware (MY2019-2020). Fact is noone can and will force you to upgrade. |

They just indicate a generic fault but we do not see the actual fault code returned by their short test. Based on that code, the BMW technician dealing with the car should know what to do next especially after querying ISTA D (the official BMW diagnostic software) for a service plan. At least that is the standard procedure. So my "guess" is if they officially advised on programming, they found no hardware issues (the ECU should thus be fine) but rather a software related bug as we commonly know them outside of the car world too. |

In fact back in 2016 at MSI we started pushing full updates to our remote "command center" and network installations to eliminate the need for field service technicians to upgrade them. At the time the field techs viewed it as an attempt to replace them but that was never the goal as they still are 100% required from a break/fix perspective. The same goes for BMW as software is perhaps roughly 15% max of what keeps the car running. Flip that to Tesla (or any true EV) and then it becomes a game changer.

Good points in post nr. 49 Blooze. My experience also shows that you need to talk to them for a few minutes and already know whether or not you are in the right place. When a SA told me they charge 600 Euro for flashing the whole car, it was clear to me I would go somewhere else where I only paid 1/4 of that price. In some cases (like with wife's G02 and my M850i) the dealer did it for free (one was in Germany, the other here in Switzerland). On another occasion and BMW dealer, back when my knowledge wasn't sufficient beyond simple coding, other than charging a minimal amount, they actually provided me lots of information and detailed stuff which got me more and more interested in the subject thus pushing me eventually to explore further. As many here already said, keeping friend with you own SA helps but they must be competent else there is little or no gain. In general, though trained, they aren't as acquainted or as prepared as they should be. On the other side of the coin, call me old-fashioned but I do not like someone "injecting" software into my car remotely without actually knowing what is being updated. I like to control the process myself and many others in the BMW community do too. I am glad a lot of self-service can be done with our bimmers not sure the same goes for other brands. Despite them not being perfect, I wouldn't trade them for any other brand/s.

Not sure BMW did that (they might have not) but I was thinking actually re-coding the ECU (VO code ecu) would be worth a try and take maximum 5 minutes including all the preparations and the procedure itself which would last 15-20 seconds. Now if they mean flash/update ecu when using the word "programming" then in his case they will need to flash the complete car for the other ecus' dependencies and not only (old IStep Level as well). |

You could however ask your dealer for this detail and say to them whether "they can only update the BDC ecu without touching anything else" and if there are any consequences in doing so vs. what they recommend - just to hear their official version. Updating the BDC probably takes somewhere between 10 and 20 minutes only whereas the MGU headunit can take a whole hour for example. |

Sorry for the confusion but yes the lowest common denominator is hitting all of the US. Here in AZ the only law on the books requires a "working muffler" vs the others that have a dBA limitation regulations. Hence, my M850i was neutered and understandably as it would be a logistical nightmare on BMW's part to try and isolate the updates to owners in specific states. In fact as far as I understand BMW views the entire US as a region so anything coded for it will get applied universally across the board.

Well after a number of weeks of slow progress my car has officially upgraded to iDrive 7.
I've lost all of my coding, via Bimmercode, so that will be a job for the weekend. Very pleased to say the PWPS's are still working a treat and I'm still startling a few people sitting outside at the local cafe. One feature - which seems new to me - is the album carousel for my music. Love it. While I've got a stack of playlists, sometimes its nice to listen to an album or give passengers a chance to go through the carousel and choose. I'm just exploring what the BMW assistant is able to do and will revert if I uncover anything exciting. |
