With more than one owner having no luck L2 charging at home, (after a recent update?), there has to be corrupt firmware somewhere in the recent download that is impacting a (very) small subset of iXs surely.

He just finished and it looks like they're going to need to replace the CCU, just like for ok31. Some interesting tidbits for others that stumble upon this: 1. Apparently the shop just got another case of this issue on an i4, that it doesn't charge at their home or other homes, but does L2 charge at public places. 2. Apparently the voltage at homes is different than at the dealer/commercial (single vs 3 phase), so this is why my car was able to charge fine at the dealer with my charger boxes. 3. When I brought my car into the dealer last week and they said there weren't any codes, in fact there was a code but it was a generic "couldn't charge" code, which can apply to an issue on the car or charger. The service foreman brought an i4 and it was able to charge fine at my home, so clearly it's something wrong with the car. That things were working until the most recent software update was applied also leads me to believe that something with that update affected the CCU. It sounds like more and more reports are being surfaced as more and more cars are getting these updates, and I hope that others won't have to go through having to prove the entire matrix of charging/car combinations before getting traction. If you stumble upon this thread and are having a hard time getting the dealer to fix it, if you're able to get another car to charge at your home successfully, that should be enough evidence. And I guess point out the voltage differences in residential vs commercial power in the US. |

They told me literally they haven’t heard about this with anyone else so for now I’m waiting for the foreman to come once BMW gives the ok. Until then I’m not hating the X7 so they can keep my iX all they want. I’m on the better end of that deal even if gas prices in NYC are astronomical. |

Did they say what the voltage deviation was? A three phase circuit would supply a J1772 L2 EVSE with 208v while a split phase home service here in the US is 240v. Sorry about the CCU but I'm glad to hear there seems to be a path to resolution.

Im on the latest march that they updated but this all started when I asked for plug and charge (im only suspecting this because that was the only thing to change since last successful to first failed)

I'm on 03/2024.30.
The foreman didn't say exactly what the voltage difference was other than 208V for commercial 3-phase, and I know we have 240V at home. |

So what’s the latest? My shop foreman was out here today and looks like all error codes point to CCU but the NA engineer is being difficult and challenging it to say it’s my charger which we clearly know it’s not. Really frustrating.

I've had much better luck. The dealer was able to get approval, order, and receive the replacement CCU in only a few days turnaround, and I just got it replaced yesterday. Things are working again, thank god. Some interesting tidbits from the notes, maybe you'll find them useful: - "...the CCU is internally shorted and not charging at residential 240V" - "TSARA Requested the following test when the vehicle arrived at shop: 1. Checked fault memory. Faults stored for charging electronics. 2. Performed the charging history test plan, CCU charging test plan, charging check, and HV socket test plans. Found the vehicle only fails at the higher voltage of residential, 240V, and does not fail at the commercial voltages of 208V. CCU internal short and needs to be replaced. Closed session to send FASTA data." |

A threat to enact the LL along with giving them the info from above might well move things along! |

They’ve made some progress in evaluation though not sure what that is. Asked for additional time and patience. Going to oblige. Last edited by ok31; 05-03-2024 at 03:25 PM.. |

I’m going to give them a bit more time to give me some clarity. At this point really curious what the issue actually is and why I’m the only one with it so for curiosity sake dealing with it. They gave me a comparable vehicle to drive so I’m not that upset, yet…

Should you choose to peruse the LL process I strongly advise you to retain the services of an experienced LL attorney in your area. It should not cost you anything as the attorney is compensated by the automaker, not you or the selling dealership.
You have the choice of a refund of the full purchase price of the vehicle which can also extend to additional items you’ve had added, such as PPF you may have installed, or the manufacturer can supply you with an equivalent replacement vehicle. Using an Attorney takes all of the stress off of your shoulders, and I would never try to go through the process without one. Just something to keep in mind. |
