Is this the dealer on the east side or the one by the International District?

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.

Eastside (BMW of Bellevue).

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.

Im glad finally to learn I’m not the only one, sadly. Got a call from my service advisor letting me know like you that the foreman will have to come out with some test kit to verify why it’s not charging at my house. I told them this weeks ago but now it’s BMW NA getting involved because they want to understand what’s going on.

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.

Thanks for keeping us posted!

I am just concerned it took this long for them to see/find the fault codes considering how easily you could reproduce the issue with your setup.

It’s in the really slow boat to solution.

Good to hear. I used to have good luck with BMW of Bellevue before AN bought them out. I was a bit surprised they would take the extra effort to come out to your home. They're closer to me than BMW Seattle but that's my go to dealer now.

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.

[thebishman]

What software version are you both on?

[ok31]

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)

03/2024.42

[Toastmaster]

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.
