I think if you go for a long drive, 50-60 minutes at least - that should probably do the trick....

For the non-hybrid (maybe the hybrid also), keep in mind that it uses the Brake Energy Regeneration system for charging so during "normal" driving (acceleration, throttle use) the battery is not getting charged unless it is extremely depleted since the alternator is decoupled. The charging mainly occurs during coasting, deceleration, and braking.

I believe the hybrid charges the 12 V battery/batteries from the high-voltage battery.

Coding should not be required as this is already a part of the default configuration unless BMW decided to disable it or there's another bug. Either of which is possible knowing how many bugs seem to get introduced with BMW updates.

Yes you are correct. I called my dealer and told me that BMW decided to disable it for security reasons and new cars from Dec2020 will come with out those buttons.

BMW disabled parking lights for security reasons?

I am still not completely sure how this works. The manual says that with an empty 12v battery the 45e can't be started. Even with a fully charged HV battery.

So it seams like it can't charge the 12V when the car is switched off.

I don't know what happens when driving. Is the 12V charged by the HV or by the same dynamo that charges the HV battery?

Well, it's definitely rolling out. I got it about 2 weeks ago in my 2021 M550 and yesterday in our 2019 X5 (the FIRST remote update to hit that car since we got it two years ago).

Process went fine. I don't really notice any changes.

The 45e has no alternator to charge the 12 V batteries. 12 V is produced by the EME (Electrical Machine Electronics) from the high-voltage battery and/or the electric motor operating as a generator. I believe EME is not active when the vehicle is switched off.

I guess all the car electronics runs on 12 V and if the 12 V batteries (are there two of those?) are empty, the electronics can't start and enable the EME to recharge the 12 V batteries. Why can't the system activate the EME to recharge the 12 V battery if necessary..

I believe the same chicken and egg problem exists in many EV's including Teslas and Hyundais.

You are correct not an alternator / dynamo but the electric motor in reverse is charging the 12V / HV (like a dynamo)

And strange indeed that the HV can't charge an empty 12V when the car is switched off. Probably like you mention because it can't turn the 12V powered system on to activate charging.

Maybe it is also a security measure? If the 12V keeps losing charge for some reason and the HV keeps on recharging it, it might result in over heating / fire?

The electric motor is a high-voltage device, I don't think it knows anything about 12 volts. The EME works as a DC/DC converter (would be interesting to know the power capability of the EME).

But that is strictly verboten according to the recall notices from BMW!

[jad03060]

The computers in the vehicle, at least for now, run off of 12vdc. There's a 12vdc battery in the back of the vehicle. Without that being charged, you can't activate the locks, turn on the lights, or computers, and essentially, the vehicle is a brick.

When in the ready state, and probably during an active recharging session, the HV system can make 12vdc and charge the 12 volt battery, and because the system is making 12-v during the ready state to run things like the stereo as well, the battery should be charged.

But, it's a single point of failure...no 12vdc, no vehicle...same as with a typical ICE. You can put jumper cables on it, and start it up, though, if it was from a dead 12vdc battery.

Thanks! 30 min drive did the trick.

Successfully updated software. Took almost 1 hour
30 min to download to vehicle from phone
30 min for installation

I don't see Android auto under apps after the upgrade, can see other features as per release notes. I am guessing that's because I don't have Android phone.

This is not the case here in the US. I just did the OTA update to 07/2020.54 this morning and my parking lights work the same way they worked before doing the update.

What country are you located in?

[EV77]

I'm in Cyprus (Europe). The dealer told me that this applies to Europe and China. I am not sure if I can activate them through coding though.

I wasn't talking about cars affected by the recall :-)

I just did the upgrade without thinking of this
I had less than 1% and it updated just fine. Maybe not the smartest thing to do but it worked.
Also didn't give me any warning or headsup it needed to be charged.

[bqvalen]

Update bricked my G05. Wont wont start... all electronics power up but the car doesnt think it's in park so no start.
Now the problem is they cant get it out of my garage - it's parked on a plastic racedesk floor so they can't drag it. No room for traditional dolly, they are looking for someone that has smaller go jacks to get it out of the garage with a small tow truck then use a flatbed to get it to the dealer.

They will need this 8HP Transmission Park Release Tool to put the transmission into neutral. Check the service bulletin on the site below. Do not let them drag it out. Either dolly or preferably this tool.

I thought the conclusion that was reached is that this tool will not work on the transmissions in the G05, perhaps that has been revised.

Here is the G05 video and the tool:

wow that's awful news. There really needs to be a great big warning telling users to leave their cars in an easily accessible area in case it gets bricks the vehicle.
