That does make sense, but interestingly this is the only sign I have that I might have a low battery. No struggle starting and any other signs. Of course, I've had batteries go bad with no warning signs other than not starting.

Are there any cheaper battery options other than OEM? Not even sure if a non-OEM battery can be registered.

Yes, plenty of options for main battery, from different manufacturers. There are two different options, if you keep the same battery type you just need to register it, if you get a bigger or smaller one (form 90 to 105 for example) you need to code a new battery size.

I came to realization that it actually never "disappeared" , but there is a glitch where hud was pushed way down(repositioned), so i go into the setting to adjust the position of hud, and raise it up to the "max" , but still it was way too low, literally could only see half of numbers showing the speedometer, when playing music i could see previous/next options as well. Now the main concer is why did this happen ? why did my hud randomly got pushed all the way down without abillity to bring it back up to normal hight where it was and worked perfectly, right now the highest hight setting is still way too low where i can barely see half of numbers, and i'm 6'5", even tried to reset the car to factory defaults( options-->delete all user data) and that didn't fix it, it is still there but way too low, so for people shorter then 6' it will look like that it's not working at all, but it actually is working, it's just super low, so far i have no idea how could this be fixed ?

I saw a video where the guy shows a spring that control the high. The spring holder broke and that was the reason for not been able to adjust the high.
I am in here because my HUD goes off, has come back on, but spend most of the time off. Just got the car a month ago and problem started a week ago. I guess I will have to check high of HUD, battery and fuses... anyone has a link for a technical info?
BTW, what is the best scanner we can buy under $600? thanks

Autozone can check battery for free. Any shop can do that as well. 90% that the problem is in battery.

Same issue with my X5's HUD.

When it happens I go in the settings and I play with the height and rotation of the display and it comes back right after. Dealer is clueless on the reasons why it's doing that.

Mine did that at first then it proceeded to get worse. HUD would only work 1 out of 3 drives. Replaced the battery and she's worked solid ever since.

Hello all, I was having the same issue with HUD going off and on. Come to find out in my situation, my battery voltage was low and it shuts the HUD down to conserve power. Once batteries were replaced, I haven't had any issues. Hope this helps

Replaced battery at 120,000 miles after 7 years and problem solved

My HUD stopped working. I found a thread that mentioned going into the iDrive Settings, then HUD, then you can adjust on/off, up/down, right/left and then brightness. Now everything's working perfectly

Just noticed this HUD problem this morning. Nothing displayed, playing with iDrive display settings didn’t do anything.

Had battery excess drain warning come on when started car this morning, but this is normal for my X5 anytime I leave car off for more than 12 hours because I have 2 cameras wired up and recording.

2 things were different today:
1- didn’t not drive car at all yesterday (normally drive daily)
2- temperature was coldest of year, around 40 degrees F at start (except in March when took it through Rocky Mountains)

First time had issue.

About a month ago ran battery down so bad with A/C electrinics running for over an hour that car barely started but resolved after running it

Since others report a new battery fixed it hopefully that is the issue.

Has not come back on yet but will try it later today and tomorrow

Ironically, this issue occurred on my way to the BMW dealer for three-year oil change contract service. I did not ask them to take a look at it. Thanks for the info here.

Upon getting the car back, the HUD was still not coming back on and not working thought after letting it sit for a while and then turning it back on it would work but no.

Instead, I went into settings, turned off the HUD lock the car walked away for about 10 minutes. Came back, drove off and went back to iDrive and turned back on the HUD.

Fixed it.

HUD working normally again now.

Thanks everybody for troubleshooting in the forum here very helpful!!

As you discovered if the car is having constant battery issues, the hud will be off permanently until you turn it back on manually. I was driving around for best part of a week, with 2x dead batteries and starting via a jump pack. After I replace the batteries, the hud would not comeback until I manually turned it back on.


On to you battery drain issue, you should probably look into that. Just wire up you Cam properly to something like neo. Mine is in the area under the fuse panel in the trunk (sitting vertically). For any other accessories, just connect in via relay.

If you don't drive enough to charge the camera batty stack, you could wire something up to charge only this battery and not charge/wake and accidently fry the rest of the car.

Good recommendation. Right now as long as I drive the car about every 12 hours, Then it doesn’t have the increased battery drain issue. But it does deactivate the comfort access controls if I go beyond that time and I get the message. It seems that the next level after in this case, letting the car sit for over a day was to deactivate the HUD.

I installed 2 Garmin Mini 2 Cams front and back. Cool thing about these is I assume power demand is relatively low because there’s no screen, But even easier on the install is they make an OBD2 port Power adapter for the USB powered cameras. so all I had to do was wire the USB cables to the dash just above the OBD port And plug it in no splicing or risking messing up my wiring for something that is above my know how.

So Neo battery is the protagonist in the documentary called the Matrix?? He was a battery too ya know

Or DJI makes a Neo named battery pack? So you can wire that up to charge when the car is driving and then power the cameras from that? Doesn’t sound extremely hard, but not easy either. Mine does not have the auxiliary second battery. Maybe I should consider adding that If it would help the situation with the cameras?

Your new batteries should be able to last more than 12 hours if its only the cameras running. Even in full ON state, the cameras don't use that much power. For giggles, with the cameras unplugged, see if the car lasts more that a couple of days without been driven. If* it is the cameras that is draining them overnight, it is still not good for the battery.


Onto the neo. ie Cellink Neo/Blackvuew/Thinkware/etc are the common camera battery types (all same). You hardwire the battery to a switched circuit (something that only turns on when the car is on).

Not familiar with the Garmin but if they have park mode, these batteries will put the camera into said mode. They have a 3 wire connections that feeds the camera the grnd, acc, constant. When the battery looses its switched connection (car turned off) it removes the acc, but keeps the constant to the camera. If the garmin has park mode, this would put it into it.


Here is a couple of vids to give some ideas to google. My neo is added like the video via the fuse add, into something for the rear seats that is switched (need to check exact fuse #).

Note* if do go via the battery route, don't use the cig lighter connector, use use the 3pin hardwire. If you use the cig, the camera will be constantly on.
The batteries have an extenders/expansion units, those only add capacity to the main units. Only the main units have the camera out, and charge in.

This is outstanding thx a lot!

I recently have had the car mostly working reliably even with evident relatively weak battery. With added cold to 40 degrees recently this adds to it. It also seems to want to pre heat prior to ignition which presumably wants more power. Prior to adding the little Garmin cams (no screens on these) battery per bimmerlink was about 80%. Several months of daily use and battery health after short drive is 45%.

Have been considering new battery but dealer quoted $645 LOL and was planning on doing myself anyway…but first….

Wanted to try one of the battery maintainer trickle chargers to see it can rehab first though. Seems good got CTEK. After a couple hours it’s at level 4 good supposedly holding constant voltage 14.2 then. Battery at 55%. Overnight will be interesting to test.

Usually drive it daily and if it’s less than 12 hours between drives usually it is ok, no excessive discharge indicator..

Fyi on parking mode. I’m not a big fan so these are actually setup and wired up both to the front OBD port and are constant on. So not too bad the little things are mostly ok up to 12 hours. 1TB storage. But will be testing this out looks like
