Anyone has any advice on the battery drain message? I recently installed a dashcam at Cartoys. Apparently, it draws current in the PARK mode as well and this I suspect to be the cause of the problem. When I start the car, this message at times pops up. :dunno:

Cartoys told me they can disconnect the PARK mode, but that means it would not record if there are any incidents to my vehicle when parked. It would only record and work when the Vehicle is started.

I like to know if you have any similar experiences and if this is a negligible issue. My X5 is still under warranty btw and want to make sure it does not void anything.

thank you

Increased Battery Discharge is enabled with > 80 mA closed-circuit (BMW for OFF) current. The current detector is in the IBS and the only way to prevent the IBS seeing it is to not use the IBS. But then the BMW charging system wil not even try to replace the battery capacity that bypassed the IBS.

BMW documentation makes no mention of a "PARK" mode. Somebody's blowing smoke ...

Too late.

These 'car stereo specialists' are some of the worst hacks around. I amd sure THEY will tell you now worries... but you go to BMW with any electrical issues I'll bet money they point to 'oh that dashcam'

Let me be helpful... how much current SPECIFICALLY does the dashcam draw in park mode?

Do you notice this happens only after youve been doing a bunch of short trips??

How old is the battery? What is your driving use like? 5mile trips or 50 mile trips?

Thanks for your responses.
I have disconnected the unit's power cable and the message does not seem to appear anymore. A couple of more trips and I can confirm.

The dash obviously draws some small amount of current to keep the unit alive just so it can start recording should someone hit my vehicle when parked. I have observed the message even when parked at my home's garage overnight.

I am not sure what the current draw is when the vehicle is powered down. The manual does not specify it.

What do you guys think?

I can take it back and have them rewire it so that it does not draw current when vehicle is not running. The downside is that the parking feature on the unit will not work.

The model is compustar CD 3200. Also by PARK mode I meant when the vehicle is not running.

I have had the cam for only a week. It happens for both short and long trips btw. my work is 25 miles.
Thoughts?

Thanks

It sounds like you've narrowed it down to the dashcam. So you need to decide if you'd rather be burning through $200+ batteries regularly to record stuff while your car is off, or not have your dashcam record while your car is off.

Nothing anybody will tell you here will change the above scenario.

Itseeps OP has the following constraints on his decision:

1. Enable or disable parking mode

2. No furhter investigation is possible nor warranted.

Personally Id be interested to know:
1. what are the specs for current draw for THIS unit
2. What is this unit actually drawing
3. Are there disfferent circuits on the BMW that would 'allow' higher current draws without tripping a monitor
4. If I parked in my own garage at night, I might install a switch (or only use park mode when I am actually parked where I might get bumped)

stuff like that.

Edit: Have you done much research on that camera compared to the current state of thee art??? They seem to be focussed on the 'retail unstalled market'- not much available online in terms of hard specs/manuals...lots of 'visit our retailer'... 720p?!? Your issue may be that it is basically running at full current during park mode with the various detection modes it runs, not a low power standby.

Take a poke around other subforums. I believe this is a common problem with aftermarket dashcams.

Is there a timer setting for the park mode? Others have fixed this my setting their particular model to <6 hours.

My hardwired blackvue causes such message if left overnight or longer. It can be safely ignored - the only consequence is an error code that won't trigger CEL... and obviously a dead battery if left for weeks (months?).

P.S. and it doesn't void warranty unless you have an issue with something particularly connected to a plug/wire you've tapped to and a dealer is in a bad mood.

80 mA is 0.08 Amps times 24 hours is about 2 AH per day and fifty days from a 100% fat battery to dead, dead, dead.

Only a battery regularly smart-charged can be at full capacity. We don't know that the CarToy's dashcam draws 80 mA, but only that it draws more than 80 mA to trip the Increased Battery Discharge warning.

Excellent responses, thanks it gives me so much added insight.

My initial concern was if it could damage any of the circuitry of the X5. If that is not at risk, then I have no problem spending a little more time exploring options.

Since the current draw is not specified in the manual, I plan to call the manufacturer tomorrow (today they are closed) and ask for some clarification. I will ask if it exceeds 80mA in Parked mode. Also, I am going to explore playing with the dashcam settings to see if I can minimize the current draw. I do have it at max sensitivity right now, so perhaps I can make that lower and then observe behaviour. I have had it for about 6 days now, so still learning about the unit.

I am a little relieved to learn that this is a common problem as TroubledGnome mentioned above. Also ARD pointed out looking at other 'circuits' that may not trip the monitor. Good one to inquire about.

On a side note, I drive in very congested and aggressive traffic every day. Some of the driving behaviour of my fellow drivers have been illegal and this unit was purchased with some level of added security in mind.

Here is the unit I have: http://www.compustardash.com/

Inquire here- I dont think the mfg or cartoys are the experts on BMW circuit sensings... I just dont know.

I have seen installs for carcams done with a secondary battery ONLY to run the park/security mode-pretty simpy- the carcam is attached to the battery, it powers the unit 100%- when the car is running the car provides the current so you arent depleting the battery, but when you turn it off the cam only uses the secondary battery- it can NEVER leave you with a dead car.

Like this:
https://www.amazon.com/LUKAS-LK-530-12V-Battery-Potable-Blackbox/dp/B00CHYKOD0

Im sure the experts at Cartoys have experience with this and discussed this with you before hacking into your wiring, right? :angel:

Of note, this is the BEST case for the main battery lasting. The current draw is likely more than 80 mA by quite a margin. The car's modules will also draw the usual 20-50 mA when off.

I'd be surprised if a 100% charged battery lasted a month with this thing going, and the average E70 is going to have a much lower charged battery than that, so it could be only a couple of weeks or less to flat.

The car likely won't turn over with that final few days of power draw either, so figure that'll further shave the time down if you want to actually jump in and crank the car up.

I know you can't help yourself but you don't know that. Seems more likely that they're referring to the dashcam's park mode, which makes sense in context.

Not much to do here except disable it in park, add a secondary battery, or live with the warning and hope the recharge is adequate.

What is it in this thread that I don't know about BMW electric systems, please?

There is only one current detector, the one in the IBS. Nominal BMW closed-circuit current is 20 mA. Closed-circuit current >80 mA will set Increased Battery Discharge warning.

There are four BMW technical descriptions of the battery and electrical systems at Luca Paindelli's G00gle Drive site.

In my career it was imperative that I/we know what we did not know, that we understood our known-unknowns. If I don't know something then I'll either say something else or nothing at all.

... As I said. Thanks.
Ha, dude, you're really not following...

"Cartoys told me they can disconnect the PARK mode, but that means it would not record..."

Sentence structure would indicate that "PARK mode" is in reference to the camera. Whether or not BMW documentation makes reference to a PARK mode is irrelevant and doesn't indicate that anyone is blowing smoke. Of course there's no reason to give you a hard time about this except that your general disposition rather warrants it.

Don't mind Doug. He's just masterfully playing his role as the most obtuse engineer ever to post on a BMW message board. :eek:uch:

Thanks for everyone's enthusiastic participation and helping me resolve this issue.

I have some potentially good news. I called the manufacturer and they told me the camera has settings that have already taken my situations into consideration. There is a voltage threshold setting on the unit that was set at 12.0V. Tech support asked me to increase it to 12.2V. When the unit detects anything below this voltage it will powerdown.

On closer reading of the 6 font users manual, I saw this "Standby Voltage:when the battery voltage drops below the voltage setting in the ACC OFF state, the main power shuts off".

So I have now connected the unit back ON and increased the threshold to 12.2V. I will observe it for the next few trips and hoping for the best.

Also, I noticed there is another Timer setting to power the unit off in ACC off mode. This timer is set at 6Hrs. I can reduce it and see if that works as well.

I will report back on my findings.

thanks.
