Battery: Increased battery discharge when stationary.

[John-zzb27]

I am getting "Increased battery discharge when stationary. Electrical consumers were temporarily switched off." error message on a 2011 BMW 520D. The battery is probably the original battery. The car never has any issues starting and I tested the battery and it is holding over 12.5Volts.

The car also throws code:
S 0398 Power management, battery condition: Battery faulty or worn out

and code:
93076A Deactivation of terminal 15: upper stability limit reached, but deactivation preventer active

Is it worth further investigating a Parasitic battery drain, or just replace the battery? Would the Foxwell NT510 pick up a battery drain issue and if it's a burnt out battery?

I had this message come up on mine once before. I asked on a Facebook page I'm on and people were saying I'd probibly left the car unlocked overnight as they had the same message whilst on an overnight ferry where they left car unlocked to stop the alarm going off. I took it for a half hour drive and it hasn't come on since.

I guess it depends on how old your battery is. (edit - I’m guessing 8years based on post! D’oh).

I replaced mine in the M6 last year at 12years old, the 760 had it’s 2nd (9years) and the 330d I shipped to Cyprus (11years).

Dependent on how the car is used short trips vs. long trips, day vs. night, frequency of use can all affect how well the battery survives year to year. Lots of short runs in the cold and dark is a worst-case scenario. Start-stop doesn’t help either, nor efficient dynamics only charging on the over-run/braking (some models iirc).

If it’s holding 12.6v with nothing switched on, that sounds like a pretty good battery still. However, if it’s 11.6v it’s buggered.

You can get an OBD2 plugin solar charger on Amazon (etc) for around £30. If you plug one of those in and it goes away, then it’s either a tiny parasitic drain, or it’s got warmer while waiting for it to arrive - this is a bad time of year to fault-find.

For the sake of £30, I’d get one & try it for a couple of weeks to see if it goes & doesn’t come back. If it keeps coming, it’s likely the battery. 8 years isn’t a bad run.

Thanks for the replies, the battery is old but it charges up very quickly and holds a good voltage

Here are the error codes I am getting:
93076A - Deactivation of terminal 15: upper stability limit reached, but deactivation preventer active
93076B - Deactivation of terminal 30B: upper stability limit reached
93076C/Intermittent - Deactivation of terminal 30B: upper stability limit reached, but deactivation preventer or legal load/consumer active
B7F86A/Intermittent - Gateway sleeping is prevented
8011FD/Permanent - Ioniser. Signal line, short circuit to ground or open circuit
801222/Intermittent - Air conditioning compressor: Switch -off due to missing DME/DDE release
E14A6/Intermittent - No message (status ambient brightness 0x2A5), receiver KOMBI transmitter JBE/BDC
8020E6/Intermittent - Ignition on: stability limit reached or ignition on for a long time
8020E8/Intermittent - Reset or deactivation of terminal 30F

Looks like "8011FD Ioniser. Signal line" is the only permanent issue, how can I disable this on the fuse box?

I would recommend getting your battery tested with a proper battery tester. Measuring the voltage is a very limited guide to battery condition.

A proper test will let you know if the battery is faulty or not and if any further diagnosis is needed. If you CBS a new battery will need registration.

Battery change likely. Had a few of these messages near the end of the life of the battery. Use either a dealer or a good BMW specialist, isn't that easy changing batteries on these and can require coding.

[cossy400]

We ve got this on our 66 plate, X4.

BMW have had it for 2 weeks, "claimed" it was the battery and have changed it for a new one.

MRS400 fetched the car on Thurs and its come up with the same problem again.

Im just struggling to see how the battery has lasted 3 days if it was "new".

Something must be consuming the battery whilst you are away from the car overnight. At night, when parking the car up, lock it and leave it for about 20 minutes. Do not touch anything on the car. When you get back after 20, if you look inside the car the hazard button light and the start-stop button should not be lit. If it is lit, the electrical consumers are still running at night. The car should be going into a standby mode where all the electrical consumers are turned off for the night, to prevent battery drain. Car immediately wakes up and starts the iDrive computer up as soon as you unlock it. If it stays on overnight, there is an issue with something electrical remaining on overnight. It could be anything, from a module to the iDrive system itself.

My 335i convertible started suffering this same problem after I took it to BMW for the recall "re: battery clip problem". I just ended up getting a trickle charger that I saw recommendations of on this forum.

[cossy400]

So BMW had the car for best part of 2 weeks, changed the battery and we picked it up on the Thurs at 5pm,

MRS400 used it for work Fri, Sat the car got parked up as we had to go out in the Fiesta as it was due its service and 1st MOT, so the BMW was parked all day.

Sunday got in the BMW to go to SILs, "battery discharging while stationary", BMW had it back in and apparently the memory hadn't been cleared (I assume shes talking fault codes).

Got it back Fri went for a good run yesterday and now we are off on a pub bus tour, so its parked up, so we ll see if its fixed.

[cossy400]

So after my last post, it lasted 2 days.

so off it went back again. they had it for another week before ringing up to ask if we knew it was fitted with a tracker?

My response of NO it hasn't and even if I wanted one fitting you 've had the car longer than we have, (service manager didn't see the funny side)

So they 've removed the tracker and touch wood it's been fine so far.

Or thou I have sent a stty email as the service manager decided it was a good idea to inform me that there's nothing to pay, as car sales are paying...

I wasn't having a good day and for him to think he was cheering me by saying it after they 've had the car longer than we have, then he's sadly wrong.

A new Bosch AGM battery solved the issue, no more codes!

[V5Ade]

I had the same issues randomly for several months. The battery was replaced by BMW (£600) but I was still getting codes. It turns out mine were being triggered every time BMW Online services were being updated due to things like subscriptions expiring or adding new services.

Hi, I have a BMW M sport 1 series, I keep having this error message - Increased Battery discharge when stationary, even though the battery is brand new, if I do not drive my car daily I get these issues and after replacing the last battery it totally died on me within 2 years and wouldn’t start at all, had to get car towed to garage.
This has been investigated by the BMW main dealer, who replaced the battery again only 2 months ago.
Spending too much on this.
With the coronavirus the dealer isn’t open until June the earliest.
Any advice would be appreciated.
Thank you.

[E-bmw]

If your daily journey isn't long enough it is probably taking more out of the battery than the car is managing to charge the battery by.

[Ninja59]

Hmm, there will likely be something draining it, if a new battery cannot last that long I would be worried, or alaternatively they have not programmed it (which they should have!)

[DSS.BMW]

Hi,

I have had this trouble for the last week to. I Have F20 118i Msport 2017 30,000m. Went for a drive to see if it would help but still get the message. Cannot book with BMW to look at it till June 2(this is their earliest booking dates they are giving). My warranty has run out in the coronavirus lockdown. Any advice on how to fix or what to expect from BMW would be much appreciated. I’m not wanting to pay for a battery when the vehicle was initially booked in 4 weeks ago and overlapped on warranty, what a coincidence. Thanks

regards

Dan

there’s a 3 month extension on the manufacturer’s warranty , for those expiring during lockdown.

As your car is operational, I doubt recovery would attend. But if you do break down that’s extended too according to the link.

My 2012 335i started giving me this error last year and I replaced the battery and still had the error. Turns out the water pump was draining the battery. It was replaced and fixed the issue. Apparently they are known to have this problem. Hope this helps!
