I have gotten the same code. I saw it the first time today after installing a JB4, DCI and ER CP. Other than the misfires ive gotten from having dirty plugs, I hadn't seen this code before. I haven't installed anything that draws on the power supply. The only thing that I can think of is that I have an ipod that stays connected constantly, however, I have had it in the car for over a year with no problems. Anyone care to chime in on a more succinct cause?

searching for the code normally helps.... you have to see that probably lots of people got it and found a resolution especially here on e90post.

i was getting this code off and on for 2 years, then it never came back. I found no solution, im sure theres nothin to be worried about. My advice Just ignore it .

Diggin up an old thread here - this afternoon I got this same code and began my investigation with you, my support group.

The previous owner of my 07 335i hardwired a dashcam, which is supposed to have an auto shutoff, however, lately I have noticed it behaving eraddically. I’ve unplugged it for the moment, as well as my kinovo Bluetooth adapter and will be monitoring the outcome. Hopefully this is the solution, as it seems to be the most logical cause that I’ve come across since most others mention a bad battery or something related to that, and my battery was just replaced in August.

I’ll try to report back in a few days with any changes.

Turns out it was a precursor to my water pump & thermostat going out. Pretty sure the hardwired dashcam & bluetooth adapater were just coincidental.

This just popped up for me and no engine light nothing.
IIRC I had just scanned for channels in the tv option in my I-Drive
I cleared it and I’ll see if it appears again

From trial and error could it be leaving something plugged into your OBD port?

[DiskoSleaZe]

I'm hoping it's this. I just realized I left my OBD cable in too..

If you have a k can OBDP cable plugged in at all times this will cause this error message

Has anyone seen 2DED after installing catless downpipes with an O2 sensor mod attached to the ECU?

I fit this description and I do get 2DED often (Tho in the younger years I never saw this code and was of this configuration as well).

Only thing I can think of is maybe my cigi lighter usb charger has a tiny blue led and that might trip it. I always leave my iphone cable plugged in even without any phone connected as the car is asleep. I have a usb device hooked up to the aux audio usb jack and that also gets charged when its powered.

Hi guys, my n54 e92 is throwing the 2DED code when I get near red line and car goes into limp mode. I've only got a jb4 but no other bolt-ons yet. Also, there's nothing plugged into my car that could be draining the battery and I've just replaced spark plugs/ oil and cleaned solenoids.. anybody have any ideas why this is popping up?

I left my Carly bluetooth adapter plugged into the OBD port overnight. pretty sure that's the culprit.

So my AGM battery was changed around Nov 2014 and 105k miles ago. The battery seems to hold about 12.3V over night when I check with the hidden menu in the Kombi.

I would get 2DED and would hear my head unit CD player eject on car start up often. Now that the season is changing my car is also getting 2EF4 codes. So now I am now monitoring my coolant temp in the hidden menu 7 on the Kombi.

Last night I decided to go module by module with inpa and clear out all the error history. Keeping the car on a battery tender over night seems to have helped this morning. But I need to keep doing this test for a week to see if it actually made a difference.

I got this code recently, repeatedly in an '07 E93.

The cause seems to have been a combination of leaving the Carly BT Adapter plugged in (I have been leaving it plugged in most of the time for ~3 years) and my battery being 6 years old.

Recently I noticed, just very occasionally, the battery symbol lighting up when the car was left with the ignition on and the engine off even for ~30 seconds. It never used to unless it'd been sitting for much longer than 30 seconds.

So I think people get this code when either something draws a decent amount of current and you have a good battery or when there are small draws of current and your battery is ageing (or is low for some other reason).

If you get this code while the engine is running, especially at HIGH rpm, then change/fix your alternator/voltage-regulator IMMEDIATELY.
