They're on my 08 535xi

The car is completely stock. The battery dies after about 2 days. The last time I drove it was either on Sunday or Monday. Then I go yesterday and the battery was 100% dead.

Here are the error codes I pull up.


2DED,8,Power management, closed-circuit current monitoring
2DEC,2,Power management, battery monitoring
2ACC,1,DME master relay, shift delay


Any ideas/suggestions?

Thanks

 

It sounds like your battery is going out. Have it tested at an auto parts store.

 

2DED could be caused by any aftermarket electronic devices you have in the car. If they are using power from the constant 12v battery terminal instead of switched 12v power, then they will consume too much power and throw 2DED codes.
I'm not sure that alone would cause codes 2DEC and 2ACC though. I'll have to do some more research but I'll let you know if I find anything out.

 

Thanks. I'd appreciate whatever info you're able to get for me. I've been searching. There's nothing plugged in and there are no aftermarket electronics installed.

Also the battery is only a couple years old

 

Also some other things I tried:

- i removed the battery and used my battery conditioner on it. Took a while but the battery came back Full and in good working order.

I also registered the battery with my software.

 

Just an update. I had the battery sitting on a conditioner for a couple days.
I hook it back up in the trunk and checked codes. The codes were:
the ACC code went away, but i still have the following:

2DEC,2,Power management, battery monitoring
2DED,8,Power management, closed-circuit current monitoring

 

sorry to bring such an old thread back to life, but I'm having the same code. It comes and goes. no check engine light. A few weeks ago the car turned off while I was driving and then would not restart until I pull the key completely out. After retarting the car, it would drive with no issues unless

 

I spent several hours troubleshooting wiring. At the end of the day, it was a faulty IBS. All I did was disconnect it from the positive terminal and the battery never died again.

 

these are some of the others I received. these code only showed up a few month after a deer hit the passenger side of car. only showed up once. I cleared them and then never again. what so weird is that the car runs fine with no check engine light.
