Hello guys! I own a bmw 320d e90 M47 from 2006 automatic and i have some problems with it.
In november 2019 the car was in service and the guys from there changed a lot of things, they changed the glow plugs and the relay or how it's called.
After that car had no errors and it was driving perfectly. But in summer 2020 i was going in reverse in a parking and the car stopped , the engine stopped.
The car is automatic , what happend back then?
When i arrived home i checked the errors and i got this errors:
004212 , 004222 , 004232 , 004242 DDE: Glow plug , cylinder (1, 2, 3, 4)
003EED DDE: Power management, closed-circuit current violation
I cleaned the errors and i checked it again the next days and only the power management error appeared.
I got some infos that the error is the IBS , i replaced it 2 time and the error was comming back again...
And even now if i delete the error the power management error is comming back in a day or two.
I want to say that in February 2020 i replaced the battery and registerd it. The car had 77Ah battery so i replaced with the same one. But i read that it need at least 80Ah.
I have the battery for only a year and it's almost dead...

The problem is the errors appeared after a year.
I got the same errors:
004212 , 004222 , 004232 , 004242 DDE: Glow plug , cylinder (1, 2, 3, 4)
003EED DDE: Power management, closed-circuit current violation
If i got now to the car and i start it and run a test , the errors appeared as existent but if i go with the car 5 mins and check the errors again it appears no longer existent and i can delete them.
If i go the next day to check it again the errors are again existent.. I dont see any problem with the engine idleing. It hears good in my opinion. The revs are still.

What is the problem with the car? I need to change the relay again? And how i fix the power management error?

Hi, thanks for your post on 003EED DDE: Power management, closed-circuit current violation and 004212 , 004222 , 004232 , 004242 DDE: Glow plug , cylinder (1, 2, 3, 4)

I have an 08 635D with almost identical faults - mine cyln 123&5.
Also new battery.

Question: Did you solve this? and if so what was the root cause?

Any reply would be appreciated.

Thanks

Hey there !
The car had a GPS tracker that drained the battery , i removed IT.
Installed a new battery and repaired the glow plug relay.
And sincer then the car drove perfect. No more problems
