SUBJECT
"High Battery Drain" Message in CID
MODEL
E60/E61 (5 Series) with N52 engine.

SITUATION
A check control message "High battery drain, increased battery discharging while stopped, vehicle may not start" is shown in the CID (Central Information Display) when starting the car.
Fault code 2DED "Power management, closed circuit current monitoring" is stored in the MSV70 DME (Digital Motor Electronics).
The vehicle starts every time, and there are no other symptoms of low battery problems.

CAUSE
The closed circuit current momentarily exceeds its threshold value when the TCU wakes up to perform the "Stolen Vehicle Recovery" function. This should not cause a discharged battery.

CORRECTION
Do not replace parts. A solution is being developed and will be published shortly.
In case of customer complaint, check the battery and recharge if necessary.
If the battery is low, then the customer may have an additional problem causing the battery to go down. In this case, carry out additional troubleshooting to identify and correct the root cause.
