EDC Issue

[turbowrite]

Hi guys,
my e92 m3 has EDC malfunction issue.
EDC button does not work and I see EDC error message when the car turns off.
I believe this issue starts when I try to use cegar outlet to run dash cam.
I met many error messages after using cegar outlet. ex) battery discharged, edc and so on.
so I removed the cam from cegar outlet.
every errors are gone except EDC problem.
I have a Carly adaptor but I cannot see any error code related EDC.
I need your help.
thank you.
