Mercedes w211 2004 E270 CDI front doors controle modules battery drain.

Hello. I noticed that the front doors modules caused battery drain. I figure out that when I remove the fuses of the front doors control modules. How to determine what is the problem. I replace the door modules with second hand ones and the situation is the same, there is again battery drain. So may be there is something else connected to the front doors controle modules.

Is there any fault codes related to door module?

No fault codes

The drain is jumping from 0.02 to 0.05, 0.09 or so for a second. May be other control modules in the doors. There is some logic to be the two mirrors control buttons in the driver's door because it is the only common thing between the two front doors. I do not know
