My e320 mercedes consumer electrical switch off.

eurotec :

Hi, this warning message will show if your consumer battery is bad.

eurotec :

You should have the battery tested and the charging system tested. Most likely this is just going to be a bad battery.

Customer:

This battery was replaced three month ago and this happen again

eurotec :

Ok, assuming the battery is still good you may have a fault with the alternator or charging circuit. The front battery can also cause the warning message to come on so it should be tested also.

Customer:

can this be a draining problem

eurotec :

Yes it can but if that were the case the message should go away after you drive the car. It could still be a bad front battery though.
