Please Help
I have a E class 270 Aventguard
It all began with a 1 malfunction electrical consumers.
I was advised to take the battery out a charge it.
I did so and everything was fine then i got a red sign saying battery/alternator
and then a sign which says visit work shop.
Any1 out there that knows what the problem can be.

This warning suggests that the battery is not getting charged.
depending on production date and model designation you need to replace either the alternator regulator (if available seperate) or the complete alternator.
