W211 E280 4Matic
Battery "Visit Workshop"

Mercedes W211 4Matic 280cdi

Got a problem with the battery system. The diagnostic tool is showing the code "Check control module N82 or fault in CAN communication with control module A1".
I have replaced both batteries, AUX-battery-relay, and Control module N82, but the code is still showing as current.
Where do I go from here? The alternator is charging 14,2V and none of the batteries goes flat. Anybody knows what the A1 control module is?

Thanks.

A1 is the instrument cluster.
