Some of the web post I see say two K57 relays, one in front and one in the rear.

In the end, the Aux Bat in the front is not charging just after starting like it should. I should see my meter go from ~12.5 to 14V just after start. Alt seems to be fine at 14.2V after start, and both bats are new (front and rear). The web pointed me to the AUX bat relay.

I have the Batt. message on the dash.

Have you had the fault codes read out?
