Thank you.

I don't know your car. I don't know what year it is.

I don't know what you are thinking, only what you are saying. If you want assistance, give me some details. Otherwise, use the search function and figure it out like the rest of us.

Right now, I'd say it wasn't the auxiliary battery and you are just throwing parts and money at the car because you won't take the time to put it on a Mercedes diagnostic system to, at the very least, eliminate some of the potential culprits. Alternator, voltage regulator, battery control module, main battery, K57/2 auxiliary battery relay...lots of culprits but only one is guilty.

Again, I don't know what you are thinking, only what you are saying.
