Dealship wants to charge for "Battery calibration"?
So I was having some module communication issues with my 2016 c300. I ended up having to take it to the dealership. They fixed the communication problem, but the's telling me that the battery which is only 3 weeks old is not holding a charge and needs to be replaced. They want to charge $650 to replace the battery and perform a "battery calibration".
Has anyone ever heard of this? This sounds super scammy to me.

On your way out, tell the dealer to go promptly Frakk themselves and go somewhere else, hopefully an indy shop or someplace that won't **** you straight to your face.

The "calibration" is not 100% BS, but in no way absolutely necessary.
On more modern MB’s there is a procedure when replacing the starter battery that requires informing the front SAM module that the battery has been replaced. You can do this with more advanced scan tools. I personally used a Xentry setup.
To do a “proper” battery replacement, you need to do this. However, it is not strictly necessary, and the car will obviously still run. To my knowledge, it alters the charging rate of the battery as it ages, and a reset reinitializes this. So, a new battery being charged as if it’s an old battery will wear out faster.
That being said, $650 for a battery is ridiculous. I just went with the Duralast platinum for $250 and called it a day.

Now they're telling me it's no good. I'm going to decline the battery from them and have autozone replace it under warranty if it actually is bad.

No - not for the hybrid. It's a standard procedure when replacing the starter battery on any modern Benz. Nothing "wrong" will happen if you replace the battery without performing the reset. No codes, no problems, etc. If you don't do the procedure, it will just overcharge your new battery (the charging circuitry will charge the new one as if it were the old one), prematurely wearing it out.
