AUX Battery location
I never thought the W204 C63 had an aux battery. Took my car into the stealership for recalls, they said I needed "both" main and aux batteries. Quoted $761 to install both... If there is an AUX battery on this car, I don't know where it is. Anyone have any insight on this?

No AUX battery that I'm aware of. Starting battery runs ~$200 from what I researched last week.

Never seen an Aux battery in a w204 c63, in other cars from around the same time it was under the fan shroud cover left side under the hood and newer W205 has one. Battery should be under 300 even from a dealer and like 10 minutes to change it.

I checked under that fan shroud. Nothing. I didn't think there was one anyways. I got a new battery for $180 with a black friday coupon. Took me 15 minutes... I swear I have the worst MB dealer on the planet.

I see no issue with naming the dealer who quoted this.
