E63 W211 Auxiliary Battery
Hi, I have a battery warning on my dash board, i believe it is the auxiliary battery that is going down... I can't find the location, does anyone know where it is located?
Thanks!
Thanks!

No, you don't have the aux battery. It was removed from the w211 along with SBC brakes for the '07 model year refresh. On earlier w211 cars it lived under the cabin air filter along the passenger side of the firewall under hood. You should be able to see an empty space there on your car.

It is under the Steering column cover, over the pedals.
The battery you need is :12V 1.2A...it is TINY. I changed one 2 years ago for less than $10 and it is working fine.
