2006 w221 320 cdi long
Hello,
could you please advise where is located the small aux battery?
I have watched YouTube videos and the small battery is under the steering wheel, but on the left-hand drive cars.
Have pulled the panels under the glove box and under the steering wheel, but could not find it...
Actually im not quite sure if the 2006 320 cdi long wheel base have small 1.2A battery.
Have replaced the main (starting) battery in the engine bay and the additional battery in the trunk.
Really appreciate your help!
Cheers

I don't think any have THREE! If you have the main one and the aux one in the boot....then that's it AFAIK.
