Hello, could you help indicate the location of the little auxiliary battery?
I have seen YouTube videos indicating that the little battery is located under the steering wheel, applicable to left-hand drive vehicles.

I have removed the panels behind the glove compartment and the steering wheel, but was unable to locate anything.
I am uncertain if the 2006 320 CDI extended wheelbase is equipped with a little 1.2A battery.
Replaced the primary (starting) battery in the engine compartment and the supplementary battery in the trunk.
I really appreciate your assistance.

Thank you for your response.
I have seen on YouTube that all vehicles are left-hand drive.


I have removed the trays behind the steering wheel and under the glove compartment, but was unable to locate it.
