4.0TDI Battery
 

I am having some issues with losing settings when powered off.
When I turn the key on in the morning the MMI language is at the default German. The battery condition is showing around 10% on the car settings,
yet there seems to be plenty of life to crank the engine, starting is not a problem.
There is a battery in the boot on the right hand side. This measures around 11.5 volts. Is this the only battery or is there another battery somewhere?

No other battery... Have you updated the MMI to the latest version?

Can't remember if this was a known bug, or if it was a fault, but I do recall seeing a similar issue before somewhere.

How do I update the MMI version?

You need to get hold of the disks.. take a look at this thread for where you might find them..
