Hi!

I have just bought and fitted a 120A AGM battery in my E61 LCI 530d.
Coded the CAS-module to a 105A AGM battery (largest AGM to select)

Used Inpa to register the new battery, and cleared the histogram.

But INPA reads it as a 81A battery in PM2 (see attached battery)

The VO code has "-A090".code for the battery, and that is the biggest as I know.
(Does not accept "-A105" og "-A110")

How do i get the car to know it has go a bigger battery?

 

Just a WAG, but maybe your INPA version is out of date, do you know what the battery size is supposed to be from the factory?
IOW are you supposed to have a120A battery instead of a 90 in the 530D?
Lastly if all else fails I would just not worry about it and live with the settings you got.
Battery will get charged with the settings you have and all is well is my guess.
