Saw the following article here (thanks to EFF11 For the info) and below is the detail of how to code the change
From the Gateway (19) select adaption and you will get the following drop down list.
Select the Battery adaptation option
From the Battery Adaption Screen you can now change the following values
Rated battery capacity, Battery manufacturer, Battery serial number and Battery technology to match the battery you have fitted.
All of the these values can be populated from a drop down list the only one that has an option list is the Battery technology where you select the value you require.
There are two types of battery used on VAG cars.
Enhanced Flooded (EFB) are essentially standard batteries manufactured to much higher standards. They have twice the endurance of standard liquid filled batteries and are fitted to vehicles with Stop/Start.
Absorbent Glass Mat (AGM) batteries have three times the endurance of standard batteries and are fitted to higher specification cars with higher electrical loads. In these batteries the liquid is absorbed by a framework of glass mats.
You can use an AGM battery instead of an EFB one, but at much higher cost.
These modern batteries required different charging cycles from standard batteries. If you buy a decent battery charger you will have options to charge a standard battery or a smart battery.
This is the reason why the car's battery management system needs to know what kind of battery you have. If you change a battery for one with an identical specification from a different manufacturer you may not see any error codes and it may charge correctly.. If you change to a different battery without recoding, it may not charge correctly, even if you don't see fault codes, and that may affect battery life.
