I just remembered something else now.

At one point soon after I bought the car, I did some coding with NCSExpert. In that occasion I dumped the FSW_PSW file for all the modules and kept a backup of the original stuff.

As I was doing research on how to code the AGM battery, I remember taking a look at the FSW_PSW for the CAS (the or one of the module where the type of battery is registered) and I confirmed that my car had a wet cell battery registered (90Ah, if I recall correctly).

The line in the CAS FSW_PSW file is called KLASSE_BATTERIE and among the acceptable parameters there's a set where the Ah rating is followed by "_AGM" signaling it is a dry cell battery.

I never ended up doing it because I couldn't come to a definite conclusion on whether or not you just change the VO, the CAS FSW_PSW, both or something else... So I read people were fine with the regular wet cell batteries and put it to rest...
