B8.5 battery charging voltage. I am using an AGM battery. I appreciate that the charging cycle is quite complicated, with regen coming into play under certain conditions, but I was wondering whether anyone knew how to reprogram the relevant module using VCDS to limit the maximum battery charging voltage to 14.4V i.e. the maximum voltage specified by the battery manufacturer (Exide). At present, the voltage can reach 14.8 V (which is much too high) before it drops into regen mode.
