Hi, many thanks for your very clear description, and in particular for showing IID screens. There are many posts on many forums (fora?) saying that battery needs to be reset in BCM and CCF needs to be changed, you're the only one showing how - Great
ReplyDeleteI'm preparing to do similar change from non-AGM to AGM battery, except my old battery is already H8 size. Please do you recall how you "told" the car in CCF that the new battery was AGM? Or does it figure it out by itself? Regards, Alan
Glad you found this post useful, the only options I could find regarding battery type were under Car Config > BCM-Body Control > Battery Type.
DeleteOK. Many thanks
