I tried that in the CCf,and it wouldn't go to AGM,is yours definitely in AGM?
Tim,and others have told me it can't be done,with the D4 2.7.
He also recently said on here D4 2.7l has same charging system as D3.
I am 99% sure my OEM battery was not AGM,as LR said when they replaced it under warranty, the new one is now AGM,and will last longer.
Have you seen yours charge at higher than 14.0V?
The 3.0l will charge higher,14.8,etc,it has a BMS designed for AGM.
