Moin My V60 D3/D4 with start/stop from 2012 requires a new battery because the start/stop no longer works. Message in Sensus says that the electrical system is to blame. I have already replaced the small support battery under the wind course. Nevertheless, no improvement. When it was still a bit warmer it was still going on. Therefore I think that the main battery has to be replaced. Now I read that it has to be an AGM/VRLA because of the start/stop system. On the Internet I also find EFB B atterien which are supposed to be able to start/stop?! Can you trust it? It’s at least 30€ cheaper I don’t want to save the money but if you can save and still do everything right, why not? Have links to my selection here on eBay: EFB Battery AGM/VRLA Battery Which one is the right one or better? Greeting, René
