Afternoon. I’d be grateful for your views on the following. The main battery failed yesterday and I’ve just replaced it with a Yuasa battery. The red battery failure light now no longer illuminated and a voltmeter says 12.7V. So all seemed fine so I reset the BMS using my GAP BT tool. However, the Eco stop/start yellow light on the dash to say that it’s disabled is now illuminated. Is this usual following a BMS reset, or will I need to replace the smaller stop/start battery as well? Both batteries original from when it left the factory in 2016. Kind regards, Peter.

I would suggest replacing the start-stop battery as well. It takes a while for the BMS to recalibrate after reset. After this Start-Stop should be available. It was the same when I replaced both batteries last year.

Perhaps just coincidence.
Your batteries have done well to last this long. The eco stop/start not availabile amber light is most usually an indication that stop/ start battery needs replacing. Replacements are around £40. Search on the forum. Original LR batteries are £130 ish, but exactly same with LR label much cheaper as stated.
My non LR labelled battery ( which is active original battery less label has lasted almost 7 years. ( Thats jinxed it!) Gary

My June 2015 ( model year 2016) uses an exide EK151. Try a search for that online for best price if you are going to replace. Gary

Thanks. I’ll replace the stop start battery too. Kind regards, Peter.
