My "state of charge " on the MFD was showing 0% for some time, despite a few good runs. The stop start hadn't been working for weeks and the display screen said "Power Consumption High". I hadn't yet got a "low battery" warning but i sensed it wouldn't be long coming.
My car is just over 3 years old. I took the decision to replace with a Halfords (Yuasa) 096 AGM and they coded it too. Just about every single warning light came on when fitted, all but one disappeared upon driving, I had a persistent ACC Error afterwards but this has finally cleared now too.
