Hello

I have checked my battery using section 19 and wondered if any one could shed some light on my results? I have used the wiki and not found anything to explain them. I have had no faults related to the battery, I do have a glow plug code which I think requires plug replacement p0671 cyl 1 glow plug circuit. note I have just completed a 200mile drive so would expect the voltage to be higher, that said I have never been good with elects.
the battery says it’s a moll de mla 12v 520a 110Ah din 850a EN/SAE. Would the 44Ah result mean it’s going to need replacement soon?

It might be useful if we knew more about the car. If you've posted an Auto-Scan from it, please link to it. If you haven't posted one, please do.
