Decided to give the ND a run as she has been standing immobile in the garage for several weeks since her Service.

She started immediately although the sluggish starter indicated a low battery charge. The i-stop light then proceeded to blink continuously so I gave her a 30 mile run hoping that a fully re-charged battery would solve the problem.

Unfortunately she progressed to a full blooded warning message "Battery Management Malfunction" so she is now booked into NortonWay Mazda for investigation next Monday.

I do hope that I won't be competing with Kev for owning the most problem afflicted ND !

You then throw in a smart alternator and it gets even more confusing, no idea whether the NDs alternator is smart or traditional though.

Yes, I believe that my 2019 ND does have a smart alternator too, all part of the "Green" package to improve consumption and lower emissions.

On the plus side I understand that my 2.0 ND is in a lower VED band than the earlier lower bhp 2.0 NDs because of my lower emissions.

I think all petrol cars registered from 2017 on are now £150 a year to tax, except those with an original cost of £40k+ where there is an additional amount to pay on top. Fortunately, new MX5s have not reached this price point yet!

This is not so good if you own a small eco friendly car, where a 2016 car would be £20 / 30 a year to tax, and a 2017 onwards is £150, but is good news if you own a high performance car :nod: (not sure whether a 2 litre MX5 would be classed as high performance?

When the pcp ended on the wife's last Mazda 2 1.5 (£30) the new models road tax went up to £150.....

Hence we bought the 2.0 CX-3, at the same rate.

It could be a corroded battery since it sits in your garage for several weeks or worst, you have a bad alternator problem. I found an article on the YOUCANIC website about this issue, and it helps me a lot with my repairs.

Wouldn't be surprised if that battery has moved on by now, it was 2.5 years ago after all!
