Hi Everest, I use two methods. 1. I use the obd to interrogate the BMS. This gives a variety of info, as you will know. It will check battery current state of charge, amount of current that can flow, actual battery capacity, total cell voltage, individual cell voltage, equalisation of each cell...

You do need an MG/professional diagnostics tool to access the cars radar learning modules. Aside from that I'm not sure any codes are needed. I've done this on several cars over the years without needing codes but of course it's perfectly possible MG need them. Never done this on an MG. It is a...

The later ones are fine even at high mileage. They have better BMS. Just as an addon Paulie, we have 5 EV's in the family including my ZS & the Leaf. We have an E-Niro with 103,000 on the clock & 94% SOH. An ID3 with 88,000 & 97% SOH, an id4 with 60,000 & 98% SOH. All NMC batteries. Two friends...

Just to reassure you Paulie, there are quite a few MK1 & 2 Leafs with much more than a 100k on the clock with their original batteries. Several owners on YT too with those cars. I am auto EE & mechanicals. You are right, most folks don't understand their batteries but frankly, they don't need...

Paulie, all lithium batteries use an upper & lower buffer. The figure the garage gives you is as good as you'll get & all you need. These buffers are accessible by the cars BMS but only when carrying out a full & proper equalisation charge to 100%. Throughout the life of the battery a small...

Yes, I have a print out with all the battery data on it.

It does depend on charging & equalisation habits too. You get a slightly lower figure but then after a couple of equalisation charges it can be better. That's why equalisation charging is so important. Also battery temperature is important when checking soh. It can also improves with a slightly...

That is the latest version. It has the secondary account settings.

I have the latest iSmart app. It does have the second account option.

The secondary account may need to log back in as any update to your iSmart app may log it out.

Just 6,000. No miles at all. Likely to be much more this year.

Why lazy or incompetent Paulie? Yes, all batteries deteriorated from new. But it's the buffer area that is doing that first & that won't if I'm lucky show up for quite some time. To assist this I do a full & proper equalisation at regular intervals which definitely slows degradation.

Thanks Alb. That's great.

The crucial step before doing anything else is to load the MG iSmart app onto the phone of the person who wants the secondary account. Next create a new account for them using their phone with their email address included. This can just be their name & email. Click register & the account will be...

The new cell pack will be calibrated to match the rest of the battery pack before rebuilding. Otherwise the battery long term integrity & range will be affected.

You might try disconnecting the 12v battery for a few minutes. That might clear the issue. Make sure you remove the negative lead not the red positive lead. If that doesn't do it a visit to your dealer is probably needed. Of course, I'm assuming the front bumper camera is clean & working too!

Just had my first service carried out on the ZS & everything is fine. My battery SOH is showing as 100% which of course is very pleasing & tbh I was expecting. My dongle showed this prior to the service. Out of interest I'm wondering the following; Firstly, just how many of us get a 100% SOH...

Remember, not all Tesla sites are open to all vehicles. The Tesla app, once configured, will only show the sites that are open to all vehicles. So that is your database. The closed sites just don't appear. So as long as your car has the Tesla upgrade it should work if you have the app configured...

As the motor runs in (beds in) the petrol engine seems to get smoother & smoother & more powerful. That was my experience of a brand new MG3 when I had one for 3 weeks last year. To start with there was some vibration from the petrol engine, but after 3 weeks the motor had loosened & was...

hmadsen is correct. Your car must interface with the MG mainframe computer at their headquarters. The computer will scan your cars entire system, offer R27 & then update the other computer modules on your car. There are 6 main computer modules that will update & upgrade after the R27 is...
