Call another dealer with your VIN and ask them. They should be able to tell you whether the update has been performed on your car.

Like Leftiebiker said the only way is if it has had the update.

But don't do what Goldbrick said...

Nissan is not Tesla... Their update system is totally manual and totally susceptible to human error. If some garage tried to apply the update in the past, before you bought it, but they did not follow the procedure correctly, the update was not uploaded to the car, but the mechanic didn't realise and ticked the box on the Nissan database to say that the job had been completed, then when the dealership enters the vin into that database it says the update is not required.

We assume the car as manufactured is eligible. So use leafspypro to check the ECU version numbers and screen grab to so show the garage (they can't do that).

Then show them the tech update paperwork which I have posted somewhere on this forum which refers to the different versions of software on which it applies.

If you are sure the software version shown is the non-updated version then insist that they ignore their database and connect to the car to apply the update.

But incidentally if you have all the bars showing on the dashboard, I expect you have indeed had the update. Post your leafspy software versions screen grab here. And we'll take a look.

Tom.

August update. 302 GID's 66.02 AH, SOH=83.07%, Hx=59.70%, 80550 total mi. 35629 mi on new battery. 22 DCFC and 702 l2 charges on the new battery. Even though I'm driving less, the battery is still deteriorating fairly rapidly in the hot weather. I lost another 4 GID's this month despite only driving about 750 miles. It's not as bad as the old battery in hot weather but it still shows up as higher losses during hot weather. As a comparison, after 25 months, the old battery was down to 68% vs 83% for the new one. I can probably get another year out of this battery before it becomes a real problem to drive. If the battery continues to fail at this rate and my driving continues to be light, I might manage to get a new battery before I hit 100K. It seems more likely that I hit 100K at about 70% SOH and no new battery for me.

Sept 1 update. 300 GID's, SOH=82.60%, Hx=58.93%. 81286 total miles, 36357 miles on new battery, 136 L3 total, 22 on new battery, 1595 l2 total, 721 on new battery. I'm driving a lot less now so wear and tear on the battery is less but it's still losing power at about the same rate per mile as before. It still looks like I won't hit the 4 bar down mark before the 100K warranty limit. At the current rate, I'll get 70K out of this battery before it hits 8 bars. That would put me at about 115000 miles overall. I'll probably trade it in sometime next year. Tesla is in the lead as a replacement but I'd like to look at the ID4 before I make up my mind. State and Federal tax credits on the ID4 that I don't get with a Tesla could make a difference. If Congress were to extend the federal credit to Tesla as well, that would make a big difference as well.

Hey John, and anyone else around.

I just left mine plugged in for a couple of days so that it could do any balancing that it fancied, came back to it and found a totally unbalanced battery showing horrible stats!

299 GID's, SOH=82.20%, Hx=58.98%. 62,800kms (39022miles), 39 QC, 1787 l2.

So I've had it 6 months, done 8000kms (5000miles) and seem to have lost 3% battery health (although the figures do jump about somewhat).

If that were to continue then I could do another 43,000kms (27,000miles) before arriving at 66% which I think is about when the fourth bar might go to paradise. This would take me to 105,808kms (66,000miles) still well inside warranty. On the timeframe mesure, it looks like 32.25 months or 2 years 8.25 months which would take me to about the middle of May 2023... and the warranty expires end of December 2023. So that is quite tight.

Specifically I believe the battery health has to remain below 66.25% for a full month before the fourth bar will go, and given how the measurements vary I think it could be touch and go, especially if degradation slows though the winter months.

Oh, and just my two cents worth; please don't reward VW for being the biggest fattest liars in the world, on an issue that actually concerns us all directly, by buying an electric car from them. They clearly don't care about saving the world, so they should be the first to suffer the consequences!!

I am stunned on a daily basis how many brand new VWs I see driving about here (France), its not like they're any better than any other of mundane brand offerings of the moment, but nobody cares, not a jot. The caché associated with owning a VW doesn't seem to have been affected in the slightest, unbelievable. And their perceived market is upmarket educated yuppies with children or indeed grandchildren... the kind of people who are supposed to think before they act, not try to go one up on the family chevy next door. Its a sad world.

See you next month, if we're still here.

Unlike some smaller EVs, when you leave a Leaf or other electric car plugged in, it will charge to 100%, doing any balancing while nearing 100%, then shut down. Unless you have a charge timer set to restart charging every day, it will not do any more charging OR balancing. Many Leafs will, in fact, drain their 12 volt accessory batteries if left plugged in for days, because they don't charge those batteries while plugged in and not charging, but they do draw power from them to periodically verify that the charging cable is connected. I suggest that you not do that again, and that you take a long drive with the climate control on low, or just leave it in Ready mode for an hour, also with climate control on low. You can also top off the 12 volt battery using an external charger.

The amount of balancing that the Leaf BMS can do is fairly limited.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Now that you have discovered the folly AKA top end balancing, hoping you have learned your lesson. Treat your new battery kindly and remember; just because you can doesnt mean you should charge to 100% SOC. Doing so only when you need it only pushes usability farther up the calendar.

Thanks Leftiebiker for that. Yes, I am aware of the 12v battery woes of others, but mine is just fine, is the original and still shows good capacity... Unlike the lithium ion one under the floor!

I know the balancing is limited, but I have seen the battery perfectly balanced previously, it's more like it didn't bother doing a balance at all, which is annoying as I don't often take it to full, shame to east the occasion that's all.

Dave, I don't have a new battery, John does. I am gentle with my old one, as I mentioned above it is annoying that the balance has not been done as I very rarely take it to 100. But one does have to be able to use the damn thing, so it has to get charged.
