Hi, Today we took the Leaf down to Brisbane Moorooka Nissan for its 10 000 km/6 month service, which happily was a freebie, as it was included in the sale deal. The service took longer than expected, as they ran an updated software program, something to do with recharging. I haven't had the chance to see whether it makes a difference, and the service person couldn't tell me much about it. Has anyone else had a software update? I didn't think that they'd sent any through to Australia.
We also stopped at Tritium to recharge on the way down, and had a lovely chat to the guys there. One of them suggested using suggestion boxes/feedback forms at shopping centres/hotels etc. to request EV charging, so that businesses get a sense of there being some demand. The Tritium people get so frustrated trying to get some Tritiums fast chargers installed in Qld, when they've sold so many to the US and NZ. Also had a quick peek at the factory through the glass wall in the office, looked quite cool. Always good to see some Australian manufacturing.

That sounds suspiciously like they were making an excuse to take their time or to give an impression they did more than just kick the tyres.
That's great you got to visit Tritium. Hope to see one in the metal one day!

Sounds like the P3227 software update has finally found its way to our part of the world... Think you would need Leaf Spy readings before and after to see any difference.

Had my LEAF serviced last week and had the software update too. I asked the service person what it included but he didn't know! Driving the car I can't notice any differences.

It's really nice to know we're not forgotten and they're actually looking after us with updates, even if it took a few years. Can I trouble one of you guys to go into the diagnostic menu and see if the version numbers have changed? Below are the steps to enter the menu and attached are photos of what the original versions are. Power on the vehicle Power off the audio Press the MAP button 3x Press the Audio Power button 2x Press the MAP button 1x Thanks! Attachments:

Hmmm. Not bad. That article is only dated June 2013. Less than three years to reach us. Bring on the 2012 LEAFs.

Hi Feng. I went into the diagnostics menu. The version numbers are the same as in your screen shots. Not sure what that means about the upgrade.

Getting the car serviced at Moorooka Nissan this morning and the work up sheet had mention of the ?P3227 'recall'. I asked about it and he seemed to think it was a switch so lets see what they've got to say this afternoon....

Hi Feng. I went into the diagnostics menu. The version numbers are the same as in your screen shots. Not sure what that means about the upgrade. I'm not absolutely sure that it's listed in those pages. I read the P3227 update reduces your brake regeneration and increases the apparent range by about 8km by taking out of the bottom end reserve. They probably did this to appease early adopters complaining about premature loss. The reduction in regen might also improve battery life since you're not pumping 30kW into the battery every time you stop. I have mixed feelings about wanting it installed now.

If that is the case, I definitely don't want the upgrade. My 2012 Leaf still have 20% SoC (Leaf Spy) when the Guess-O-Meter said 15km left. Not sure whether the previous owner did an upgrade or not, but this seems reasonable to me (to tell user the bottom 15-ish% is not usable). Oh, regarding the limitation of regen braking, that is even sillier! Why not remove the quick charger alltogether? . Quick 30kW charging here and there will not hurt the battery (if QC is OK-ish, then 30kW won't hurt --> avt.inel.gov/pdf/prog_info/SAEHybridSymposium2014.pdf). That over caution is just getting silly! Thanks for the info Feng!

Went to pick the car up this afternoon and the receipt stated the "update was not needed for this model". Weird.

Just had our 20,000km service done - $239.64 here in Adelaide curious how that compares. They said they did do a software update which is listed as ZE0 REPROG.OF OBC & LBC S/WARE. The battery is still 12 bars and all 5 stars which is good. I can't say I've noticed anything in driving range or braking. Also I've recently changed to using drive rather than eco as I prefer the responsiveness which didn't seem to affect range that was noticeble. The GOM is perhaps behaving a bit differently but we don't pay much attention to it as we tend to plug in when its sunny for a few hours every second day to use our solar panels. I'll have to try and bring up the diagnostic screen to see if its any different to Feng's.
Car seems great to me still but my wife drives it most and I'm stuck on a 50cc scooter breathing in the horrible ICE car fumes! The service centre person also thought the Leaf is a great car and said they still had lots of the 2012 models to sell and were disappointed that Nissan aren't pushing harder to sell them.

My car is having a 20k service now. They said they will do a software update on the car.

My husband says that what is on our screen is the same as what is on your screenshots. I wish that they'd been able to tell us more at Nissan about what the update details were, other than that it had to do with the battery.

My dealer told me they updated the software on the battery. Given their knowledge on the car, I am not sure their words are reliable.

David who used to be on the forum had his car serviced last week and said his brake regeneration feels noticeably different after the update. If it means making them more predictable (see my other post about grabby brakes) then I'll enjoy the peace of mind when it's done.

I would say the fluid was replaced, that makes the grabbiness go away for a while.

They are updating the software on my Leaf right now. If it improves the GOM that would be great, but limiting regen to get better battery life? Not sure if I want that.

Have we worked out yet if there's a way of determining whether the software upgrade has been done or not? Looks like the factory menu check as above doesn't reveal it.

The firmware is N-P3227, it fixes a corner case where the battery reaches 100%, but the charger does not disengage.
HV Battery
293A0-3NA0C --> 293A0-3NA0D
Charger/PD Module
296A0-3NA5A --> 296A0-3NA7A

Thanks for that.
Where abouts do I see those codes displayed?

I think you need an OBII device and query the units. Not all oz leafs are the same. I have noticed 2013/2014 complianced models has a min temp of 18, where my 2012 is 16. And the mode button is in a different place. So might be an updated 2012, or maybe a different batch?

I had the P3227 update yesterday!! Excellent update. My battery capacity was at 78.76% and 52.15Ah and after a 100% charge I would only have 16.6kwh of usable battery and GOM of 98km After the update, I now show 87.88% capacity and 57.11Ah and after a 100% charge it shows 19.2Kwh of battery and a huge 139km on the GOM. LEAF spy showed an extra 2566wh was put into the battery!! That's a REAL 18 km.

I still only have 10 capacity bars but if it stays at 87% I might get a bar back

After a 100% charge LEAF spy shows 18kWh and 52Ah which is considerably down on your numbers.
