I just wont update...

Why not? Software updates are generally a good thing, fixes bugs, new features, etc. Sure, sometimes updates come with new bugs but generally after the update there are fewer bugs.

I edited the message, I meant to say "it" wont update. I tried many, many times, I never get it to show any newer version. it says I'm on 1.0.0 (13.1.32.2212081.1)

the car connects to the home Wifi

I have to bring to the dealer for a full upgrade via their tools, this atto 3 is still on 2022 version and wont update anymore. Only option is to bring it to the dealer, which I'm really lazy to do... maybe in 1 year for the next maintenance if I still have the car, or not...

Really strange you've never been able to do an OTA update. And what's stranger IMO based on that 13.1.32.2212081.1 software number (representing a 8 Dec 2022 software date) it's like your Atto software has never been updated....even the dealership hasn't updated it during the service/maintenance visits. Or maybe they did update during a past service visit but then downgraded to an earlier version on an ensuring visit for some reason (or by mistake).

I would definitely be asking (demanding) why the software/firmware hasn't been updating "especially not even being updated during service visits." When you do get your Atto software updated to the latest version you'll be lost for a week in trying to figure all the changes, where old settings/icons moved to, new apps, etc....etc....etc.

Question: did the dealership tell you that after X-years your car will no longer get software updates? Like where you said since your Atto is 3 years old it no longer gets updates. And this is not to be confused with the SIM only providing 2 years of 2GB/month mobile data....because even after 2 years the SIM still continues to use a small amount of data for basic/core vehicle communications to the BYD mothership. It's just non-core apps like Spotify, Youtube, Google Maps, etc., are not allowed data access after that 2 years of 2GB/month data allotment is expired.

V2.0.0 OTA being rolled out for BYD Seal owners here in Thailand according to FB groups, hasn’t dropped for me yet.

Currently on V 1.4.1 (2503) which dropped over a year ago while V2.0.0 dropped in uk and Europe several months ago and they are now up to V2.2.0.

From what I can tell it includes the UI update ( to make Home Screen similar to SL 7 ) , several improvements to cruise controls ( slowing on curves etc) and the usual bunch of enhancements.

The only negative I see reported is that the “ welcome seat” function doesn’t work if you use anything to allow rear passengers to travel without using seatbelts ( some would argue that this isn’t a negative ) as the car assumes that there are rear passengers so doesn’t move the driver seat back for “ fear of a pinch situation” ( BYD words not mine ).

But also means anyone using a car seat/booster in the rear will disengage the welcome seat function.

In theory this should only apply to the seat behind the driver but am not sure if moving car seat to seat behind front passenger and reinstates the welcome seat function, I don’t think it does .

On a slightly similar note: I find the notification for OTA( a red dot 🔴 on home screen currently ) slightly annoying as it doesn’t always appear.

For example, i have two outstanding language updates ( Cantonese and Mandarin I believe ) which pop up occasionally but always when i enter the car to go out and never when i am at home with time on my hands, as now, so remain undownloaded !

I cannot find these updates anywhere to download them and the notification screen shows “ no notifications “ until they reappear in a few days time when i am leaving the house and don’t have the time to download them !!

An actual OTA will do the opposite and appear constantly until you relent and allow the OTA download !!

Use the BYD Assistant app to see and download any language pack updates. See youtube below.

Yep. They never updated it when i bought to service. Neither I ever got the chance to update it via the car. I was never expecting any updates and I don't use Facebook often, Hehe.

Thanks for the suggestion. I might take to byd just that it's 50 km away.

And I'm enjoying the IM5 too much.

Man than car has some things that are very different!

• The car uses Km range instead of battery percentage, you can't just just have battery percentage on the screen. Only via multiple clicks. It's nowhere!

• You Start the car by pressing the brakes.

• Can't turn off car. You leave the car and it will shutdown eventually or, if you lock it or charge it.

What really put a smile is not the raw power, it's the rear wheel steering working. The turning radius is so impressive and changing lanes on highway is so cool then combined with the motor power. Damn!

Unfortunately this didn’t work for me, suspect the video is from a SL 7 ( or an updated Seal ) as i only get this upon clicking Voice Language and i know that there is an update for Mandarin and Cantonese available, i thought there were more languages than that or maybe i was thinking about the car’s language and not the BYD Assistant ?

So i guess i will have to wait until for the OTA to V 2.0.0 or if the notification to update the languages appears again which only happens every few days, maybe a week ? and invariably happens when i am on the way out !

Taken to starting the car every morning and during the day now.

Obviously this is not a biggie as my Mandarin/Cantonese language skills are nonexistent but i did think updating these might trigger the OTA in some way.

Have been seeing FB posts for about a week now about owners in Thailand receiving the OTA, but with each post numerous posters still waiting.

Will wait a few more days and maybe a trip to the dealer for me !

Maybe your language packs auto updated already.....and I'm little surprised your Seal shows so few installed "and un-installed/available" languages. The number available maybe has something to do with what countries the Seal is sold in.....I don't know.....just guessing.

Below is a snapshot from this morning of my Atto 3....languages installed (English, Thai, and Cantonese) and non-installed/available (all the other ones listed). And actually there is another half page of un-installed languages when I scroll down. If I remember right, when one of your "installed" languages has an update an update icon will appear....I think it appears in the same location as the Download icons shown. And of course you get a notification occasionally until the update is accomplished.

For the next few days I'm driving the Atto 3 and have my SL7 under a car cover right now....so I didn't check the SL7 to see (too lazy to take the car cover off) as to what it shows. I'll check in a few days once driving the SL7 again.

Yeah, maybe the English, Thai, Mandarin and Cantonese came pre-installed and these are the ones that are available for updates ( think i updated English and Thai previously but didn’t bother with Mandarin or Cantonese updates ) .

Am sure i have seen a longer list of languages available that i didn’t install, Malay in particular certainly rings a bell.

Anyway it does seem a little strange.

Notifications for updates to Mandarin and Cantonese have been popping up for a long time ( maybe a year ? ) so i doubt if they auto update .

Anyway, hopefully all will be revealed in the next few days. !

For those of you who own an Atto 3 and want a detailed manual on the car....like the dealership technicians go by....then go to below weblink and download the zip file...unzip the file and then use the "index.html" file to open the manual....you'll get below menu and then you can view various service manuals. Normally I don't download just any file from the internet but occasionally I do and of course do a virus checks during the process....it came back clean of any viruses. I stumbled across the file/manual when "googling" for such a free download manual. The Diagnostic and Service Manuals are most interesting "with down in the weeds technical data" like what temp your AirCon system should be reaching/blowing, info about HV battery like "cell balance," etc. The manual also show a "bunch" of other stuff like where components are, how to disassemble parts, etc. I've spent less than an hour viewing the manuals...but found some nice-to-know things...like what temp your A/C "should" be blowing if operating properly, HV battery pack cell balance specification, etc.

Weblink to manual(s) file download...then let it unzip...then start-up using index.html file.

https://workupload.com/file/rJ8HpQFL6MG

And below are a few snapshots from the manuals with some comments I've added.

Identifies the A/C vent output temperature of a properly performing A/C should be. I would recommend the temperature probe be inserted past the outlet vents...like around the length of your middle finger deep...and doing such in the shade. After the giving the system around 10 minutes to fully cool down with the temp value set to Low/18C and fan speed to 1 (one) check to see what temp you get...it should be in the 5-8C ballpark.

HV Battery "Cell" balance. A BYD HV battery pack is a bunch of blade battery cells placed side by side and connected in series to add up the cell voltage. Like in my Atto 3 Extended Range 60.48KWH battery it consists of 126 blade battery cells. The battery pack Battery Management System (BMS) monitors/measures the voltage of each and every one of those 126 individual battery cells. The voltage of all these individual cells must be very close in voltage value otherwise the the cell(s) with he lowest (weakest) voltage values negatively impact the overall capacity/health of the battery pack. The weakest cells become the driving factor in how healthy or unhealthy your battery pack is. If you ever used a OBD2 dongle with the CarScanner OBD app it will show a "cell balance" reading....that is, the voltage "difference" between the cell with the highest voltage and the cell with the lowest voltage. That voltage difference should not exceed 90 millivolts (0.09V) for a healthy battery pack. Well, actually it should be a lot less than 90mv for a "healthy" pack...it's just if it's "greater" than 90mv the Atto 3 Diagnostic Manual recommends several "equalization" charges be accomplished (i.e.., charge from below 10% SOC to 100% SOC) to see if that rebalances the cells...gets the cell balance to 90mv or less....if it don't the manual then recommends battery pack replacement. I've monitored by Atto 3 battery pack for years with a dongle/CarScannerPro...and my pack's cell balance at rest has always be around 6mv when at rest.

Based on all the posts here recently about how good the IM5 is, I started looking into the IM6, as I want a premium mid size long-range SUV (all are around 1.6M Baht). Two days ago, I test drove the Tesla Model Y L, was very impressed, but when I add up the price and insurance costs, (though it is a 6-seater) t seems way, way overpriced compared to the Chinese offerings (When you add color prices, and other stuff it comes out to 2.3m (700k more expensive at purchase) + 10 years of insurance 40k/yr more it comes out about 1.1M more expensive over 10 years. Zeekr 7x is good, but some reviews out of Australia and in Thailand of actual owners has been less than stellar. And, to top if off, Electric Viking test drove the IM6 for 1,000 kms and yesterday posted a video where he says the IM6 is better and he openly offered to swap straight across his 7x for anyone who had an IM6.

So, yesterday I test drove the IM6 and it was indeed impressive. I am interested in the long range model. Honestly, it drove somewhat like a Benz, and did indeed feel better than the Zeekr and anything else I've tested in that price range. However, I am not crazy about the design, and then as I viewed more Thai reviewers youtubes in China there is a minor change model out a couple months ago in China that resolves all the design issues I had. It's great. So, I will wait for the December motor show in Bangkok and hope they have this updated version then.

Part of my daily commute is 5 km of mountain curved roads. Beautiful views with foggy mountain tops all around you that makes driving the IM5 a pure pleasure

Indeed it would be wise to wait before a refreshed im6 comes out instead of buying now. Decembers motors show is coming.

The im5 came 1 after im6 and even thou they're the same car in a different body, the im5 had many upgrades , according to forums in China. Such as the rear wheel steering improvements and other tuning.

For me the first rims that came on im6 didn't look great, but the new rims on the IM5 are so much better.

The IM6 will certainly be updated soon i imagine.

One thing i would not rule out on a Tesla is the software and cruise control. The only reason the Tesla is a better buy even if it costs more is the software and cruise control. It just works great and is far ahead. Whereas the MG software and cruise control leaves out a lot to be desired. It's terrible actually, BYD has better software than MG.

If you truly value cruise control and a great software experience, only a Mercedes and Xpeng G6 are at the Tesla level in Thailand.

I think MG software is really far behind Xpeng, Zeekr and BYD.

for me i can live with the nuances of the im5 because the car is great to offset that.

The most pain is that it won't remember regen levels, but on the good side, you have option to totally disable it , some people may like that, but i prefer the light Regen level.

Yeap, when it comes to regen level setting I "much" prefer Standard vs High on my Atto 3 and SL7. High regen causes your head to lurch forward on deceleration (i.e., slows down too much/fast) and it makes keeping a safe distance between the vehicle in front of you "and behind you" harder which is critical in heavy and fast moving traffic. The High regen simply does not feel good to me (or my passengers....especially my primary Passenger Princess who is also my wife).

Now I know this may ruffle the feathers of those who subscribe to "one pedal" driving as the best way to drive, but when High regen is causing everyone's head in the car to lurch forward and probably does "not" add more energy back to the battery in comparison to Standard regen because the high regen lasts for a shorter time than the standard regen which in turn probably balances out the total power being regenerated back to the battery over the regen time period.

Say High regen generates 20KW over 3 seconds of quick deceleration that's a total of 60KW being feed back into the battery over that 3 second period...but if Standard regen generates 10KW over 6 seconds due to its slower deceleration effect that still results in 60KW being feed back into the battery over the total deceleration period. You still got 60KW going back into the battery for a short period without the head lurching and impact on keeping a safe distance between vehicles.

I remember a Youtube video where this guy who owned an Atto 3 in Australia who did a test on Standard and High regen setting for a full tank of electrons of his normal driving in his local area which was combo city and highway driving....took him about a week to empty each tank of electrons...go around 400km on each tank full. His conclusion based on the real word range he got "and" OBD2 data was when the dust settled the High and Standard regen generated the same total amount of regen energy over time. In such a case, using the regen setting that feels most comfortable and safe seems to be the better choice.....unless you belong to the Church of One Pedal Driving where using High regen is the 1st commandment. 😁

Almost left the MG today with one, color in stock. Hard to beat for 529k. If nephew agrees to buy our ZS before the end of the month, may get one before the price increase.

Entry level specs are nice. Larger interior area than our ZS. Start over with -0- on the odometer vs 65k, and 100% SOC, with tad more range, not that we need any.

And last car my wife will ever need with the warranty in place. Just something about the ZS that wins us over, and it's not logical, as Urban is a slight bit better on paper, even though basically, a lateral move, ZS to Urban.

The tech over 4 yrs really has improved. ~20% less battery, and they manage to squeeze a bit more range out of it. And offer a few bells & whistles that the ZS doesn't have.

Hehe. Not a typo, but it depends on models too. In general I think Byd has less bugs and issues. The MG Urban might have a better software since It’s newer. The IM5 is ok with a few bugs and annoyances at every single startup. But once past you get a really nice Wireless Apple/Android car play connection at the same time of Bluetooth connection. Two phones can be connected but only one can play. I’ve read that ACC is abominable terrible so I don’t bother to try.

It will never be as good as Tesla but for some people it’s acceptable. Like me.

That’s great, bro wise!

also safety is supposed to be much better as well, night time driving, and on heavy raining. You get new tires as well and more comfort for sure.

The other day, I really liked it when I sat on it and tried all seats. I noticed the driver have a very good visibility like the Honda Jazz used to be.

In the IM5 high regen is default on every start. So you need to change with a shortcut on that screen. 😅

I really don’t like high regen on the Byd. At least on the im5 it’s acceptable and not so hard and sudden. Light regen is super smooth and off is just like neutral, and the car coasts for very long maintaining speed, I think It’s not safe to have it off. It feels not right.

Yeap...basically "no" regen feels like an ICE vehicle because you "only" have mechanical brakes to stop the vehicle. Once a person gets use to driving an EV which utilizes regen braking "and" (if/when needed) mechanical brakes in being able to stop on a dime when driving any vehicle that is only using mechanical brakes it definitely gives a feeling of a " lot less braking ability."

When my wife first started driving the Atto after being use to the Toyota Fortuner the first thing she commented on was how much better the braking power was on the Atto.

Yes, I can see that for myself in the test drives , reviews and the self parking that the Tesla is clearly the best software. And yes, I do hear that the Xpeng G6 is the only Chinese car close to this level. I don't really use the cruise control and self driving that much but do care about the self parking (wife). Overall, the IM6 is quieter than the Tesla, and drives better than the 7x or Tesla in a euro-car BMW/Mercedes kind of way. Car-for-car, comparing the long range model Y, the all-in costs of that are around 2 mil, so again 400k more expensive than the IM6 or 7X LR. When you factor in insurance costs (I found out larger NMC batteries of 100kwh in all long range models) are more expensive than the LFP battery models and all the premium brands will be 40k+/yr for first class insurance. Again the Tesla will be on the highest side around 70/yr because of the aluminum body also plus the battery. So, assuming the Tesla Model Y is 30k more expensive per year in insurance that adds another 300k to the price difference, (10 years of use) so we are looking at the Tesla Model Y being really 700k more expensive than either the IM6 or 7x.

That's a steep price to pay for self-driving and better self-parking for the wife. I won't use either.

add clarity

For those of you considering like me using your EV as a temporary power bank for your home [V2H], this is the latest info I got with regards to proven compatibility with EV models on Thai roads.

The list is not static as more solar installations with a bidirectional DC charger are being tested in the field.

Note that these V2H solutions have not been certified or supported by any EV maker. To my knowledge only the V2H solutions provided by a few EV makers in the US, Japan and Europe falls under the EV warranty. If you worry about this, consider an out of warranty 2nd EV or use V2L.

But the highest strain to the system is not the EV, but the bidirectional DC charger. Due to higher temps it has a limited warranty period of 2-3 years.

Car-for-car, comparing the long range model Y, the all-in costs of that are around 2 mil, so again 400k more expensive than the IM6 or 7X LR. When you factor in insurance costs (I found out larger NMC batteries of 100kwh in all long range models) are more expensive than the LFP battery models and all the premium brands will be 40k+/yr for first class insurance. Again the Tesla will be on the highest side around 70/yr because of the aluminum body also plus the battery. So, assuming the Tesla Model Y is 30k more expensive per year in insurance that adds another 300k to the price difference, (10 years of use) so we are looking at the Tesla Model Y being really 700k more expensive than either the IM6 or 7x.

That's a steep price to pay for self-driving and better self-parking for the wife. I won't use either.

yes, I agree as well the Model Y is way too expensive to have in Thailand, imagine now if Tesla bought a Standard cheaper MY like the M3 at 1.1MB?

even if the MY standard were 1.2-1.3MB it would be selling very well.

have you looked at the 7X detailed review? https://www.headlightmag.com/2026-06-23-picture-specs-zeekr-7x-long-range-rwd/

the translation is good enough.

I noticed it comes with 19" instead of those hungry 20" on the other cars on the same league.

for me the car I really tried to get the wife to buy was the 7X, but she wanted the IM5 too badly. so I have an IM5 now. She doesnt like Tesla, so that's off the list.

I think it's an amazing car and value for what it offers. 800V, 100kW, big space, decent software, and super comfortable.

For those of you considering like me using your EV as a temporary power bank for your home [V2H], this is the latest info I got with regards to proven compatibility with EV models on Thai roads.

The list is not static as more solar installations with a bidirectional DC charger are being tested in the field.

Note that these V2H solutions have not been certified or supported by any EV maker. To my knowledge only the V2H solutions provided by a few EV makers in the US, Japan and Europe falls under the EV warranty. If you worry about this, consider an out of warranty 2nd EV or use V2L.

But the highest strain to the system is not the EV, but the bidirectional DC charger. Due to higher temps it has a limited warranty period of 2-3 years.

I could see ourselves using that maybe tonight, if having, as been raining almost non stop past few days, and solar at 57%, so only 27% or 5.4kWh before grid kicks in at 30% battery.

Could have been conservative and used fans instead of ACs today, or on internet with phone instead of laptop & 55" TV

Might use 2 or 3kWh tonight, and set us back 12 baht, if charged at all 🙄

If we pick up the Urban, that will give us near 100kWh of batteries if all full up. Can never have too many eletrons

I want to explore this V2H setup at some point when my new Garage+Solar setup is finished, Atto3 with 54kWh available and the IM5 with 100kWh, could be a nice power bank. I plan to have somewhere between 8-10kW with a 15kWh Deye battery inside my workshop room in the garage, it will have an aircon to keep the battery cool during the day.

Lately I've managed to avoid fast charge with the IM5 since it allows me to schedule charging, so I start charging 23:30 and by 7am before I leave home it's always between 70% and 80%, and here is my first report on the IM5 range, I usually do 120-180km a day here:

Battery SOC: start at 80% down to 47% (total 33% used)

Distance: 180km

Mode: highway 80% (100-130), city 20%

Usage: 5.45 km/kW or 183Wh/km.

Today I drove a bit spirited, I think I can do even better at 160Wh/km,

on the way back home, 28km trip, it used 13.9 kWh/100km, driving mostly 90-110 Km/h

The IM5 motor sound above 110-120km/h is so addictive! i must record one day.

I must do math different than you. I get 33% used quite a difference for your calculations. Or maybe I am too new to electric cars. ☺️

Yup, you need the buy-in of your wife or partner for any decision, and I understand why you chose the car you did. In my case, my wife loves both the Model Y L and Zeekr 7x. We just test-drove the YL a few days ago, and are going to re-test the 7x this Saturday. For me the calculation is the 10+ year reliability, surety, and usability of the car, and in that respect the Tesla wins hands-down over any relatively short history Chinese EV. My wife reads all the facebook groups of owners of all these cars and all the Chinese brands have more complaints, software glitches, crazy wait times for parts and other things. In terms of parts, this might be the deciding factor. I am very concerned at all the Chinese brands and how they do model changes, refreshes, every year and half (vs 5-6 years for Japanese & similar for Tesla). For any Chinese car, this means the model you buy today will be outdated severely in five years, and already difficult parts availability will become impossible in 5-10 years (and Chinese EVs might be on the road in Thailand held together by duct tape). And, this is reflected in the recent news showing Chinese auto buyers change EVs every one year and eight months on average as technology and changes are so rapid.

I know the Chinese have tried to address this concern by making some models that they consider to be export market models only (like the BYD Sealion 7) and I suppose they will have fewer changes and therefore parts might be available longer, but the China is not a closed place and buyers will soon realize they have an outdated car as they see the new models in China only. Tesla has solved this by design and software perfection. They see no need to change design often, and OTA software updates are mostly flawless. The Chinese have not got this down yet, as can be seen by complaints on the Zeekr facebook groups and youtube in Thailand and Australia by the recent software updates.

So, overall, Tesla might still be the most intelligent choice, even though much more expensive.

in many ways, i have to agree with you. when it comes to software, energy efficiency, and driving dynamics, tesla is definitely among the very best ...

however, i also think there are other factors worth considering. to me, the design has become rather dated and no longer attractive. the interior feels very poor and so basic, with little sense of premium quality, and many features cost extra. there's also only one service center in bangkok, which isn't exactly convenient ... for someone like me living in nakhon nowhere ...

and then there's elon musk himself. his unpredictable behavior and some of his controversial political views are factors i (for myself) would also consider before making such an expensive purchase ...

Yes, those are things to consider, but the design issue and interior are subjective, however I agree with you on the service issue for those living in Nakhon nowhere. Last week, Tesla just opened a new showroom in Korat (flooded with customers and test drivers), and announced they will open a service center too early next year. But Tesla needs almost no service, not even yearly as most Chinese EVs do. But, when one goes down, sure there is a long wait to get it fixed. All the Chinese brands are opening showrooms and services centers like mad country-wide.

As I try to comb the internet for stories of Tesla owners for 10 years or more, only Model 3 has been around that long introduced in 2016, and results are good but mixed also. So, perhaps the impression that Tesla is more usable over longer term is not justified either. Maybe any Chinese EV brand is just as usable longer term...nobody knows yet.
