BYD Seal

Are you going from 2403 direct to 2307 or via 2310?

Do you have a screenshot of the error message?
Typically if it's a config or setup issue the downgrade fails immediately - unusual for it to kick off and then fail later.

You mentioned verification failure, does your car have mobile data/ wifi enabled?

It was the USB that was the problem. Used 4gb USB, big enough for the download but think need more spave for it to work. Was able to downgrade, sideload and update to 2403 withoit issues on larger USB.

It depends needs and wants. Seal RWD comes with 6 year/150k general warranty (4years/80k with M3), 8 year/200k battery/drive unit warranty (160k with M3 RWD). Parking sensors, 85km more range (as per ev-database), 360 camera, wireless apple carplay, wired android auto, rear cross traffic alert, rain sensor, stalks, better blind spot warning implementation, slightly quicker acceleration, BYD doesn't have the constant bingbongs from 'autopilot'/'autosteer' engagement/disengagement, better thermally insulated panoramic sunroof, easier access isofix points, no phantom breaking from BYD's version of 'autopilot', vehicle to load, no dysfunctional wipers, more rear passenger space,

Seal has a more premium interior; sound system is probably par with M3 RWD but definitely nowhere near M3LR.

M3 offers Matrix lights, One-pedal-driving, Sentry (Might be coming soon to Seal), better app at present, ranger service, more storage space, supercharging network isn't a pro anymore since they opened all chargers apart from Sandyford.

If you compare cost per kilometre of range, the Seal is actually better value: M3 RWD €38,607, Seal RWD €45,986
M3RWD costs €93 per kilometre of range (415km average as per ev-database)
BYD Seal RWD costs €92 per Kilometre of range(500km average as per ev-database)

Sorry to nitpick but android auto has been wireless since the car was launched, apple carplay was wired until 2403 update (which isn't yet OTA), since 2403 apple carplay is also now wireless.

I don't believe it's misleading. Cost per kWh of battery is overall lower with Seal, but also range per € is better than M3.

Seal RWD: 45,986/82.5 = €557 per kWh
Model 3 RWD: 38,607/60 = €643 per kWh

I mean yeah, if you're looking purely at efficiency, M3 is the best but still get less range per €.

M3 RWD: 415/57.5 = 7.22 km/kWh
Seal RWD: 500/82.5 = 6.06 km/kWh

EV-Database headline range is just an average between the worst and best efficiency. Both Seal and M3 can average higher or lower efficiency depending on many variables. M3's can average worse efficiency than Ev-database's average estimate. I'm not cherry picking, I'm using data from a database that's reputable and regularly referred to on various forums.

indeed, but as @eagerv said, most colour options are free, same with interior.

Thus considering all of that, including extra warranty, I think the Seal represents the best overall value.

Cost difference to run afterwards is peanuts really, anyone who can afford a a new M3 or Seal wouldn't notice it.

Your brother must have a heavy right foot Gumbo. I am getting 20.2 kwh/100 km from my awd

Anyone else on 2403 getting the "Cap is not closed

" message every time you start the car?
Goes away after a few seconds, so not a major issue but seems like a bug.

I have 2403 and I dont get this message. Have you checked the charging port door. I think that is what is referred to as the "cap". can become an issue if you have installed an aftermarket seal on the charge door according to other FB forums

Safer to keep in eco then!😀😀😀

In my experience awd is still very quick even in eco
