I have received confirmation from Tesla Support that "there is a known characteristic with vehicle software 2023.20 or newer that is causing UMC updates to fail. This is currently being investigated by our tech/ engineering and we are hoping for this to be fixed via a future firmware update"Have received my Tesla accessories order with my new UMC
Confirming both my tails say 10A and 15A. Once I get my electrical outlet sorted at the house Ill clamp meter it + what the Tesla internal charge current is showing on the display
I am using the UMC for now, and would really like it to deliver the full 10A, and for the car to talk to my Powerwall and only draw from my excess solar production.
Mine still hasn't updated. I've done a few charges now and leave it plugged in afterwards.I have received confirmation from Tesla Support that "there is a known characteristic with vehicle software 2023.20 or newer that is causing UMC updates to fail.

Tesla have confirmed that it won't update until they fix something in the car firmware. They don't have a timeframe for that to happen.Mine still hasn't updated. I've done a few charges now and leave it plugged in afterwards.
I definitely have the 10 and 15 tails (I checked the minuscule print).
Where did you buy the 10A/15A tails? The Tesla website (https://shop.tesla.com/en_au/product/mobile-connector) shows me:I was just mentioning a limitation that people in Queensland may not be aware of. It is easy to read all the online information, buy a wall charger and have it installed in your single-phase supply, only to find you only get 4.8kW instead of the 7kW you were expecting.
It is useful to know both the specifications of the equipment or vehicle and how they work in the real world.
It is interesting that the Tesla manual shows 8A and 12A for Australia, even though their site and New Owners Manual showed 10A and 15A as recently as about 6 weeks ago.
I initially received a UMC with 8A and 12A tails. After I pointed out the advertising of 10A and 15A, Tesla replaced it (it took them three tries to actually send it, though!). I now have a UMC with 10A/15A tails, but the firmware has not updated despite following all the standard advice. A 10A GPO gives me 8A into the car.
I'm in the same boat. Recently purchased UMC and it came with the 10A and 15A tails. I tried a couple of times to get it to update but gave up.Mine still hasn't updated. I've done a few charges now and leave it plugged in afterwards.

I bought from the Tesla shop. I dealt with Sales Support. I pointed out the multiple places where they advertise that the UMC kit charges at 10A and 15A. It was a really long process, so I didn't have the UMC until after my car was delivered. I am now just waiting for them to fix the firmware.Where did you buy the 10A/15A tails?

But here: Mobile Connector shows 10A and 15A. I've bought a UMC only few weeks ago and it is only charging with 8A at the moment.
- 1x Mobile Connector
- 1x 8A Adaptor
- 1x 12A Adaptor
I will head back and check the tail's label to see if it is 8A or 10A. Did you contact Tesla via the website support or from the shop?
Thanks, I've got the 10A/15A tails for the UMC I ordered a few weeks ago. Yeah, just have to wait for them to fix the firmware.I bought from the Tesla shop. I dealt with Sales Support.

I have a “European” 32A 3-pin tail, so I can use my Tesla UMC with the wall socket I had installed for my Porsche charger (when my son brings an EV home or someone is visiting and my Tesla wall connector is already in use). This is the big round blue one, which is different from the Australian one AFAIK.Anyone bought 32A 3 pin tails?
European” 32A 3-pin tail
It's normally recommended to buy a 32A 5 pin tail and install a 5 pin socket at home, even if you only have single phase.Anyone bought 32A 3 pin tails?
Because some sparkies are "uncomfortable" with it, but only because they haven't seen/done it before, not because there's any real issue with it.The grey zone is installing a 32A-5pin plug on a single phase system.

Three phase industrial sockets should not be used for single phase industrial socket situations. Sparkies are rightly uncomfortable and should not do it.
