I think that is just a bit of a disclaimer - "Don't come complaining to us if you set fire to your wife's ID.3"

I imagine that is accurate. Out of interest when you use it to charge the ID.3 do you have to do anything or just plug and go?

Has anyone managed to charge an Opel Mokka-e with a Tesla UMC Gen2?
I took our spare gen2 UMC that has never been used, which I purchased from Tesla UK with a Schuko (EU plug) adapter.
Upon connecting the type 2 connector on the UMC to the Type 2 plug on the rented Opel Mokka-e, the car recognises it’s plugged in (small red indicator on drivers display lights up) and briefly (for a second or two only) flashes “charging rate” information, before almost immediately changing to “charging finished”.
The Tesla charger does not make the usual relay/contactor click that you’d expect after being plugged into the car. The lights on the charger stay green (no scrolling effect to say it’s charging - just steady on - no red to indicate a fault).
Normally the Mokka shows a green light in the charge port bay when charging, blue for delayed charging and white for ready - but it remains white. I don’t have another car to try it on, but the Mokka charges happily on a single phase wall charger (supplying ~6kW) and on a 22kW type 2 where it has been accepting about 14kW.
Have tried a couple of different outlets and at a different house. With and without extension cord. Same no luck.
Earth and neutral are connected inside the wall plug sockets here.
I’m pretty much at the end of what I can fathom might be causing it not to work unless there are some kind of comms between the car and charger that aren’t happening?
Any bright ideas?

It reads like you don't know if this UMC is working OK with a Tesla either. You definitely need to confirm that the UMC actually works properly with another EV (preferably a Tesla but at least to discover if the behaviour is the same with a a different car).
Thanks for the reply… you’re right that the next logical step is to test on another ev (preferably a Tesla).
Unfortunately testing it on a Tesla will probably have to wait ‘til we are somewhere we are a little more likely to find one with a friendly owner or we get home (we’re currently in the very north of Bulgaria where EVs are few and far between and Tesla appear non existent).
I’ll see who I might find around on our excursions and if they’d be a willing participant in experimenting.
This charger is brand new from Tesla and I haven’t ever used it on any car. I didn’t think to test it before leaving, which in hindsight wasn’t terribly smart - we flew to Bulgaria and rented a car. I brought our own charger with us thinking it a good idea to have one with us because the car rental only includes a type 2 - type 2 cable.
It sounds from nearly everything I’ve read that it *should* work.
I’m wondering if anyone:
…can in fact confirm that Tesla Gen2 UMCs does work with the Opel Mokka-e - and thereby eliminate a charger-car compatibility issue - which would point toward there being an issue with the charger;
…or confirm that this car and a Tesla charger don’t play nicely together, which might help others who read this in the future.
I’ll be sure to post an update when I can test it with another ev, or better yet, a Tesla.
UMC is not entirely type 2 connection as such.
When I had a failing AC converter, UMC was working fine while regular type 2 would trip immediately.
You firstly need to check if it works with Tesla. Only then you can make any assumptions
I would expect the gen2 UMC to work but obviously it doesn’t in this case. And no one here specifically know about the MokkaE… I’m not even sure what you gain from knowing whether it should or shouldn’t… you know that this one doesn’t already so you need alternative charging.
Further to my post above, and replies from Adopado and yessuz, this evening I managed to find a very kind Tesla owner in a neighbouring town who was happy to test my Gen2 UMC charger with his Tesla Model Y. It charged perfectly.
So the conclusion is that the Opel Mokka-e can NOT be charged with a Tesla Gen2 UMC

Thanks for raising this. We’re taking our newly acquired Mercedes EQE on a Spain / Portugal road trip this summer and was hoping to use our Tesla granny charger as a backup. I’m pleased to report it’s worked fine with the Merc. Phew - relief - as I was planning to charge where we are staying.Further to my post above, and replies from Adopado and yessuz, this evening I managed to find a very kind Tesla owner in a neighbouring town who was happy to test my Gen2 UMC charger with his Tesla Model Y.

Did you rule out the possibility of a dicky supply? If the Tesla was successful at a different location could that have played a part?Further to my post above, and replies from Adopado and yessuz, this evening I managed to find a very kind Tesla owner in a neighbouring town who was happy to test my Gen2 UMC charger with his Tesla Model Y.

I would add that you replace with a socket from a quality manufacturer, my default is 'MK' and would suggest you stay away from the cheap brands.
Spot on @Exy1 . Indeed I just bought 4 x 13 amp MK double sockets from B&Q - they are under £5 each.

I am currently experiencing the same issues.
We have borrowed a friend’s Kuga and cannot charge it with the UMC. Tested the UMC again afterwards on the Model 3 and it’s fine.
The Kuga charges from public stations no issue. It’s really just the UMC it doesn’t like.
Was there any further updates/workarounds? From the comments here, it appears to be a Ford specific issue not playing fair with the Tesla UMC.
Hints welcomed.
It's more likely to be a Tesla UMC issue not properly supporting other cars.
The original UMC1 that came with the Model S and Model X (the UMCs that supported 3 phase) could nuke a non Tesla because it did not implement the charging protocol correctly and split single phase current ove more than one of the 3 phase cables - the recipient non Tesla car was told one thing and got something else.
Tesla also have their own protocol they typically try and use before switching to the industry normal one.

Plenty of instances of people successfully using the UMC Gen2 (all within the past 4 years) to charge other EVs ... Gen 1 UMC is a completely different kettle of fish.

Tesla granny charger on a non-Tesla?
Please excuse my ignorance if this is a stupid question! My other half has just ordered a Seat Mii which apparently comes without a 13A charger. As it's a Type 2 charging connector would the Tesla 13A charger be OK to use with it? Or does the Tesla charger talk a proprietary protocol? As we...

Clear, but this seems to be a Ford specific issue, as mentioned.
I have a Gen 2 as that’s all the ever shipped with the Model 3s
Agreed. I was countering the suggestion that a non standard Tesla UMC protocol was the most likely culprit. At the end of the day if it doesn’t work it doesn’t work whichever end of the comms is at fault. However if multiple other brands work with the UMC there’s a fair chance that it’s the Ford that’s the problem.
