The reason why I think this is a software bug is that every manually started charge does 32A no problem.There have been enough reports of this that I wonder if it is a software bug ...
... alternatively the huge influx of M3 in UK might be generating significant numbers of "real" scenarios.
Similarly more "tripped the whole house" reports, where a single device being unplugged then fixed the problem - so very slight earth leakage or somesuch, exacerbated when car was charging. My M3 did that at a friend's house, ran an extension over to their neighbours and no problem there.
If it were me I would most definitely want to find-and-fix the culprit for fear that it might otherwise lead to a proper disaster.
I have not been following other country forums, is this a recurring problem in other parts of the world or just UK? Might be a software bug specific to UK specific conditions. I do't remember hearing of it on MS/MX ... but far few numbers of those cars of course
So, personally, I would most definitely not be forcing the charge higher in case there is a real issue in the house wiring. (well, I'm a software bod, so i would definitely first do the "Lets see if it will do it again" test ...)
I don't know how feasible it is in practice, but for overnight charging might be worth turning off all circuits that are not needed over night - so just leaving bedroom circuit - and seeing if that makes any difference ... if it stays at max AMPs then likely to be a fault on one of the isolated circuits.
Other threads here have said that it was necessary to physically unplug a turned-off device to isolate the [whole house tripping] problem, so devices just being OFF may not be sufficient.
Normal for Tesla. "Chuck it out there" software development policy. Seen this plenty of times over the last 4 years, within a month or two it is improved / fixed and then users have short memories / quick forgiveness. I think it is a crap way of doing development, but maybe there is some upside I haven't considered ... e.g. additional feedback from irate! users which is, also, taken into account
I only have the 16A issue when the car was sleeping and a scheduled charge is started.
The house is 2 years old, the BMW i3 charges just fine and there has never been even the slightest glitch with breakers and RCDs.
