White "smoke" coming from car while Supercharging

Hi everyone

I had a mobile technician at home today, nothing serious just a few cosmetic things to be adjusted.
About 2 hours ago I went to the nearest Supercharger, a 125KW Charger. I had about 18% left and wanted to charge fully (in preperation for a trip tomorrow).

I was minding my business, watching a video on Youtube when just 5-10 Minutes into charging i see a lot of white smoke coming out of my front wheelwells, frunk and front bumper.
I immediately ran out of the car to unplug the charger and called the same mobile technician. While waiting for him to arrive, I see another MY having the same thing (just a few seconds long and not alot of smoke)!
After about 30 minutes he arrives, checks my car and tells me that everything is in order. Apparently there's condensation leaking from my low pressure valve (connected to the Super Manifold), atleast that's what I'm told.

So his advice was to just ignore it and if it happens again, I should oben a Service appointment in the App (not as a Service/ Checkup, but rather as a Note to the technicians).

I'm super paranoid to drive with my M3 (2021) again.

Has anyone else experienced this?
Just happened this morning while charging my (March 2020) MY. White smoke while supercharging, in cold weather. Never seen this before. I’m about to contact service now.

Relax everyone. Under the hood is a plethora of bare aluminum pipes and pumps that get very cold

This cold metal attracts condensation:

And the water steams off during supercharging because all those pumps are working to heat the battery:

It likely appears in a burst because the system was previously only trying to heat the cabin, but when you started Supercharging a valve opened to begin directing heat to the battery thru a different section of plumbing that was still wet/icy.

On occasion I also release vapors. Particularly after a meal with lotsa beans.

Seems like this only happens in cold weather huh. Cool feature. 😁

When my 2021 Model 3 was in the SC last week getting a couple of rattles sorted, they also carried out the following which I never asked for, they just told me they would do this while they had my car.

Yes, just did. While supercharging halfway when smoke was coming front my frunk and right front wheel. I immediately stopped charging. There was no smell of burnt or anything.

The same steam situation just happened to me 1 hour ago while charging, the weather was very foggy (humid) and the temperature was 6 degree Celsius.
I also panicked at the moment, stopped charging and the steam stopped immediately.
I drove 40km at motorway speeds after without any problems or smell, so everything looks fine, just some perfect humidity water combination

Wrong color smoke. You’re talking about brown smoke, not white.

My household heat pump will also steam in the winter. It goes through defrost cycles to keep ice off the outside coils. It does it the most on cool humid days.

could it be similar in the car?

Had the same thing moments ago. Smoke came out from the front driver side tire gap during supercharging at a v3 station. Weather is 4c. I hope it is ok.

OK, I'll be the pedant here. What you are seeing in the photo of that locomotive is not steam but condensed water vapor. Actual steam is invisible and will strip the skin from your bones in seconds. Especially from a steam powered engine that will operate at very high temperatures and pressures.

What you are seeing from your car is also unlikely to be smoke but water vapor. In cold weather it is very common as components heat up.

It just happend to me today while i was supercharging my Y at Buena park, Source Mall.
the security guard calling me that my Y is smoking when I returing from restroom.
Right away, I turned off the charging and unplug supercharger and opend the hood, remove the inner plastic cover at air filter to check.
The smoke stopped right after when it is unplugged from supercharger and did not smoke again.
I checked out under the hood and where the right tire is with flash light but nothing i can find visulally.
after 5 min, i plugged back and charged 80% as usual without any issue.
this was freaking moment.
