    Huh. Does it charge normally at 240 V? Maybe something with the relays in the HVJB?

    Sounds like a problem with the charging circuit...

    Yikes! This is a good reminder to make my new S to a Supercharger and make sure it works. :)

    Could be any number of reasons. The only way to know is to see the errors it's throwing.

    If you're also getting "Car will not start", most likely is a leak in the pack connector gasket, as I'd earlier documented.

    How many kilometers do you have on your car?

    What percentage of charging do you DC fast charge?

    they are coming to pick it up on 2nd june and leave a loaner its done 17k miles and i only use the superchargers once every two weeks

    it originally stopped charging on sunday at a supercharger (it had been raining) i unplugged and restarted and was fine then a fault showed this morning, i called the service center and the told me it was them that knocked out dc fast charge after looking at the logs, and it needs to go in for investigation.

    Yes - I had this message before. Apparently there was a leak near the charge port which resulted in some water ingress (your issue may of course be different). Charge port and a cable (inside car) needed to be replaced.

    Car was in and out in a day and has not happened since.

    I got this error and symptom after attempting to supercharge last night. Fortunately I had sufficient range to get home and charging from 240VAC here still functions. SC indicates (after viewing the logs) that a fuse in the DC charging circuit is blown. Not sure why -- perhaps a malfunction of the Supercharger or some additional problem with the car (TBD). Going in for service next week.

    Nope, nothing but Florida sunshine here. No car washes, not even a puddle.

    I had the same issue months ago on my 2015 P85D, it was the on board charger, they changed it to the new 2nd generation, 1 day to replace.

    The onboard charger is not involved in supercharging. Folks that have had a bad master charger are still able to supercharge while waiting for the fix.

    While it isn't an active participant in Supercharging certain failure modes of the charger will prevent Supercharging. So it is involved.

    I'm struggling to think of a scenario where it would be involved. The HVJB relays completely bypass the onboard chargers while supercharging. Thus, they are isolated.

    Unless there is a short which carries through all the way to the DCDC converter (in which case the HVIL would trigger and the car wouln't even be driveable).
