Was testing my new Evse, and didn't realise the car was already full, after forcing some charges I got the high voltage error. This is not related to the battery liquid level, already shunted the sensor plug with a 24k resistor. Tryed to erase the error but it came up 1 second after... Tryed also disconnecting the 12v battery for some minutes, didn't help.. Dealer can only receive the car in middle September... Can you give me any ideas to try? Thanx a lot.

What exactly did the error say?

How did you force it to charge if the battery was already full?

Just leave it for a while, the HV battery will discharge over time
then clear the errors and try again.

Maybe the HV upper voltage limit has been reached
