Wall charger acting strange since M3 software update

[docdent]

Since updating the software in my M3 to 2020.24.6.9 my wall charger has been acting weird. The wall charger is connected to a 60A breaker. So, it charges at 48A and 43 miles/hr.

Since the update, it has randomly dropped the charging A giving a low quality grid detected warning. It doesn't happen every time and had only done it since the update.

Has anyone experienced this and what did they do?

I would shut power of the wall charger and remove the front cover and look inside with a bright flash light, look for wires that are hot looking swollen from extreme heat. At 60amps hoping you are using the correct gauge wires.

Maybe also use some type laser temp gauge...to point out any loose connections.
