I have a model 3 dual motor. My charger used to work fine about 5 months ago. Now for past couple months, every time I plug in the charger, I have amperage drop. Sometimes it goes down to 5 amps sometimes 10-20...it varies. When I turn off mobile access it charges at 48 amps. I don't have any app that would be causing that issue other than Tesla app. I also have Tesla solar and my inverter was down for about a month. During the time inverter was down it charged at 48 amps with mobile access on. I have emailed Tesla support several times and hasn't been helpful at all. All they say is wiring is the issue. I have tried turning off the phones that are connected to car and that hasnt helped at either. Now my inverter is back up running and I have amperage drops again. Anyone know what would be causing the issue? I don't suspect it's wiring because it charges fine with mobile access off...I have logged into the wall charger also don't see any error codes.
