Hello hello. I recently received an error while charging about reduced charging speed. My 48amp charger was reduced to 32amps (LR RWD). I tested at the Tesla dealership at 40amps and its fine so I think it's an issue with installation in my home. I did it myself. It's a longer run (whole length of the house into the garage) and I used normal to low quality items honestly. Home depot stuff. It used to work fine, but now I get the error so I'm betting the car has changed criteria and was sensitive to power fluctuations to limit amperage.
My question is, is there a probable/easy solution to fix this? I was told it was probably the run length and would need larger wire to prevent this issue. Could it be a bad breaker? Loose connection in unit? If its too troublesome, I'll stick with the 32amps cause I'm not buying $200 of cable to save an hour charge time.
