Following a firmware update to 2020.24.6.9, I started to get an error message "Charging reduced - over heat detected at the wall connector". After plugging the car into the charger, it charges fine at 32A for 2-3mins then this message pops over, and the charging gets reduced to 16A (15mi/hr). No other error messages apart from this. Normal green T on the car, normal "flowing" green on the wall connector. Phoning up the service team, their remote diagnosis team concluded that the issue is related to the charger installation, and I should get in touch with the electrician, which I did and then the blaming game started between Tesla and the company which fitted the charger. Tesla has now pulled my car log and are investigating further ! Issue not resolved, and I still get this msg 2-3mins max after plugging the car in. I started investigating myself, first by having a closer look at the charger itself. It is fitted outside in the shade, the unit is not hot (even after removing the face..yes I had my brave pill and did that!) nor is the connector. I then went earlier today to a destination charger (a country hotel/pub) which has few Tesla wall chargers available free of use to see if I get the same error. It seems everything is working fine, HOWEVER, this particular charger seems to be installed on 3 phase power, so it is already working on 16A even though it's juicing 45mi/hr..so not really comparable to mine at home, which doesn't trigger this error when I use it on 16A (although mine only gives 15mi/hr as it's installed on a single phase) Oddly enough, the hotel owner came out, very pleasant lady, saying that there was earlier another guy who was also testing his car for the exact same issue! she says there is hardly anyone using these chargers due to the lockdown and due to the fact that the hotel is still closed for business To me it's too much of a coincidence that this error only happened the following day of a firmware update + plus the hotel owner's story! I'm wondering if anybody out here faced this same issue?
