Hello everybody - first time posting (hopefully I'm using the correct form)
I drive a 2022 M3LR in the USA with 7k miles. For the first 10 months of ownership the car worked perfectly.
4 weeks ago after heavy rain/snow/salt, I started getting CP_a051 which indicates a fault in the Charge Port door (it would not open when pressed). Tesla came to my house and installed a new Charge Port Door, and the problem was resolved.
A week after my mobile service, I stopped by my local Supercharger (V2) and could not get the car to charge. As soon as the current began to flow, I would get BMS_a063 "unable to charge. Disconnect and retry." I tried 6 different stalls with the same result. To ensure this wasn't an external supercharger hardware problem, I even tried a stall that someone had just successfully used.
I scheduled a trip to the Service Center. They connected the car to their Supercharger and it worked normally, so they tightened the Protective Ground bolts on the inside of the Charge Port and sent me away. Now I'm getting BMS_a063 right as the Supercharger reaches the charge limit I set. As soon as the loud contactors clunk and the charging stops, I get BMS_a063. So sometimes it prevents me from starting to charge, and sometimes it happens as the charge completes.
Level 1&2 chargers work normally. Perhaps this is a problem with the Proximity or Pilot pins communicating to the car while Supercharging?
I have seen several posts with nearly identical symptoms in the UK forum where the "3 Phase AC Charge Port W Harness" was replaced solving the problem. However the USA cars use an entirely different style of cabling behind the Charge Port.
Long story short, I scheduled another trip the Service Center, and I am curious if anybody has any experience with this issue. I have a cross country road trip scheduled for April, and I am nervous I'll get stranded at a Supercharger. I'm desperate to get this problem resolved ASAP.
