Problems regarding chargeport on old Model S

[ThisStockGood]

Hi guys

My old beloved Model S 2015 (Europe charge port) will not Supercharge ("DC Charging disabled - try AC charging instead").

The Ac charging is working perfectly.

I have this picture of the charging port. I see some corrosion - and maybe som weird stuff on the top left pin (communication pin I think). Looks like som black plastic that is stuck on the pin, but it is hard to tell for me.

Any good guesses on what could be wrong? I have reached out to my Tesla SC, but they are quite busy at the moment.

Thanks!

Likely a problem with the High Voltage Junction Box which I believe is inside the AC charger unit in this year car. Last I knew replacement was about $2500 USD.
