2013 S85 - Only charging at 6kW in AC ?

Good morning from France,

I recently bought a 2013 Tesla S85 Signature. I trully love it and am currently learning about how to use it efficiently :)

The car has 195,000km, no major maintenance (that I've been told) but still around 90% of the battery life left, so pretty happy overall with this first electric car.

As it's a Signature model, it's nearly equipped with all the available 2013 options including the double onboard charger (2*11kW if I'm not mistaken).

But, here comes my first issue :
When charging in AC, it never goes above 6kW, even on 11kW charging stations.
I don't have this limit when supercharging (thus in DC)

Here are 2 different examples :

1. Charging on a Tesla wall charger set up at 11kW

2. Charging at home on a 230V - 32A using the UMC

As you can see, I never reach the Amps limit as it's never going above 6kW.
I asked for a service for Tesla and they are charging me 2500€ to change the onboard charger.
I know that there were some fuses issues on these generations BUT it seems like my problem description is not the same as the one I saw when the fuse was blown ?

Does anybody have an insight or have heard something about a similar issue ?

If not, my plan is to check the fuses during Christmas Holidays

Many thanks for your valuable help,
Arthur

I wanted to check the fuses this morning but … Unfortunately I found out that I have gen2 chargers

From my understanding, these ones are not equipped with replaceable fuses unfortunately.
It seems like I have at least one phase down on the main charger, does that sound right to you ?

What are my options except paying Tesla for a 2.5k€ replacement ?
Is it possible to ask them to replace the main charger with the slave one ?
Is it possible to change it by myself or will I need Tesla to program it ?

Many thanks
