Can't Supercharge :(

[mat300z]

So my 2014 Model S 85kw won't supercharge anymore. Tesla service center says it needs High Voltage junction box and a new charger assembly installed. This comes at a cost of $5,260 or so. It still charges fine on A/C home charger. Have any of you seen this problem? Screen say "unable to DC/Fast charge and error code BMS_U011.
Any help or advice on this would be appreciated. I don't have a lot of trust in this particular service center because of past issues but it is the only one close to me.

You have 2 different charging boards, the AC/DC board (for AC 120V or 240V charging) and the DC/DC board that handles all the supercharging. It sounds like your DC/DC charging board is bad and needs replacing.

Are you in Florida? I think there is an Electrified Garage there. Might be worth a call to them to see if they can do the job at a lower cost.

How hard is it for a person to change it themselves

I get the BMS_u011 as well on a Model X 90D. What did you end up with?

Any resolution on this? I can't charge my 2016 Model S at a super charger as a result.

My 70D is at Tesla right now for a new Gen2 Charger. That should fix the supercharging

Crazy, mine is sometimes working. I've been reading people suggesting it could just be related to corrosion on the connector. I might try cleaning it to see if it helps. Gonna have to find the time though.
Thanks @radiohead7778

Any follow up solution on this error code?

I think multiple chargers were bad. It’s been ok ever since
