Help! Incorrect Freon in AC Lines

[2014 MS in CA]

I inadvertently had R134-A with PAG oil added to my 2014 Model S AC system and now the AC is working intermittently. I know now this is the wrong type of Freon and can be damaging to the compressor.

The question I have is: what options do I have now?

(1) Can the Freon be vacuumed out and replaced with the correct type?
(2) is the AC compressor likely ruined and the entire system needs to be replaced?
(3) is there even worse damage that was created beyond just the AC system?

1. yes
2.possibly
3. most likely no

If you over pressurize the system you can blow some internal seals. Try letting out some of the freon

Only thing you can do is flush the lines. If there's contaminants in the compressor, dryer, you're SOL as the mechanical parts in the ac system cannot be flushed, ie. replace only.

Thanks for the quick help. Really appreciate it!

Any safety issues for the battery health to drive it before service can be done to replace the mechanics parts?

Only real risk to the battery is just inadequate cooling. If you're not driving far or fast in desert heat, it's probably fine. Refrigerant doesn't pass through the battery.

nope, it is a separate system

The battery is very carefully monitored and it will force limited driving/no driving/limited charging it if would damage the battery from overheating. So I wouldn't be concerned about the battery, other than you could get temporarily stranded if the battery temperatures get too high and the AC is not working and it requires a shutdown. If a shutdown is forced, you will get some limited warnings with enough time to pull over.
