Thank you for the suggestion. I have gotten in touch with a place out here on the west coast and they are looking into the codes for me.Very sorry to hear you story EVcommuter. I know about Gruber Motor Company, one the east coast I think. They only (as far as I know) rebuild/repair Model S battery packs. I wonder if there are any companies on the west coast who do that on Model 3 batteries...just a thought, others may know. Good luck.
