Level 1 and 2, both don’t charge. The car shows up clean on Tesla platform (confirmed by Tesla) it was a clean title car as well. I swapped the charge port ECU as well, checked pyro. No luck. Could this be a BMS issue? I guess the question is, will the battery ever charge if it has been uncharged for a year? It was at “0” when I received it. Or do I need to reset\clear something through toolbox (even though I don’t believe it’s a vcfront issue as airbags seatbelt and pyro are all in good order)By "charge", do you mean AC (Level 1 or 2) charging or Supercharging (DC)? If the latter, and the car was declared as "salvage", Tesla in most cases will disable Supercharging as a safety measure. I believe you can still AC charge a salvage car.
Tesla doesn’t wanna touch the car post crash. Basically want me to go through insurance. Insurance won’t work cuz that’s how I bought the car (condition)Can you make a service request?
Do you mean they want you to go to a bodyshop? Tesla Service centers dont do major repairs, so they would tell you to go to a body shop. Saying they told you to "use insurance" implies that they would fix it if it was billed through insurance. Insurance is obviously not going to pay for it if you bought it that way, but thats just a form of payment. They shouldnt care if you pay yourself, if its work they do.Basically want me to go through insurance
It’s unfortunate but most Tesla certified body shops I reached out to and explained exactly my situation have not been helpful much, they have turned down or the lack of interest in the job by saying it will cost a lot out of pocket (which leads me to believe they are interested in insurance work only) I have reached out to 2-3 in NJ and similar feedback or simply saying they are backed up for few months and won’t be able to get to my car.Do you mean they want you to go to a bodyshop?

If its a clean title though, you should be able to pay for a body shop to look at it yourself. You specifically said it was a clean title, so that should be possible.
As for "is the battery toast if not connected for a year" I dont think there is a definitive answer to that. You will likely need to engage a company that can evaluate the battery for you.
Some people on Discord seem to suggest the HV battery may need to be changed if not charged for a long time.I don't think the battery will die. Lithium batteries simply don't die because they're not charged. You may definitely see degradation to some effect. The 12V battery may need to be changed.
Isn't there an independent shop that could test it out. By the way how much did you buy this for.
I'm a bit confused by your posts. You say that the battery has been dead over a year. Are you saying that you've been towing your car to test a SC or level 2 charger? What is the state of your 12V battery?Some people on Discord seem to suggest the HV battery may need to be changed if not charged for a long time.
I bought this exactly a year ago for 25k. You think it’s a worth a shot to try toolbox for a day and clear all codes?
Sorry for the confusion. Yes I have towed the car to and from body shop to my place for the last one year I have owned.I'm a bit confused by your posts.

Have you gone into service mode and checked the errors and HV battery status there? That's probably the first thing I would do. When you plug in to charge it should also show an error (either in the car or UMC) if it refuses to charge. Just saying it isn't charging isn't really helpful for diagnosing the problem.Sorry for the confusion. Yes I have towed the car to and from body shop to my place for the last one year I have owned.
I had replaced the LV battery once already which was depleted by the body shop. I’ll probably have to buy another one, but was also wondering if I can try an external PS (20-40amps) to provide power for LV, or I can get another one.
I have not tried SC station but have only tried slow mobile charger at home to charge.
Is there a chance of the HV charging once I replace the LV and tow it to a SC ?
You’re correct that the diagnosis is nearly impossible by posting a generic issue. I have attached some pictures from the service mode. I these may not be 100% accurate as some may pop up while I was swapping or checking the continuity on Pyro or while the LV was disconnected and the car was powered with an external power source. Hence the reason I was asking if I should clear all codes.Have you gone into service mode and checked the errors and HV battery status there? That's probably the first thing I would do.

For example, in the owners manual even for "unable to charge" there are 40(!) different error codes, which shows how many different possible causes there are.

I remember reading people having the body shop leaving the car depleted for months and they were able to get it back up by plugging it back in. 1 year is extreme. Also if the car was bought at auction, most of those cars are accident cars that may have the HV battery disabled. Sounds like you never checked if the HV battery was working immediately after it was purchased, so it may have already been sitting even for longer at 0 (meaning even longer than a year) and already was disabled then.
If this car has a clean title then why are you not getting it repaired under warranty?You’re correct that the diagnosis is nearly impossible by posting a generic issue.

As for HV battery being disabled, I had a certified Tesla shop run a check on the vehicle VIN and the tech was nice enough to tell me the car is not disabled or marked salvage in Tesla DB.
Again this was purchased at an auction with clean title from Hertz and I was able to transfer ownership with Tesla and get the title changed and have Tesla confirm it’s not labeled salvage in their system.
Any other insight would be helpful.
Tesla runs the VIN and sees it was not repaired at a “certified” Trashila shop. If it’s not fixed at a certified shop, they won’t touch the car and not honor the warranty. As per Tesla if the HV battery is not charged this comes under negligence and voids warranty for any HV battery related parts.If this car has a clean title then why are you not getting it repaired under warranty?
