maybe time to trade for a newer version. but if you'd rather repair it, get tech stream and use the service manual to diagnose and troubleshoot. it s sometimes the case that you have more than one problem, but you can only follow the guidelines and hope for the best. you've got the battery apart, why not clean it up, replace bad cells, rebalance, reinstall, then see what's next?
generally, they don't know themselves. some things can get complicated, and the codes cannot narrow it down enough. they could be right, but that can get expensive if you're paying a dealer to throw parts at it.
