Hello. It could be worth checking the pec board inside the pem. If thay replaced the pem the rebuild team or parts department could have placed an order for a pem with 2.x pec pcb insted of a 2.5 pec pcb. Easy way is maybe check the firmware version on the vds display (diagnostic mode) or the battery is 2.x and the new pem do not have the 2.x pec board. But the fault codes indicate a low voltage at the pre charge circuit so most likely in the bms pcb. But a simple and easy check
