Okay so, went to the dealer, no codes. Asked them to do battery pack test and they come back with a 12v battery test . Then I explain what I was asking for and the advisor had no idea (which I expected) and I told him to follow the PDI and complete the test, they did and gave me a print out of a very detailed “live results” Pack came back good at 55.0Ah So hopefully no harm was done and the new juice box will solve the issue (provided I don’t have the issues bfd has had )
