    Default LML wont start after D

    2015 LML and did a D for the dpf and egr. Downloaded the tune from a reputable tuner and cannot get truck running. It ran 1 time for 5 seconds then died. It just cranks and other times it clicks like a dead battery but both batteries are at 80%. I am stuck here no idea why it won't start or even crank sometimes.

    Sounds like you flashed the wrong OS into the ECM. Did you complete an OS readout prior to requesting the tune?
