Two wires rubbing together near x107 may be the cause. This large connector came loose from its mount and caused damage to two wires , either b10 and c10 or b1 and c1. These are nox sensor power and ground wires for nox 1 and 2. No word from the dealer yet. I may just go there on Tuesday and pick it up ready or not. I did tell them about the two wires.
