I have a 2003 X5 3.0i After ruling out all other possibilities on the Cyl #3 misfire, I have concluded cyl #3 coil is not getting a pulse. I measured the resistance on all 3 wires from the DME connector to the coil connector and got minus point 2 (-.2) on all 3 wires. Would this indicate a bad DME or a bad wire harness?
