Main engine wiring harness destroyed, engine still ran- temp, fluids, cam timing, mass air flow, fuel rail, throttle position -sensors, instrument panel. Had checked oil two days earlier, was no damage. Wind screen washer light came on when I tried to start engine, checked and found damage -was one of the sensors which was damaged - fluid bottle was ok. Some minor wires were still attached. This could have happened on the highway and caused an engine malfunction. There was always a slight odor in hot weather or when on a long run- was the soy based polymers Volvo used without any "odor inhibitors", the looms coverings do biodegrade quicker in hot weather exposure without an inhibitor and disintegrate leaving the loom to open up and be exposed to damage! the hood insulation was also destroyed and had to be replaced total replacement and labor $2. ,827. 42.
Dash warning message showed third brake light not working. Subsequent trip to dealer diagnosed as defective wiring harness in rear tailgate. Scheduled for replacement.
