Two problems related to underhood wiring have been reported for the 2001 BMW 740. The most recently reported issues are listed below.
Smoke from engine and burning wires and electrical connectors at the plug to the engine cooling thermostat small fire extinguished with a small amount of water.
Smelled smoke in car before starting engine. Got out/ opened passenger side door, and saw fire coming out down near the seat area. Towed to BMW, and they stated a switch may have burned out and caused this fire. When air gets to fire it ignites. Normally fire would burn out but since the door was opened air got to wire and ignited a flame. Please provide any further information.
