“Engine compartment fire in 2006 S430 Mercedes-Benz ? January 16, 2014 as I accelerated to get on the road, I smelled a strange odor. I thought it was coming from a truck we passed. I opened the window & turned off the heater to clear the air in the car. In a few seconds, I closed the window and re-started the heater, which immediately filled the cabin with heavy smoke. I again stopped the heater and opened the window. The smoke cleared and smelled something burning. A few seconds later, I saw flames coming right out of the air duct grill in the hood. …”
