My S40 caught on fire a few weeks ago and nobody seems to be able to figure out the problem. I was in a snow storm trying to power up a hill. We were doing great when all sorts of warning lights started to come on like the brake and abs. We stopped as soon as we could, since we were making our way up a slick hill, and the car started smoking. When we opened the hood, there was a small fire which got bigger. We used the snow to put it out. After 20 minutes or so the car seemed fine. When we checked the radiator fluid level, it appeared to be completely gone. The only thing visibly damaged due to the fire, was the a plastic cover. I was in an accident (front/engine damage) a few months ago, and we are wondering if the repair shop forgot to put radiator fluid back in or didn't replace something they should have. Does anyone have any suggestions? The car is now at a Volvo dealer, who also has no idea how/what happened. They are waiting for a special engineer to come and check it out. Help, I love my car and want it back to normal!!
