After a very short drive my daughter was sitting at a traffic light in her GL320cdi SUV when she noticed a big white cloud of something that looked like it may have come out of her exhaust. There was no other car close by that could have produced it. The car has just had it's first major service since she bought it. She says she "may" have gotten a tankful of less than the ultra low sulphur fuel. She hasn't seen any more white clouds behind the SUV since then. Does anyone have an idea what could have caused such a cloud? The only thing I could think of would be a headgasket letting water into a cylinder. The dealer is 60 miles away, so driving it there could be risky if there is something seriously wrong. Thanks, Gerry
