I'm new to forgien cars, but I know on GM they have a clutch for the fan and if that goes out, the fan that draws air across the radiator when you are at a stop won't turn and your temp rises. And when you start moving, your motion pushes air across the radiator which cools and the temp goes down. The pinging could be from the high temp too.
