My car will go faster than 20 mph we have had snow and ice freezing weather for the last two day. It did not crank right away but eventually it did. Its seem as through it struggling and never goes to the next gear. There are no faults light indicated. It is not in the winter mode.
Car will go faster 20 mph in weather 32 or below. on 2002 Mercedes-Benz C240
