I've got a 2007 E350 wagon with about 55,000 miles. Yesterday I got a red malfunction light on the instrument cluster. The malfunction light looks like an outline of a vehicle with an arrow pointing up from the bottom, in the middle. I'm guessing this is an auto leveling malfunction, the owners manual just says don't drive over 50 mph, and take it to a dealer for repair. I like to make repairs on this car myself. Any ideas what's going on here, or could it be a number of possibilities.
