My 2003 CLK55 stalled at a light, so I look down at the dash and its lit red with "Visit Workshop" and would not start. After pushing out of the intersection and a flatbed ride home, it starts up, has the check engine light on, with nothing in the malfunction display screen. What's up with that?

Has anyone heard anything like this? It only has 43K miles on it, and feel disappointed.

I love this car, but is this a sign of more trouble ahead?
