I'm afraid I don't have the precise answer for you, but..

this similar problem existed for another member and another car (a 300E-124) I think. His problem was that the car wouldn't start when parked on an incline with the front facing "down" toward the bottom of the hill. Since I don't own that type, I don't remember the answer to solving the problem, but I think it was a "safety factor" that Merz had and was easily fixed.

Try searching for "300E not starting on hill or incline"

sorry I couldn't be more precise, but it MAY be that you have the "same" and can fix it easily.

I did a search and couln't find the thread to which I was referring.. maybe it was another forum, but I spend most of time here and not on others. sorry, but good luck. I think the previous posts should help you determine the problem.
