At 150,000 miles my 94 E320 had the same code and lost the cruise control. In addition, I heard a growling/grinding sound from the area of the throttle actuator. A rebuilt throttle actuator from 4Mercedes.com and a few hours of my time cured these problems. If you do it yourself, buy a new gasket and a new intake pipe (part number 104-141-09-90)
