[QUOTE="arjanh, post: 47780"] [b]ruckeln[/b] After measuring all the values off my car my conclusion is that the fuel (ca. 30 degrees) and the coolant water becomes to hot (ca. 113 degrees) This especially after a long trip and then stand stilll and then ....drive away. The software cuts in "safety mode" and wil set you ignition ca. 6 degrees pre. When driving away the temperatures drops and everything is ok again. Also the fuel becomes to hot, the hot fuel passes the hot engine bay and heats up ...it heats the rest of the fuel in the tank (return line). This effect is worser when your tank is almost empty and hardly noticeble when your tank is full. The motronic also sets pre ignition when the fuel is hotter then 30 degrees celcius. I can't figure out it's done by temperature sensors or knocking sensor. Maybe somebody can tell me this ? [/QUOTE]
