X55, what did you find out on this problem? My E sometimes has this problem after a second start. For instance you stop to get gas and after starting the car and putting it in Drive it has a faint lurching. After driving it seems the problem is gone. Only seems to happen after a warm start. I have replaced plugs and and wires with new OEM. Also not getting any codes. My W202 had the same lurching feeling when the EGR line had come loose.
