Will, on the 119 engine that should all be handled by the actuator, not an idle control valve.

That's what I thought, however Fastlane does show an idle ctrl valve for my motor.

i guess since my motor is a euro spec G not sold in the US fastlane doesnt actually have .996 listed. im using a similar e320 for reference.

i dont see an idle control valve. im waiting on my parts for a reader to show, not much more specualting i can do before then, but i strongly belive its the actuator. ive had this issue for over a year, and last month a mechanic working on my car accidentally cut 6 wires in the harness. (long story, i'll do the work myself from now on). when he did so the idle was gone completely. i had to booger rig the throttle to make it drivable. i noticed thos couple day though, that the surging was gone. when i discovered the wires and repaired it, the idle was back, but so was the surging. looking at the lines, i lost a temp sensor and the actuator.

so, i bet its the actuator. im looking into options that dont include a 1200 dollar part on a weekend wheeler.

i notice some sites that rebuild them for 3-400 bucks, or i could do it myself. i think ill split the harness plug and give it a shot.

if anyone has an actuator that degraded cheap, i'll buy it off of you for a practice run. part number 000 141 57 25 i think.

I read that internal wires rot inside actuator,and it can be repaired by ones self.
