Update: the rest of the story.....
Problem is back, below is description of problem. Installed rebuilt unit in a 1995 E320 Sedan. Initially the unit operated correctly, 2 days later, operation became intermittent. Symptoms are intermittent high idle speed (1400 RPM in park, 1000 RPM in gear) and inoperative cruise control. (either both symptoms are present, or neither are present. never one without the other) Shutting off the car and restarting will sometimes cure both problems, but they both reoccur. Retrieval of stored fault codes (via impulse code reader, not HHT) consistently yields the following: Diagnostic module: code 6: Idle speed control inoperative ECU module: code 8: Idle speed control (ISC) system at upper or lower control stop HFM SFI module: code 2: EA/CC/ISC control module (N4/1) or Safety contact switch (M16/1s1) or Stop lamp switch or Cruise control switch or Actual value potentiometer or Starter lock-out/back-up lamp switch or engine speed signal or vehicle speed signal or closed throttle position switch or safety relay in EA/CC/ISC control module Out of desperation, I replaced the remanufactured unit with a known working unit pulled from an identical fully functional vehicle. Idle speed/cruise control now work properly. So far, there is no indication of intermittent failure. Returned unit to Beckmann for testing, they confirmed reman unit was defective. (the drive motor was bad) Hope this story helps someone else........................

Before reading your 'conclusion', while reading the post, I came to the conclusion that the ETA was bad. So I guess it was.
That's a bit troubling since it's supposed to be good . . . hope Beckmann improves its final testing methods to ensure that doesn't happen again! You have been busy! Tnx for posting your added steps.

My diagnosis was also a bad throttle actuator but I refused to believe it because it was supposed to be a fully tested reman unit. In all fairness to Beckmann, this unit probably did test OK prior to them sending it to me. Intermittent problems are always troublesome. By the way, the motor is the only part of the throttle actuator that can't be rebuilt. It is pressed in and replacement is not possible.

I'm not 100% sure but I think Beckmann can recondition the potentiometers. They have some kind of proprietary process were they reapply resistive material.
