There are many factors to the successful regen equation. That is why we use data loggers as well as fault codes for trying to figure it out and we still get it wrong some times.
Great diagnostic strategy, call and video. The data tells the story and experience guides the way. Would be interesting to find out what some of the common failure modes are for the actuator. (I remember when Delphi first introduced them which they called them Smart Remote Actuator and that is what Mack/Volvo called them). Also, I have on my list to email you, just been swamped. Having a bite of lunch as I put a turbo on our 17 Ford F450 6.7L Powerstoke service truck, tired of my feet dangling as I lay over the engine bay!
Occasionally we work on a power stroke. We try to get our truckshop to pull the cab off. They do suck to work on. I’m swamped myself so not replying to comments that much and hoping the subscribers start doing my job for me LOL
My son who works for a different company went after a power stroke on the road. He had to change a broken steel fuel line and said he was up under the fender by the wheel well to access what ever. Sounds like they are not fun to work on.
