YES that'st true, actuator can be replaced, Mine was at Freightliner dealer in Portland, Maine, but Detroit Diesel wont do it, they say they need to replace the whole turbo and actuator.

Some Freightliner shops do it specially if the truck is under warranty.They don't want to change the whole turbo. It's considered a half-s job. It's a pain in the rear to calibrate the actuator with a existing turbo. Mine took 7 hours of labor (paid by warranty) to calibrate this thing...after I leave the, dealer, 200 miles down the road, guess what? Problems..Never heard somebody that had sucess changing actuator.

Detroit refuses to replace actuators because it can be a problem in the shaft that commands the VGT on the turbo and they can't fix it without replacing the entire turbo . I don't know. Mine didn't worked. I kept having problems on the turbo side.

Can`t fix it you have to replace the turbo. What year is your truck ?

That's not true depending on what year series 60 it is you can buy just the actuator. We have a 2006 and just price a actuator 198.00 dollars for one. As far as repairing them I don't think so.

it seens like an sensor is acting and sending that info to ecm that is derating your engine horse power. can be the one in front of the turbo, most likely. i had the same thing not producing turbo and was the o2 sensor acting up.

good luck

If you have a (V G T) turbo you should change it to a non vgt

Depends how the delete was done, if they left the older turbo with the sensors in, its a good chance that those sensors are not dead.

Swapping to a Non VGT turbo will leave those sensor present on the OEM Turbo throwing faults and consequently derating the engine.

Not true. You must get someone that knows their stuff. Turbo pressures / rpm axis must be remapped if you change to old style turbo. If you are driving it yourself, get a turbo without a wastegate. A good ddec 5 egr/vnt delete has about 140 parameter changes.
