cxn613 Posted July 15, 2015 Share Posted July 15, 2015 Throws active code mid128 sid27 fmi7. Erase code and comes right on again. Seems to run fine. Would this be a issue with wires going into actuator box or the single wire going into center of turbo?

Dieselwrenches Posted August 1, 2015 Share Posted August 1, 2015 Unless you've had the actuator of yourself or anyone else and it didn't get calibrated before going back on code is most likely because of sliding ring sticking and not moving freely in turbo due to dot build up or debris, you can tell by unbolting actuator and turning sector gear on turbo. Should move freely not bind up. After removing actuator it will need to be recalibrated with dealer software.
