Actuator Linkage jams, Rust, delicate Worm Drive Gear, Turbo Vanes, Low Boost & pLHM!
Need some accurate answers to Actuator problems so I can gauge best course of action.
On my year 2000 208CDi Partial LHM was, finally, diagnosed as "jammed shut rusty as hell turbo actuator".
The mechanic has, somehow, moved it so that it is now jammed open.
Reading all of the threads I possibly can about the actuator and the turbo veins it operates I cannot fathom 2 things:
1. Is it always the actuator arm which jams with rust or something in the Actuator itself? in which case why am I being advised I need a new Actuator?
...‘AquaPuttana’ referred to this issue in a 2009 post as “the turbo vane actuator linkage being frozen that sent the ECU to LHM limp home mode”
2. how can my actuator have been safely moved to open, leaving it now jammed open, without having caused damage?
Does my year 2000 T1N have the delicate worm drive to control the turbo vanes? Or was it different with earlier Sprinters? ‘slowgsr’ refers to this as the “worm drive gear in the actuator” in a 2010 post.
This may sound a bit mixed up so please be gentle with me I am not a mechanic!
Knowledgeable feedback greatly appreciated!
