2001 freelander td4. 4x recon injectors, new fuel pump, synergy 2a and pierburg MAF, silicone boost hoses, disabled EGR, BMW crank case filter, new VNT filter.
It runs well enough with no warning lights, but seems a tad slow to pick up and is dead flat when pulling a trailer....really needs thrashed through the gears to get any speed, but once cruising seems ok. Everything else seems OK. I found a small vac leak due to a perished hose end, so repaired that and checked all the other hoses. The VNT appears to do nothing. I bypasses the solenoid valve and plugged the vac line directly onto the VNT actuator and nothing moved. Pulling or pushing on the linkage does nothing - it appears to be jammed.
From underneath, what way should it move? I assume it pulls downwards towards the ground?
What is its course of movement.... Looks like maybe 20mm or so max?
how much effort should it take to move it? I assume it should be free enough to be moved by hand? I made up a wee hook and tugging on it gives no movement.
So.....if it's jammed, is this something repairable? I assume with the turbo off, I will be able to dismantle enough to get at it, but will it require a full stripdown of the turbo?
If I make up a sturdier hook and give it a serious yank/dunt, will it free off or will I more likely break something internal or just bend the arm?
cheers.
