Hello to all,
although the l322 in question belongs to a friend, he tows my partners horse box and brings it to me with problems, so I now consider I have a part share in the bits that work.
Anyway, big rattle, followed by replacement engine, (way out of my league) lots of problems with the guy who did the work, ran for 30 mins then fault came up, "TURBO ACTUATOR". So, bit of reading on the net and we tried to free it off, should be behind a heatshield, drivers wheel arch, Jacked up, axle stand, removed wheel arch plastic, no heatshield, no sign of actuator. Can any one tell us where we are going wrong? It is a 05 vogue 3.0l TD6 L322, that's all I know, hope it make sense to someone. Many thanks, Bluedrifter

Take it back to the guy who did the work, he is liable.
 
I can tell you that you are looking in the wrong place.
You can just about see it if you look down between the inner wing and the air box on the left side of the engine as you look at it. If you move one of the main harness cables, it unlclips but make sure you clip it back or it or it will drop down onto the exhaust manifold. The actuator should be fully open or extended to the right with the engine off and when you start the engine on idle it should fully retract or move to the left - from memory..
I'll find the link to my TD6 turbo removal fun
 
Here's the link to the guy's turbo change thread i added to
https://www.landyzone.co.uk/land-rover/td6-turbo-change-how-too.253209/

There is a reservoir that you can see in the attached and below that is a solenoid. The reservoir supplies vacuum to the solenoid and the pipe coming out of the solenoid goes to the actuator that you can see in my other photo.
Easiest thing is to look down with a torch and see if it is moving like I said above, check the pipe is connected to the solenoid.
Or as @Datatek says, take it back and let them sort it as it can be really simple or a complete can of a different type of fish o_O

No bother, keep us posted.
Keep in mind that although it may say turbo actuator, the actuator is controlled via the electronic solenoid which in turn is controlled by the engine ECU and that tells the solenoid how much to vary the actuator pressure based on what the MAP sensor at the back of the engine says. The amount of pressure is also relying on a healthy vacuum pump and pipework which can also be prone to failure.
The internal variable vane mechanism is also prone to becoming seized but the actuator diaphragm itself can also become faulty as can the internal turbo blades.
The diagnostic reporting is very good but can also be misled as it will assume that if the manifold pressure isn't correct then then the actuator isn't doing as it is told but that may not be the actuators fault.
i think that has made it complicated enough, at least start with the actuator and go from there. :)
 
I had a similar problem on a freelander, which also has a variable vane turbo, after some head scratching I checked the vacuum pipes that run across the top of the engine and down to the actuator and found that the pipe had worn through at one of the securing clips which therefore meant that the actuator never got a full vacuum and hence didn’t get full travel on the vanes or full boost. Replaced the piping and she then went “like mi dads oss” :D for a freelander that is. :rolleyes:
 
It’s common for them to wear through , I bought about 3 metres of cotton braided pipe for a few quid

I had to free mine turbo actuator off, is an electronic actuator on mine , what a bleeding job is was to get to it , also found a broken jubilee clip on the inlet intercooler hose, just had enough room to get a new one on there , indeed made a lot of difference as it was dangerous going into limp mode down the motorway or up a hill

Also found some good pics of how the vanes open and close

Well..............my friend had an incident where his wife got behind the wheel after dropping him off only for the truck to start moving on it's own, there ensued various hi-jinks and screaming, ending with it back at the guy who put the engine in, someone forgot to tighten some linkage or such thing underneath, any way sorted that then addressed the turbo problem. Said "could be the turbo we took off your old engine, did seem very loose around the vanes, if you get another turbo, I'll fit it" My mate did this and now it's better than it has ever been, changes gear well without revving it's nuts off, more power and more MPG. Trouble is he has lost faith in it and is thinking of selling, Paid out lots last MOT for drive shafts, I think. I have tried to say, "why sell it now, what else can go wrong?" But it is a very different car to drive now. Many thanks for all the help. I was quite envious when I got out of his Range Rover into my D22 Nissan!!!!!!
