I could not work out at first how the control arm could be disconnected. Could not see what type of clip was used. Therefore I had already done two cleaning cycles before I disconnected it. When I did get it off it moved freely and as you said would move back under its own weigh. What ever the issues the car has, I doubt the turbo cleaning would have done any harm. I fact acceleration is improved and turbo responds is better. It's just the noise that is bothering me now.
I won't know if the limp mode issue is completely resolved until I go for a long run. Let's hope though.  Now at the point when I learn something new something old is lost out the other side !
Now retired so it doesn't matter anymore.

Ok, maybe the next step is to check the whole air path for cracks and leaks... Maybe you can construct a smoke generator and pump/blow in air and see where it seep out. Would sure make it easier.
Any suggestion on how to easily make a smoke device is welcome.

Thanks for the reply FL2Printzern
I have checked the full air path several times. I have also recently replaced all the standard hoses with silicone ones. It was after changing the hoses that the noise started? I therefore assumed the new hoses were at fault so removed and visually checked them again. No problem.
I then did as you suggested a smoke test.
I disconnected the air intake from the filter housing and used a smoke pellet ( used in the central heating industry to check the integrity of flues).
I placed the pellet in a metal container next to the air intake whilst the engine was running. All the smoke was drawn into the system but no leaks?
Problem is now I have this noise but no trouble codes anymore. Car still goes, just sounds like a bus.  Now at the point when I learn something new something old is lost out the other side !

This was strange... No fuel/exthaus smell? (leaking injector) What did you use to check for DTC's? (As your SDD didn't work) Have you tried to run it without the drivebelt? (Pully bearing or something.) Hard to know if the sound are mecanical or resonance from the air path...

Strange is putting it mildly.
I have a generic code reader which I had to keep in the car as originally the car would cough and jolt under load at 2000_3000rpm then go into limp mode. I could then pull over and reset the car to continue the journey.
I haven't removed the drive belt as I have had the car running whilst on stand's with the front wheels and inner arches removed and there was no noise. Its hard to reproduce the sound unless the car is being driven. It does appear to be a boost noise associated with the turbo but I can't find it.  Now at the point when I learn something new something old is lost out the other side !

Maybe this problem does not generate a DTC, but you don't know for sure before you have tried with a brand spesific tester. HawkEye with software v7 is very good and of course SDD...

You are correct, I do need to have this checked out on SDD. I'm going to have to make this a priority and fix the laptop so it may help me fix the car. I'll try and give this a go tomorrow. Now at the point when I learn something new something old is lost out the other side !

Just an update for anyone interested.
Looks like the turbo is failing on a gradual basis, hense the unusual noises.
Took it to a specialist turbo dealer today to have it checked.
Car has only done 46500 miles.
Will post back results.  Now at the point when I learn something new something old is lost out the other side !

Update on the car for anyone still following this thread.
The bad news is that it appears the turbo has been gradually failing, hense the strange noises.
Took it to a specialist turbo dealer (Turbo PAC) in Durham today. After a brief look I was advised not to drive the car anymore as the turbo was on the point of destruction.
Had to leave the car for them to take it out for a thorough inspection on Monday.
Considering the car has only done 46500 miles, not very happy.

Will post back results when I get them.  Now at the point when I learn something new something old is lost out the other side !

Yes, this was very early! What can be the cause of this? Is it the bearing? Wrong type of engine oil? Clogged turbo oil filter? (There is a small one it the oil pipe) How often do you change the oil? Keep us informed!

I don't do many miles in a year with this car, but when I do they are usually long journeys. The oil and filter are changed every 12 months and I use Mobil 3000 oil. I do now know there is a small mesh filter at the turbo but this is not part of any service schedule that I am aware of.
There has never been any smoke from the car and when I checked the intercooler and hoses there was no oil in there either.
The people at 'Turbo PAC' have some good reviews from other customers, therefore I expect they will give me an honest breakdown of the problem.
As soon as I know the answer I will pass it on as it may help others. Now at the point when I learn something new something old is lost out the other side !

didnt the turbo have some sticking rod issues? and landrover issued special high temp grease.if you find the problem please keep us posted very interested

please keep us updated ,very interesting post

Hi Peter.
Not much to update as yet.
Good news for everyone else. The turbo fitted to the Freelander 2 is very reliable according to turbo PAC.
The bad news for me is that because of the above, there is no reconditioned units to be had, therefore the price has just gone up to reflect the install of a new unit.
I would have done the job myself but no one would give me a guarantee on a unit if I did it myself.

I should no the outcome on Friday. Will post back then.  Now at the point when I learn something new something old is lost out the other side !

There is no problem with the turbo actuator. Don't know the answer as yet but the initial thoughts by Turbo PAC was that something was bent inside the turbo itself.
I'll know more on Friday and will post back.
Thanks for showing an interest.
