Started with no error messages detectable via IID Tool before things getting worse and moving through a series of different error messages:

P006A-00 (27) Manifold absolute pressure - mass or volume air flow correlation

then a few others and finally this one:

P2263-92 (27) Turbo/superchage boost system performance - Component failure - performance or incorrect operation

I started to suspect it was the turbo actuator problem that his the subject of the Technical Bulletin LTB00504V3.

The VIN is definitively in the range shown in the bulletin and I think the photo below shows the existing actuator to be the old version with the nut on the top.



Has anyone else had this replaced under warranty? Any thoughts?

The whole unit on mine was replaced under LR Approved warranty, but it is seven years since it was done.

The issue is caused by external grime etc. A good clean and lubrication with a spray cleaner working the actuator by hand should free it.

If they've issues a Technical Bulletin on the problem does that mean that I would still have to pay to have it replaced with the latest version or is that something Land Rover would cover? Obviously given the age of the car there is no warranty on it.

A TSB just gives a diagnosis & fix for specific issues, they are meant to 'short circuit' what can sometimes be a lengthy diagnosis path and prevent mis-diagnosis. It doesn't infer any post-warranty period liability, that is generally only safety recall territory.

Personally I would remove the nut temporarily , get plenty of penetrating oil on it and get it moving freely up and down the spigot. You have nothing to loose, worse case scenario you will have to replace it.

The sticking could be at the butterfly spindle so don't just clean and lubricate around the nut - be liberal with the cleaning spray or fluid.

P006A is usually associated with a boost leak...

Any idea why this part is described as a Compressor Shut Off Valve (CSOV) (part # LR033284) when it appears to be the turbo actuator?

Which would make the others consequential DTC's - as Mikey highlighted, best to check for charge air leaks first.

Do these photos look normal? Not sure about the vacuum hose that connects to the valve.

If you have a suitable piece of hose, pull the hose off the actuator and attach the new long piece and give it a good suck. Actuator arm should move by 90 degrees and close with a good 'thunk' when the vacuum is released.

I have never tried this, but if you have got a draper oil suction pump, you could try connecting it to the hose and see if it moves as you build up pressure.

Bear in mind I was told the reason they fail is because they only move a small amount and seize up when clogged with road grime, particularly salt.
