My mother took a shine to my old 2010 3.6 TDV8 and it now lives a quiet life up on Skye. One day I got a WhatsApp to say it is a little out of sorts and there is a message saying restricted performance. Oh no…turbos was the initial thought, the local garage even went as far to say it needs to go to a main dealer for that and the bill would be more than the car is worth. Hmmm….

We were heading up for Xmas so in went the ramps and the long nozzle wd40 and the borescope and the code reader….. One quick data log showed the left side (UK passenger) actuator was stuck. DiscoMikey (Mike Park) helpfully and remotely said the code P132E-22 (2F) Turbocharger/supercharger boost control B performance - General Signal failure is usually just the actuator sticking and not a duff turbo.
Up on the ramps it went in the middle of Storm Gerrit and with a few well squirts of the motion lotion and a manipulation of the actuator rod using some thin curved rebar, the actuator freed up and moved freely during the start up and shut down cycle. You can just get to the rod through a hole in the subframe pictured below. Hope this helps one other person out 👍

A nice test drive across Skye confirmed it was working well and providing healthy boost again.

This is something I must do to my 4.4 TDV8 before they get stuck, will have to look up the forum and see where they are located. The new WD40 cans with the bendable nozzle could be handy for this work! Current yokes

Shouldn't be an issue on the 4.4. The only similar system that can get stuck is the turbo diverter valve but as yours is a 2012 it will be the later type which doesn't seize. 2012 TDV8 Vogue (L322)

The new metal nozzle does make it a little more doable, you still get excess wd40 over parts but for the most part it makes hitting the target a little easier. 2002 L322 4.4V8 - G4 Challenge Car - Australia leg

Another reason I boot my 4.4 TDV8 on every drove when it’s warm.
Secondary function is to reduce any oil build up.
Great story this btw. An old bit of bent bar saves the day. Brilliant  Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Thank you for posting this. I have just recently solved the same problem with the driver's side actuator sticking. Fortunately, the (UK) driver's side actuator is a lot more accessible, though it is also a lot more exposed to water and road grime. I was wondering how I was going to get at the passenger side actuator if that became a problem too... many thanks!

No problem U1, hope it helps and yes the drivers side is so simple to get to! 2002 L322 4.4V8 - G4 Challenge Car - Australia leg

I do wonder how many people have been stung with turbo replacement jobs when a bit of oil on an actuator was all that was actually needed. I was fortunate that a previous Performance Restricted issue was identified as a sticking actuator by the local main Land Rover dealer in Dungannon. They just oiled it and let me know what the problem had turned out to be. When I had a recurrence of the warning light, it was the first thing I thought to look at, and right enough, that was all it was. I think next time I crawl under there I'll stick some silicon oil on it rather than just WD40 though. A Brace of Bronze:

WD40.. The ' WD ' stands for 'Water dispersant'. It has very limited and short-lived lubricating qualities.

Very true, but the long metal nozzle is perfect for directing it where you want and it’s the physical manipulation that frees it up. The motion lotion is only a short term aid and that’s all that’s required.
A longer term solution would require more access and a lubricant with little or no flash properties, but silicon spray won’t remove light surface rust like wd does. 2002 L322 4.4V8 - G4 Challenge Car - Australia leg

Anyone have any pictures of the 4.4 linkages that could cause sticktion? Reading around vacuum hoses can cause similar faults
