Its possible one of the two rear hoses are damaged. Ive heard these are a pain to replace. Another less likely possibility is one of the two 90 degree hoses on the top of the motor. ______________________________

I tracked down my similar issue eventually to a poor connection between the O/S MAPT sensor and the plug on the loom. Was able after fiddling for ages to increase the clamping on the connector receptacles in the plug. Also, as the sensor pins are tapered, I ensured the plug is fully home on the sensor by holding it there with a small cable tie around the plug and a local vac hose that runs near the sensor. No issues with this now for several months. Previously a 2008MY Tonga Green Vogue SE 3.6 TDV8

Ok so I have made a smoke generator and checked everywhere for leaks.

Couldnt find any boost / vaccum leaks.

Must be a sensor or mechanical issue?

That’ll save the pocket!
Mine was down with split manifold! And you’ve got to do them both  2014 vogue se

Had a specialist check out the car. MAF readings all normal so that can be disregarded in the diagnosis.

The specialist has driven the car and reckons the turbo actuator is sticking on the passenger side.

He said its impossible to gain access without dropping the engine/subframe? Down.

I have read about people checking and lubricating these from below but there is no clear explaination on where to look to see the actuator.

Any suggestions (passenger side actuator N/S, TDV8 RHD)

It can be done without removing anything. Depends how stiff it is I suppose.
There is a post on here where the chap made a hook to pull it and work it free. Do a search for it.
Plenty of Wd40 and patience and a ramp is helpful.
Its located above the front diff.

Thanks Grofus,

Tried out a new gadget today, my usb boroscope.

This allowed me to get right up to the actuator and find out that it moves freely without sticking.

So that isn't the issue either!

Loosing the will a bit now

Just because the MAF readings are normal doesn't mean they're truthful. Can you start swapping MAFs from another vehicle?

So, you have ruled out turbo and hoses, cracked manifold, turbo actuators, map sensors. Trans adaptation reset done.
Injectors!!!! How does it idle out of drive? How does it rev up out of drive? Faulty throttle body or sensor!
I would get it on good diagnostics, i know you have SDD. So do I and im not a fan.
Its gonna be something simple and irritating when you find it. Maybe your remap data has been lost or damaged. Get the company that did it to check and reflash it. 2007 Vogue TDV8 in Zermatt Silver with Charcoal

I have been there believe me on this issue when you talk about losing the will to live! The fault code relates to the boost side of the turbo so the MAF sensors (just next to the air cleaner box) are not involved. You could try swapping the MAPT sensors in the inlet manifolds and see if the fault swaps sides. That's a 10 minute job. One plug and one screw per sensor and just pull them up and out. Also check if the left one (bank A) seems to be crudded up with oil etc. Clean with brake cleaner but don't get cleaner up inside the sensor as you might damage it. If the fault changes to bank B that is the problem. Replacement sensors are about £50 each IIRC. Previously a 2008MY Tonga Green Vogue SE 3.6 TDV8

Hmmm. Rereading thread my post may be superfluous. In fact my car did not have the erratic tickover and slow pickup below 2500 rpm you described so I suspect a different root cause. I'll get my coat! Previously a 2008MY Tonga Green Vogue SE 3.6 TDV8

You may find error codes are revealed by different diagnostics tool. Like many I bought a GAP BT IID tool and would be lost without it. Previously a 2008MY Tonga Green Vogue SE 3.6 TDV8

Ive tried fitting a new maf to replace the one which i thought was reading low but no dice. Tried a combination of the 3 mafs I had to hand and nothing no difference.

Car idles and revs up perfectly out of drive.

I could get the remap checked but it has been fine for months until the boost hose split.

The RR has never driven the same since the hose split. Perhaps the passenger side turbo has been damaged? There is nothing to suggest this though.

I am fed up with it now. If anybody lives near manchester and would be willing to attempt diagnosis ill happily drive it to you!

Thanks everyone

Again, I would check the 90 degree hoses and short rear hoses. The are not shown clearly in this workshop diagram, but the rear is located near the 12 and 90 degree is coloured green along with sections of plastic piping.

There’s also the bottom hoses, particularly on the side mechanic said had stuck actuator.
