Can the actuators be checked, cleaned, removed and changed if necessary, and if so, where are they located? Are they part of the turbo or inline in the system somewhere?

I'm sure ours has the modified arm thing on for the turbo.

Isn't there a test function for checking the actuators in the GAP IID tool? 2012 TDV8 Vogue (L322) |

Ok, so after many hours removing and checking pipes I didn’t have any luck finding any splits.

oh, and I should add - my pipe at the front feels like your description - about 2mm of play and feels loose. 2010 L322 Autobiography Black Edition

It's also possible that one of the hoses is delaminating and causing an internal restriction, this gives a low boost reading but no external leaks - they're a bu88er to find and usually occur on sharp bends, but not always. Look for any scoring on the inside or a misshaped hose, sometimes you can feel a soft spot from the outside or there will be an oily patch on the exterior that you can't attribute to any leak or spillage...

I completed replacing the four rubber boots on the intake this morning. The rear right definately had a split in all the way through in the middle.

I’m still not finding a split or damaged pipe anywhere.

Have you checked the intercooler for damage? usually shows as an oil stain.

Nothing obvious on the inter cooler but that said I haven’t removed it.

I couldn't really say - it's a bit hit & miss as there isn't really a consistent diagnostic path being followed - most likely because you don't have access to smoke tester, reliable pressure measurement equipment etc. The raw voltages don't really help as they're not being mapped to pressure values - I appreciate that the lack of change indicates something, but unless you're looking with a wider view at other signals and their plausibility in relation to the one causing concern, it's always going to be best guess without a frame of reference. |
