Hi there, hopefully I've posted this in the correct place; been ages since I've been on here and even had to reset password :D
I'm hoping that someone with more experience of XFs might be able to give me some pointers. Having looked at previous posts I could be looking at intercooler failure, intercooler hose, inlet manifolds or secondary turbo actuator pivot seized.

So, here goes; Wednesday. I'd just come off the M25 and onto the M11, opened her up and felt a hesitation as I accelerated. I knew what was coming- a red 'restricted performance' warning. Hoping it was a glitch I stopped at the next services, locked the car, grabbed a coffee and hoped it would reset on restarting. Alas no. So drove all the way back to Peterborough on restricted performance.

Yesterday I checked for fault codes and was faced with the following:
P2263-22 Turbo/supercharge boost system performance.

10 miles later a second code was logged:
P006A-00 Manifold absolute pressure- mass or volume air flow correlation.
This code I would assume is a result of the first code and problem as the ECU has noticed that the reading from the MAF is not what is expected.

Probably totally irrelevant but maybe not, 10k miles earlier two codes were logged at the same time, P22D3-77 Turbocharger turbine inlet valve stuck closed, and P22CF-71, Turbocharger turbine inlet valve control circuit- Open.

Having cleared the codes I took her for a run today to see what would be logged and the only code which came up was P0006-00 (MAP)
Needing to nip to the shops I reluctantly drove her and this time the engine management light came on as well as the restricted performance message. When I returned I checked the codes and had the following:
P0006A-00 (MAP) this code now has a indicator next to it denoting that this is what has caused the engine management light to be illuminated.
The second code is P2263-22 Turbo/supercharge boost system performance.

I'm still thinking that P0006A-00 is a code resulting from the problem and the cause is whatever has resulted in
P2263-22. Seized actuator maybe? I had to do the other actuator last year, the one mounted just in front of the crank pulley as the pivot on the arm had seized solid.

So, before I start stripping down tomorrow, any advice would be appreciated, thank you.

The inter-cooler inlet seal is another known weak point that will bring these errors up. If you get someone to rev the car & listen (under bonnet) in the near-side front area. If the seal has gone you will hear pressurised air leaking out. You may also be able to see if the seal has pushed. Fortunately this one is only a few pounds to fix.

Thank you, I’ll check the inter-cooler seal once I’ve built her back up if I’ve still got problems; new manifolds just arrived.

All sorted, it was the manifolds. Absolute a*se of a job :D
Big mishap with the oil filler neck; didn't want to come out of the old manifold and in the end I had to resort to grips. One of the lugs broke in the old manifold but that was okay. Plenty of rubber lube and fitted in new manifold. Unfortunately, both lugs in new manifold broke and so superglue and epoxy weld was needed.

Respect - I've read before what an awkward job this is.
What was the worst bit - getting injectors out?
