Recently bought this 2011 4.4TDV8 137k miles.
Restricted performance red-light (mostly does not throw EML)
Codes read that seem significant..there's others related to doors and amplifier sound system
P0486-17 seems to be the active one and the one restricting performance.
I have ordered a replacement throttle body as this code seems to have been cleared a few times by others here. The association with the fault code seems convoluted however it has been recorded a few times.
I also have 4 boost hoses to change
Both air filters
I cleaned the MAP and sensor inside the throttle body plastic connector.
Apart from this annoying issue the car is awesome to drive.

New throttle body fitted new air filters fitted That seems to have resolved the restricted performance issue for now.
Will have a look in the old part at some point.

Right now just glad to be able to drive a few miles with a bit more confidence.

Be good to see if the gears have started to stip in the throttle body.
Seen a few pictures of ones that had. Might be a future fail point.
