Failure to lubricate the TURBO control DIAPHRAGM linkage can cause severe wear (to the linkage), and result in the DTC P2263. Neither the diaphragm nor the linkage can be purchased separately. I have no idea what conditions, nor how much mileage, would cause the wear shown in the pictures in the following link.

post #78, #95-104 for pictures of the diaphragm and control lever.
Now that you know what the parts look like, the diaphragm is located on the passenger side of the turbo air-pipe into the intercooler, and behind and below the intercooler. The linkage pivot point is located about 1/2 inch from the turbo air-pipe, directly below the diaphragm, and between the air-pipe and the turbo body itself.
Remove the intercooler shroud, and you can easily see both the diaphragm and the linkage/ connector as shown in the pictures in the link above.
WHICH LUBE?
It is not that difficult to lubricate the linkage-pivot point with a spray lube. But what to use? I first considered motorcycle moly-type chain lube. The only data I could find said the DuPont brand is good to 300F degrees.
I decided to use Super Lube, which is good from -40F to +450F degrees, in an aerosol can. This is a PAO synthetic with Teflon. For more information on this lube, and availability, see this link:

HOW TO APPLY THE LUBE:
For those who have lubricated a motorcycle drive chain, you already know what to do. For others, more is not better. The turbo linkage pivot point is (hopefully) still a very tight fit. Apply only enough lube to seep into the joint, and no more more will only attract dirt.
If dirt seems to gather at the joint, the next time, use some WD40 to wash-and-clean the joint, then allow to air-dry, before applying new Super Lube. WD40 is a penetrating oil, not a lubricant.
Its best to apply the lube with the engine cold, and wait at least overnight for the lubricant carrier to evaporate, and the lube to set-up/ thicken, before driving the vehicle.
I would suggest lubrication every 3-4 months, depending upon miles and vehicle usage.
