Hi Don,
No, it never resolved, and I have done alot of driving since my original post. I got busy with work, so I have not been back to it, but will have to soon as my smog test is coming up! I almost suspect the ECU at this point, but have no data to support that suspicion.
Do you have any other ideas?

After conducting several different diagnostic drive cycles, I finally got this '03 X308 to flag P1649, which IDS says has to do with a flash memory problem in the ECM, and the DTC Summaries Guide says indicates a problem in the ECM to DLC circuit, either a short to ground or a short to B+ voltage. So my next step is to investigate those circuits before swapping in another ECM.
BTW, Torque Pro can read some of the Mode $06 data and it indicates that Tests $0a and $22 are not completing because the components are out of range. TID $22 has to do with the EGR but I haven't found the Jaguar documentation for TID $0a yet.
Has your car flagged any codes other than P1000?
I'll let you know what I find.
Cheers,
Don

In addition to the above, my car also shows:
TID: $22 CID:$11
Max 37,683
Current 65,535
After performing three different diagnostic drive cycles, Torque Pro now shows "FAULT PENDING" along with the P1000.
IDS shows the P1649 code along with P1000, but after more research I'm beginning to suspect that the P1649 is just a spurious code, perhaps from connecting and disconnecting three different scanners multiple times today. I suspect P1649 is not the reason the monitors are not completing in order to flag P1111.
I found some Mode $06 data on pages 12 and 13 of the attached DTC Summaries Guide.
JagV8 mentioned somewhere that the TOPix website has some Mode $06 data so I'm going to see what I can find there.
Cheers,
Don

Update: I found the reason that P1000 would not resolve to P1111 on our X308.
As I was giving the engine bay a careful inspection, I discovered that one of the two mounting ears that secure the air intake pipe to the throttle body had broken around the head of the screw, allowing that side of the pipe to be just loose enough to create a small air leak between the end of the pipe and the rubber seal.
I added a large washer under the head of the screw to re-secure the pipe, and when I scanned for codes a few days later the magic P1111 had appeared.
Now I can get the car through emissions testing so I can get it licensed. Yeah!
smtguy,
Since the Mode $06 data on your car was very similar to ours, it would be worth checking for a small air leak in your intake plumbing.

Don

Hi Scott,
Yes the snorkel, part 5 in this diagram. The lower end connects to the MAFS and the upper end connects to the throttle body. You can see the right mounting ear in the diagram. On our car the left ear had broken through around the head of the screw (7) so the joint between the end of the pipe and the rubber seal (6) was no longer air tight.

JagV8,
Great question about the fuel trims: they were the clue that led me to search for a small leak. LTFTs were B1 10.9 and B2 14.8. I haven't measured them since re-securing the air intake pipe but will be surprised if they aren't lower. I also won't be surprised if there are other remaining issues. For example, I think I'm hearing a slight exhaust leak on B2 (from the driver's seat - I haven't listened in the engine compartment yet).
Cheers,
Don

Hi Charles,
I would like to tell you that my XJR passed the P1000 code to reset, but unfortunately it has not. Since I have aftermarket cats currently on the car I, am going to change to the stock Jaguar cats and 02 sensors this week to see if that makes a difference. It seems like I have done everything else.
I am keeping my fingers crossed at this point, and I will post the results.

Hi Charles,
I don't know if you saw my posts #28 and #31, but I was able to resolve this issue on our '03 XJ8 by tracking down a small air leak.
Cheers,
Don

White XKR,
With Torque Pro I am getting:
COMPONENTS: INCOMPLETE (See first post in thread)
which leads to:
TID $0a CID:$11 NOT OK
Sensor period
Max 33,423
Current 65,423
Since I have no idea how to interpret this, I also have no idea what to do about it. All I can think of to do is change back to the stock cats, and try some new 02 sensors.

Scott,
If you haven't done so already, you might try monitoring Short Term Fuel Trims (STFT) with Torque while, with the engine running, you aim an unlit but open-valve propane torch along every part of the air intake, intake manifold gaskets, fuel injector O-rings, breather hoses, vacuum lines and EVAP components that you can access to see if the STFT shifts rich at any point.
Starting fluid or other flammable spray can be used as well. I've never had a problem with these methods, but it's smart to keep a fire extinguisher on hand (or even a garden hose) just in case.
If you know an independent shop with a smoke machine, that's a great way to find the smallest of leaks. You can actually make one for less than $20 - search YouTube.
Cheers,
Don

this is the only X i got from torque pro diagnostic.
Originally a fault had shown engine running lean, & check gas cap, but a refuelling solved that issue. So now, all i have is P1000.
Thank You All!
