Learning a lot catching up on this thread however, not sure exactly what but I'm still reading.

Right guys, I have done my best to separate the two threads and created a New suspension thread for Jsedita74.
Hopefully I got it mostly correct and we are now back on track with two different threads.
Some of you will note that you have had maybe one or two posts deleted, this is NOT punitive action, but was purely because that after the move they were irrelevant to the thread.
I hope this helps, and that jahummer can soon provide a 'happy' update.

I don't know if this is of any value, but since I will be too busy probably for a few weeks more before I can visit the other Jaguar tech, I tried something else.
At a stop, in drive, motors idles at 600 RPM, increasing RPM only makes vibration worse. Sometimes I notice RPM drop to 400 when I roll to a stop and motors shudders but recovers to 600 quickly. Vibration persists with or with out AC or other loads. Any additional loads just make it worse.
In neutral, increasing throttle introduces similar if not same vibration @ 1200 RPM, gone at 1400, back at 2600.
FWIW

Update
Met with a Jaguar tech today. Did not tell him too much. AS soon as he started the car and shifted to reverse, he observed an abnormal vibration as well the noise I have mentioned here before. He took it for a test drive and believes that it could be the transmission or torque convertor.
Any thoughts?

Transmission -- 10%
Torque Conv -- 35%
Flexplate -- 55%

Car is going back to the original Jag dealer on Tuesday to have ALL rear suspension components replaced under warranty (when I changed the rear rotors and pads I discovered all the bushings were shot and leaked and I do mean all), why they didn't notice this in November boggles my mind.
Anyhow, they would like to "double" check the motors mounts and transmission components.

Jaguar still can't figure it out but now they think the noise is from the super charger and within spec.
They do feel the vibration and shudder but cannot pinpoint it. Of course WDS says nothing.
They think there may be dirty injectors and run a cleaner though the fuel
System for $150.

I will say this, as far as fuel system or injection cleaning goes, for maintenance type service we use BG products. For diagnostic or corrective injector cleaning in house, if fuel trims are high positive, we use Valvoline SynPower run directly through the injectors. If the trouble is beyond the scope of that type cleaning, we pull the injectors and send them to Linder's Fuel Service here in Indy to be cleaned, flow tested and balanced. That's the ultimate repair, and Linder is known nationwide as the best in their business.
I don't really like knocking products, but we were talked into using Wynn's injection products some time back by a supplier. Those of us that do diagnostic work made mgmt. throw them out and get us SynPower back. It just didn't work. We'd run the stuff through the system and saw virtually no impact on the high fuel trim problems we were trying to address. The BG stuff works rather well for maintenance use, running it through the tank. It may have been you I recommended it to some days ago.
Just a few thoughts........

I very much appreciate your feedback, as always.
The dealer is still stumped but agrees something is not right. I do not fault them because I do not think they have ever encountered such a thing before.
I did speak with the advisor about doing a proper cleaning but he said it was too cost prohibitive to disassemble everything to pull the injectors. OF course he claims the Wynn product works great but does not guarantee it.
If I do not get this sorted out before then, I will be up in the Cincy area in May and would try to meet with you.
Otherwise, unless an obvious failure occurs, we're still tilting at windmills to a degree...

Service advisor left a message this morning. They performed the injector flush yesterday and claim it has solved the problem. Of course I have not driven it yet, but we'll see. Waiting on warranty inspector to come today to approve replacing the rear suspension. All of the bushings are dissintegrating and leaked but Jaguar thinks it won't be covered by warranty as the bushings to them are considered cosmetic.....

I presume that he also thinks that things such as springs, door handles, parking brakes, lights, air conditioners, & alternators (just to name a few) are also 'cosmetic'?
I know what I'd be telling him he does with his mother if he pulled that one on me!!
For my money, they are mechanical components of the motor vehicle essential to the normal use & enjoyment of the vehicle being the purpose and reason for which you purchased said vehicle (jj, help!!).
Non- Bast-ardium Carborundum (take the hyphen out & re-read) - very bad Latin for "Don't let the Bast -ards Grind You Down" (sorry 'bout that, but the system will blankety blank the written word otherwise, and the expression from my Air Force days loses its effect)
Cheers,
