OP may be busy trying to work the problem out, or as you suggest, its just a "woe is me" post.
I sure hope not the latter because there are a lot of members offering valuable support information.

Thanks to everyone who has chimed in. I'm still monitoring this thread but don't have anything significant to report yet. While I have extensive contacts in the BMW community, this is the first time I've had a Jag which required major service. I've been speaking with local Jaguar specialists to try to decide who to take it to.

Our collective experience tells us its an injector.
Have them all cleaned anyway.
Here is a local and a mail order.

@pwpacp, so far I've spoken with:
Vance @ Enzo's Automotive in Marietta
Randy @ Kuhn Auto / Cadillac & Jaguar of Northlake in Tucker
Sandy @ North Point Motors in Roswell
Trish @ The Shop in Norcross
Ryan @ Road Britannia in Buckhead

Please let me know by post or PM if you've had any experience with, or heard any feedback, regarding those shops. I'd certainly appreciate it!

Have you considered buying a cheap OBD code reader & reading the codes?

If it is injectors and/or coils that will tell you.

I had the car towed to a specialist repair shop this evening. While I was waiting I used my new scan tool which read the following codes:
  • P0300 - random multiple misfire detected
  • P0302 - cylinder 2 misfire detected
  • P0304 - cylinder 4 misfire detected
  • P0306 - cylinder 6 misfire detected
  • P0500 - vehicle speed sensor A
  • U0122 - lost communication with vehicle dynamics control module
  • U0402 - invalid data received from transmission control module
  • U101B - lost communication with GSM multiple bus
  • B1087 - LIN bus A
  • P1707 - transfer case neutral or park / neutral indication circuit (I had pulled the manual override to engage neutral)

Yep definitely sounds fixable, and you were all worried it was going to be "Fatal" Good Luck.

+1, injectors. I believe there was another thread somewhat recently with much the same indications on a 5.0l xk.

For those of us who have had similar experiences, it was an injector in each case. You'll be fine.

Hey community,
This is so avoidable. Rest of the world knows you cant drive a directed injected car without cleaning the injectors.
Religiously use PEA based cleaner.

I think you forgot to mention P0308, cylinder 8 misfire detected. I am most assured that it was there.
As others have said (me as well), one of the injectors is faulty and stuck open.
Reasoning; one injector open will prevent the OTHER injectors on that bank from receiving the full fuel pressure from the High Pressure Fuel Rail on that side, therefore an insufficient quantity of fuel for those three cylinders, causing the misfire. The STUCK injector will also have a misfire due to TOO MUCH fuel.
That's what happened in my case.
Stick your nose into the oil filler tube on the valve cover..... it'll probably smell of (a lot of) fuel.

The extraneous faults are probably gremlins (TCM, VDCM, GSM) due to 'sitting there' and a low(ish) battery.

On a car that is a decade or so old, that you didn't own from new and religiously maintained... I am not so sure this is avoidable.

Also, this would be a good time to drain and clean fuel tank, change fuel filter and run cleaner through the fuel system. Old fuel turning into varnish is common cause of such types of failures.

It's early yet, so I have yet to hear from the repair shop. I've owned this car exactly a year and in that time I've driven it about 8,000 miles; this is the first drivability issue that I've ever experienced with it. I'm not familiar with direct-injection engines. Are there any common issues to be aware of, or recommended maintenance other than injector cleaner?

Direct injection engines are also prone to two types of failure unique to DI - a) intake sludge and b) timing chain wear.

a) Unlike BMW and Audit horror stories and walnut blasting becoming a routine maintenance item, Jaguar doesn't have severe sludge issue. Still, you have some blow-by oil, and you have no fuel washing over intake valves. Some sludge will form. On my car I do regular chemical intake cleaning so I don't end up having to do walnut blasting.

b) DI engines tend to wear down timing chain due to carbon micro-dust. This can be largely mitigated by more frequent oil changes.
