Having a restoration shop and running several newer Jaguars I have seen similar situations. Intermittent multiple errors such as these can be caused by a low battery (or corroded connections) that "fool the computers". Also had a '99 XJ8 VDP have exactly the same issues over several months. Issue was a manufacturing fault in the sensors on the throttle body that caused the "limp home" mode - usually in stop and go traffic. Jaguar had an inspection and recall on the throttle bodies but that vehicle had gone through 3 different Jaguar dealers for service and none looked at TSB/Recall or performed the necessary checks on the throttle body. Tried cleaning the throttle several times (per Jaguar TSBs) but no change. Had to replace throttle body & problem solved (over 30,000 miles since then). Recommend making sure all air connections to throttle are clean and open and cleaning the throttle area to see if that helps.
On newer Jaguars (and other Al bodied cars) similar problems occur when the "ground" connections to the body become poor (usually through corrosion but sometimes through collisions). Connections may look perfectly normal but have high resistance. Careful when working with the connections - the posts are usually very loosely fastened to the bodies. The engine quit on a 2005 XJ8 VDP when I turned the wipers on (fortunately I was driving slow in a parking lot) because one of the forward bulkhead ground connections was corroded (looked normal but separated from body when removing the wires to clean them).
Also there occur occasional funny intermittent issues with all newer Jags that seem to be untraceable and non-reproducable computer "glitches".Good luck.
great answere!

most likely the ran it up on the lift and that triggers all these. you should be able to bring it any local garage and they should clear it.

When this happens, usually you have to replace the Computer. There is a chance you just didn't reset it when you took to cables off. Remove them and tape or hold them together for 5minutes or longer. If it still does it, I would get a book and find out where the code is to lead you. With the obd it only gives you a starting point in the diagnosics. You may have air in your lines that need bled, a sensor out, or just plain adjustment of the cables. But it shouldn't go into limp home mode unless you lost your Engine Control Monitor. Oh, I didn't click the read more button. Check the E-brake cables. You may have run over something that hooked it and ripped it loose. The Jags can tell if the cable is too far out of adjustment. It's under the car, cable should go through the floor and run to the rear of the car and Y out to the rear wheels. Good luck.

You need to go to your local auto electician,to plug in scanner
This will locate fault before it gets worse

MOST TIME LIMP MODE MEAN ECM FAILING IF YOU CANT ERASE OLD CODE AND REPROGRAM ECM. AND IT CANT RELEARN NEW PART ECM HAS A MEMORY FAULT.
