Question about 2003 Jaguar X-Type
Filled my x-type dielsel with fuel and travelled back home for 19 miles. the following day after a raining night took the car for a short journey, but the car felt slagish, second and third gear would not go more than 30pmh, and on the motorway would never travel over 50mph with full throtle

First question: Is it possible you put gasoline in the tank by mistake instead of diesel (or that gasoline was added to the wrong tank at the gas station)?
If not, then suggestions:
--Maybe an electrical sensor or connection got wet. Open the hood and let everything dry out for a few hours, then try again. If that fixed the problem, check all electrical connections for areas where water could penetrate, and repair/replace as needed.
--Borrow a code reader from an auto parts store (free) and check to see if there are any trouble codes (fairly easy procedure). Then look 'em up online.
--If your problem isn't the wrong fuel or wet connections, I think the likeliest cause is a bad crankshaft or camshaft sensor. When one of those fails, the computer often has a "limp" mode that will let the engine run, but at low RPM.

It sounds like your Throttle Position Sensor (TPS); located in the throttle body. (Diagnositic test may point to alternator or TPS; I experienced the same issue and although replacing an alternator is easier on the pocket book, it doesn't correct the problem; which will get worse.)
(My story) The amber transmission light would pop up; after a restart, it'd go off. Eventually this led into the engine dropping into safety mode (15-20 mph); while driving city/highway without fail everytime; inbetween driving distance became less and less. (prior to this I had taken my car in several times; each time they reset the computer and $$replaced my alternator, as suggested by my mechanic).
As soon as I drove it off the shop to my house, it dropped into safety mode; amber warning lights. Drove it back to the shop; had to replace the throttle body (the only way to replace a bad TPS). It can co$t anywhere from: $1700.00-$2,000.00 parts and labor. Shop around; because my shop diagnosed the problem part wrong, I got a deal (but it still cost me...). Since I had it replaced (April 2008), I haven't had a problem since. Jag Heaven (a parts company located in California) can ship parts anywhere; it was cheaper to do this than buy the part from my shop $aved $$$. Good Luck, hope this helps...

Probably those little Jag gremlins at it again ?
First thing to do is clear the computers memory, which normally does the trick.
Disconnect both battery terminals, switch on the ignition to start 6 times, this wipes the computer memory, and then reconnect the battery, the Positive + first......... then the Negative -----
Start the car and go from there.
Suspect you had a low battery previously, and this tripped the warning.
Get the battery checked, if it is the original, as it is now 8yrs old, and should be replaced.
Good Luck !
A FixYa rating would be appreciated Thank you !

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.

Are you loosing coolant? if so check for leaks. If you have lost a lot of coolant and then topped up your system it may be that you have an airlock, fill your system (when cold) and vent air out of the top engine water pipes, then warm engine up and check levels. Air locks can be indicated by the heater not blowing hot or the top of the radiator remains cool when engine has heated up. Also check the action of your thermostat. hope this helps - good luck.
