Amber gearbox light came on in my 2004 S type Jaguar. After shutting engine down and cooling it started with no light on. So, I limped home. The Q: Now that the light is no longer lit can I drive it? Or, just take it to the shop for repair?

When the limp home is engaged by the processor a fault code or codes is set in memory, it may be a Transmission code or engine fault code. You nee it tested with a full function scanner, a code reader will not read the transmission faults.

If it's something electrical you can try to reset the computer in in and see if that works. I do this by disconnecting the battery for about an hour and my cars are reset. Good Luck.

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.

change yor air flow sensor

If the light stays on when your moving that shows a problem....I think that what your seeing is the computer testing the verious curcuits as its programmed to do

i have problem jaguar x type 2004 when many time motor is start the ligth amber turn on and massege engine fault problem.next the engine do not acceleration

The only thing that will cause a cruise control fault is a loose vacuum hose ussually on the breather hose coming from the valve cover in front to the throttle body. As for the remainder, shut off the car and restart to get you home and avoid the limp home mode. That in itself is an electronic fault in the ground system. Check you coils or replace them with a new set of plugs (autolite double platinum recommendes.) Clean any grounds you may have and then start you engine. You will notice there is no problem then. Run a diagnostic tool to see if there is any fault with grounded sensors like the O2 to keep that from happening again. Don't get the tranny replaced cause thats all the dealership wants to do and charge you $5k. Its not the actual cause. Good luck and let us know if there is anything else we can do here at fixya.

You need to take to Jaguar technician to have Mil lamp codes read and cured the restricted performance is the engine protecting itself as there is a fault in the management system,usually fuel system related,It has gone into "Limp Home" mode to try to limit the damage done untill the fault is cured

Sorry late reply - just seen this problem. The amber warning is basically saying a problem developing. The red and limp home action is showing more serious developement - But not always very bad news. Had car with same symptoms and it was a faulty sensor on engine, and another similar case was throtle position sensor. Get the car to a garage that can read the faults - so you know what the problem is that has been registered in the memory.
Hope this helps

I have the same car, same problem and I've been doing some research. It seems to be that the most common problem is a faulty ABS sensor that causes the car to go into "Limp Home Mode". Limp Home Mode is automatically initialized when the car senses that it has some sort of electrical or mechanical issue. This is most likely what your experiencing, because I, and many other X-type owners are as well. Good Luck.
