Hi is this petrol or diesel?

Most likely cause is one of 2 things, EGR valve Exhaust Gas Recycler or The air mass sensor

the EGR valve basically resends unburnt fumes back through the exhaust not dissimilar to a small turbo in its function and kind of does the same job on a smaller sacle. Quite often though they do not fail completely they just get dirty, you can remove this part your self and clean it with carb cleaner, do not use anything else but carburetter cleaner. you will notice inside the EGR is a small sensor very much like a small diode, spray this and clean the whole thing as best you can. be careful not to touch the sensor just use the spray for that part. then leave to dry naturally, shouldnt take long.

When these go or get dirty the car will feel really powerless, you might get 50 mph if your lucky maybe 70mph. they struggle on hills and you need to be in low gears all the time to get anything out of the car, also the light comes on. They cost for this model between £180 and £250 so its well worth trying to clean it first as this is most commonly the cause of failure.

the only other thing it could be would be the air mass sensor, again you can clean these but to be honest normally when these go you will have to buy a new one. unsure to clean all the connetction / wires to both parts also and ensure they have a good contact.

a new air mass sensor is under £100. if you need more info on these parts please get back to me.

2003 S-Type Jaguar

First step is to drive to AutoZone or Advance Auto Parts carefully, without heavy acceleration. Tell them you have a check engine light and you need the computer scanned. They'll do it free (a dealer will charge an hour's labor even though it only takes a few minutes). Ask them to give you a printout of the codes, and post them here. Do that as a reply to my post and I can help you decipher the codes as to what they mean and what needs to be done. Was the car sitting in water deep enough to touch the bodywork, or were just the tires touching water?

Go to Auto Zone and ask the to run a diagnostic with their OBD-11 computer. This may still be a free service. Write down the error code/codes displayed. This should help pinpoint the correct sensor.
