20 Most Recent 2007 Jaguar XK8 - Page 6 Questions & Answers

you have a fault with one of the wheels ,on each wheel is a sensor that picks up a mafgnetic impulse from a painted metal strip on the back of the wheel bearing ,using a obdii reader might pick up a fault on an american market vehicle but no chance on a euroepon model ,what you do is jack up each wheel in turn and then find the sensor connection block ,then connect a multi meter on lowest volt setting DC and spin the wheel and see if its producing a spike ,find the wheel that isnt then decide if its a sensor or a bearing ,find the right wheel then remove the sensor and connect to meter and pass a spanner over the head of the sensor ,if this works ok then its the magnetic path on the back of the bearing .Simple who needs a fancy diagnostic software reader

Me too ;)How can I help?

Overheating is problem, not codes. Codes only secondary from overheating.
Borrow cooling system pressure tester.
Replaces cooling system cap.
Pump up above cap pressure.
Watch that gauge does not go down.
If it does, then leak.
If you can't find it, try filling with coolant again, and over pumping.
Check for water in spark plugs from head gasket.
Run engine.
If gauge oscillates, then bad head gasket.
Always replace thermostat after overheating.
Make sure belts tight.
Charge battery.
If when you try to start, if voltage drops below 10, then either battery bad, start bad, or engine binding.
If it goes back to 12 when you stop cranking, it is not the battery.
If the engine is binding, it will not be easy to turn by hand, even with plugs out.

That is your check engine light, and needs to have a computer hooked to the car to find out what is turning it on before damage is done the the motor.

hello
if you locate the airbox fitted to the Right hand inner wing you will see a large black intake pipe leading to the centre rear end of the engine bay that is where the throttle body is located if you remove this pipe by removing the hose clip securing the intake pipe of the air mass meter and then follow the pipe back to the centre rear of the engine bay and the pipe is attached to the throttle boy with 2 10mm hex bolt once these bolts are removedand the intake pipe is removed the throttle body is evident

Sorry we can not give out radio codes. It is against company policy. You will need to take it to a dealership to get the radio code.

Yes you can use the trickle charge to keep the battery fit as it is stored up for such a long period. But at the same time the trick charging must be balanced or controlled not to over charge the battery . So if the charging unit has a cut off then it would be good as the battery will not be overcharged.
Hence you can try to get a good unit to keep your battery in trim condition.

Look under the hood.They will usually put terminals in there to jump start the vehicle and they go to the battery in the trunk.I checked the wiring diagram and it looks like the are some stud connectors under the hood.Hope this helps.Good luck.

Here is what the manual says you need to take off. Did you unhook everything in the trunk?

Remove or disconnect the following:

Negative battery cable Trunk liner Trunk seal retainer Rear lamp assembly interior trim finisher Left and right side liners Fuel feed and return lines Fuel filler and vent hoses Fuel tank wiring connectors Fuel filler cap Fuel tank retaining straps Fuel tank Fuel pump module

The boot ajar sensor is defective, it is a tiny micro switch that is in the boot latch, contact the dealer for a replacement part.

Hi! can you please clarify the problem. Is it not turning on when you hit the turn signal? Its got to be a bulb failure and you may need to replace this bulb for it to work. You will notice a blackish color on the bulb that indicates if its broken. Hope this helps, have a nice day

yes there is a procedure. get you car scanned at www.autozone.com you will receive the fault error codes.the error codes will indicate what is the faulty part.now at auto zone service center getting the car scanned is absolutely free. so you will detect the fault with no charge,you will just have to drive and take the car to nearest auto zone service center and get error codes.if you have no idea where the auto zone service center is then you can go to auto zone site get the details from them about the nearest service center of auto zone to you. This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

Hi.

Below diagrams for 1997-2006 fuse map. Click on the pictures to enlarge.

Due to maximum message length limit, I will post details on separate messages:

If the engine cranks normal, then the battery is good. You are looking at no fuel or no spark. Bad crank shaft position sensor or bad fuel pump or fuel pump relay most likely, could be other things less likely

Yes. Chances are, your fault code has been stored and will be able to be retrieved by reading diagnostics. They can then be interpreted and the fix...if necessary implemented. You may be able to get the codes read and interpreted for free at a national parts chain such as Advance or Auto Zone...they do this as a service in hopes of selling you the "fix" part or sensor. But Yes, It does need to be checked, and if you are money concious...(Like Me), take my advice first, before taking it to the Jag dealer and getting more than you bargained for! Good Luck! I hope you find this to be very Helpful!

My throttle body problem was diagnosed by the local Jaguar dealer (Barrett Jaguar in San Antonio, TX). They wanted $1200 to fix it. I had read on the internet that the throttle body should be cleaned out first because that could be the problem. When I asked them if they could clean it first to see if that is what is wront they told me that it would not do any good. It was an electronic problem and the whole thing needed replacing. I had my brother-in-law who is a mechanic clean it out for us and reinstall it. We have had no more problems. Can you believe I got a coupon in the mail yesterday from Barret Jaguar for a $143.50 throttle body cleaning special!!!!!! Liars all of them! Don't trust your dealer to tell you the truth! They just want as much money as they can **** out of you.

Here's what i have - hope it helps!

Probably your battery is bad. either charge or replace that and then learn the windows again. (have you got your radio code before removing battery?) to learn the windows do them one at a time with door closed. hold the down button you hear a clck a few seconds after it opens fully now hold the up/close button and again wait for the click. easiest is to hold the button pressed for 10 secs after the windo has fully traveled down then send it up and again 10 secs after it stops moving.

Hello Sir,
It seems that you are facing bad starter problem.You need to have a service of your starter. But before that make sure that the starter is the bottle neck of the problem you are facing. To check the starter you have to under go the following procedure:

Find the alternator (generator) and find the plug associated with the alternator. Find the black wire coming off of the plug. Connect a multimeter between the black wire (red lead on the multimeter) and chassis ground (black lead of multimeter). When attempting to start the car, what does the multimeter read? If under 11.0 VDC, then you have a bad battery cable, replace the cable between the battery and the starter. If the voltage stays constant with no change, then your problem lies with either a bad relay, bad wiring, or a bad solenoid on the starter itself.

If you think that you have a bad starter relay, interconnecting wiring, or a bad solenoid on the starter, you will need to move the red lead on the multimeter to the white/red wire on the starter (small terminal on the starter). Attempt to start the motor again. Does the multimeter jump to over 11.0 VDC? If yes, bad starter, replace starter. If no, then remove the starter relay (forward most relay against the fender on the passenger side of the car near the back corner). Now, install a short piece of wire between pins 3 and 5 of the relay box where the relay used to be. Does the motor turn over now? if yes, you have a bad relay. If no, then you have a problem with the wire between the relay box and the starter.

Hope this helps. If you need me to explain anything more, let me know.
Regards.
