Hi I have 54 xk8 4.2 .
Few wks back I had flat battery .Put jump leads to start it .
Now its having problems .I now have use manual instead of auto .
Not changing going up with gears . The put into auto .Drives great on the motorway at 70 . .
Ive change the battery still no change .I had few codes came up . I had my local garage cleared the faults .I think they don't have tools to fix really .Ive called jag in perth .There head guy out .Call me back tomorrow Here are the codes
p0706
p1260
p1571
p1582


And garage advised me get a transmission service .Ask jag about it .They said not a lot people get that .
I stressed out about it because there nothing wrong before this happed .

On the end of the dashboard, near the door, on the driver's side, you will find a cover with a fusebox behind it. Remove the cover, and locate fuse #F16. The fuse numbers are embossed in the black plastic rail beside the fuses. The fuse itself will have a '5' on it, since it is a 5 amp fuse. Check if this fuse is blown and replace it if it is.

Report back here either way.

In the future, if you must jump the car, make sure the donor car is not running. The electrical system can be damaged otherwise.

 

jaguar-girl,

I've moved your question from General Tech Help to XK8/XKR forum. This is the place to post technical questions about your model.

I was going to say try a hard reboot ! But if you had the battery out with no power on the car to change it the it , it should have reset itself afterwards.
Hope the fuse trick works!

 

I took the leads off yesterday for hr .Still no change . I wish I saw my garage to start it . Got one the guys round to start it . Stupid question the fuses can get them from halford or do I have get them from jag or online .

 

Halfords should have the fuses, they are common types.

 

Also, there should be a few spare fuses taped to the underside of the cover of the other fusebox in the boot, near the battery (unless they have been removed already), courtesy of Jaguar.

 

I believe to do a hard reset you have to take the positive terminal off the battery and touch the ground wire with it. Just sitting may not do a hard reset. Search on the forum for Hard Reset. The Transmissions are sealed and although a lot of people do a flush and filter change I do not believe that has anything to do with your problem. I believe the fuse is probably the issue.

 

No ive not saw any spare fuses. I need say hello to them Don't think we meet yet .

 

Hi after breaking my nails for this so cauld fuse .I don't have no 16 . So I check both sides see if I'm daft and no So what number is it As in not happy and 1 in 6 people could swapped it .Just prove it here the photo both sides

 

Second photograph .... fuses are numbered 1-9 on right, and 10-18 on left. You don't have a 3 or 18 (which is correct).
So ................. 16 is the orange 5A between the white 25A and the blue 15A (7th down !)

Edit - under the lid of the big fuse box in the boot, not only are there spare fuses, but there should also be a little plastic gadget thingy to get fuses out of fuseholders without breaking nails !!! :-)

 

My dad drop off a fuse tester ,and found 1 fuse out No 5 , in the boot .Also found out I have fuses we tool get them out . Ow need cut my nails anyway .

Took out for wee run in drive think the computer is trying as was changing up . But few times it wouldn't . Think few runs hopefully fix it .


As I called jag early in the day they said it needed a software update .If not fixed 2 wks it be going there .


Thank you white xkr hopefully you save me lots cash
Feel bit chuffed think if fix my car for 1st time .

 

I hope you can find a competent repair shop so that you can avoid the dealer. I'm sure there are good ones, but as soon as they mention software upgrades and computer time I get nervous.

 

Ok! Do you know if the codes could be cleared and if so did they all come back?

As for the transmission you say it shifts properly in manual mode are you suggesting that you can put the shifter in 5th position and it shifts properly from start to normal speed but when you put it in “D” from a start it will not up shift. If this is true I would suggest that you have your shifter cable adjustment.

As for the other codes I would want to know if they cleared. A low voltage battery will give you erroneous codes that can put you in the wrong direction. As for jump starting your car I would suggest that you do not do that again.

 

Right this carry on about starting my battery .Ive never had flat battery any the cars ive had 26 yrs SO GIVE IT A BREAK RIGHT .Maybe the other jag guy should known better too .


All code were cleared yesterday . I rather take to jag .Then I know done right .
