Question about 2006 Jaguar XK8

1 Answer

Left 1999 XK8 in garage over winter months. Battery discharged. Recharged and reconnected. Have started car 10-12 journeys, and each ignition sounded like the battery was getting weaker and weaker. Battery is 2 years old and high quality. Battery incapable of holding charge now? Alternator not charging battery? Some horrible Jag electrics problem common after disconnecting battery? Very grateful for help, as I want to be able to trust it again!

Yes batterys can come apart inside. The plate breakdown and drop into bottom not allowing charge anymore. Low charge can do alot of weird things to you jag. Replace the battery and when you do have them check alternator charging ability while your there. Almost all auto store will do this for free.

Took car to garage on sat I had trouble windows didnt go up when started car battery flat charged it since then petrol light isonpetrol gaug stays red dash tells me the miles petrol i had how can fix

If the window problem is fixed then I would disconnect the battery for 10 minutes and then reconnect it. The ECU (the brain) might need re-setting and needs to re-learn a few settings. Drive around the block a couple of times and see if everything re-adjusts itself to normal. Bear in mind , though, that the memory for fuel consumption will have re-set so that short journey will be seen as the norm and it will give readings for mileage left worked out on that figure. A more economical journey will be worked out when you do one.

I left the key on the ignition switch for two days. The battery was discharged. However, after having recharged it, I have no radio, cabin light, or wireless central locking.

Sounds like it might have poped the main battery fuse, its in the main fuse box under the hood. some are slip in others are bolt in, Probably at least an 80 amp fuse, when u had it charged what the battery in the car or out,

Car won't turnover...only a clicking sound when turning ignition

A small battery charger may take 24 hours to charge your battery. If you are sure the battery is fully charged then you may want to clean your battery connections.

1999 Jaguar XK8 radio problem

You should reboot the system, sometimes these cars hicup so to speak.
Disconnect the battery, both sides, then with it still disconnected turn the key to crank 3-4 times (with the battery disconnected, this just discharges all the ecu's and clears any held memorys)
Reconnect the battery (pos + first)
After that you need to relearn the windows, with the key on or the car running send the windows all the way up, then one at a time, hold the button to bring 1 down and continue to hold for 5 seconds once it is all the way down, do the same for the up position, repeat on the other side and you should be good to go.

Fuel level indication problem

Try and reboot the system.
Disconnect both sides of the battery then crank the car 3-4 times (i know is sounds silly but this fully discharges all the ecu's)
Then reconnect the pos, then neg, reboot the windows and try that.
The xk8 have a lot of quirky problems like this.
