HELP!!!!'

 

Mine froze once and after turning the ignition off, getting out, locking the door and walking away for a few minutes, it was back to normal. That ultimately turned out to be a weak battery. Problem has not returned since installing the new battery. Hope that helps.

 

I second the battery. I cured a whole host of electrical gremlins simply by changing the battery!

 

Yup, battery. See the very recent Jaguar xk Battery Replacement thread.

 

Ejected DVD re inserted problem solved!!!

 

Hopefully that was your problem...but you may want to have your battery load tested. It may allow you to head off many of the issues experienced with an inadequate battery.
