Hi my screen has stopped working, all I get is the jaguar symbol blinking on and off intermittently and now have no radio, no proximity sensors, no reversing camera and no USB power, I tried to remove the disc in the boot and when I press the eject button nothing happens, maybe no power to that as well? BTW the car is a 2011 XF-S

Thinking maybe a battery disconnect and leave for twenty minutes and reconnect? I dont know how I should do this and concerned that I may lose more electrics, can anyone help? 

Many thanks in advance

 

Started the car this morning and its all working again???? Go figure! So 24 hours without anything now cleared? Will keep an eye on it.

Have recently read a similar post from a member on here and his response was the same....came back on and waiting for it to come back but no idea what was causing it.....keep us in the loop if it appears again and/or if you find the reason/rectification

Certainly will

My friend's XF had a similar issue. It was the Bluetooth/Phone module under the passenger seat that was causing the issue. It was water-damaged.

The Jaguar mechanic took it out and bypassed it in the car's software to allow the system to boot up.

Not had the problem since! 

Hearing a lot about water damage to the modules under the seat, it causes fault after fault! Assistive Dynamics fault has plaqued me for nearly two years but a mechanic I have recently started using said its a speed sensor on the rear drivers side which he will replace. He reckons this will solve a lot of the issues, we will see!
