[Brian Gatehouse]

Good evening  2007 xk x150  weird problem, firstly my battery died . I replaced it then ABS fault DSC unavailable and engine lights came on, I had the codes cleared,  drove 100 yards they came back on. Changed the ABS sensors on the front. Cleared codes same issue came up after driving a mile DSC light started flashing car went into limp mode , brakes seemed to come on, and grinding noise heard, I stopped as soon as I could smoke was by then coming from rear N/S brakes which then went on fire. I managed to put the flames out but car is now stranded. Has anyone else experienced similar please ? Any help appreciated. Thank you.

Hi Brian, sounds quite serious, but I suspect they may well be electrical related - the battery on a Modern XK is a central part of its nervous system.

You say your battery "died", is the replacement new and fully charged? The faults you experienced with ABS, DSC, etc, are all symptomatic of a poor battery, unable to provide a stable voltage to the sensitive electronics.

It may be the case with brakes that the electronic parking brake (EPB) has been stuck on due to a poor signal associated with the battery condition, you are likely going to need access to a full Jaguar or Autologic diagnostic equipment to fully check and reset the brain of the car.

Good luck and please report back any progress.
