I am having trouble with my 2003 XJ8 (x350) 4.2 SE. I had an intermittent problem where, occasionally, the steering column lock did not activate when the key was removed. This resulted in being unable to start the car again with a "Steering Column Locked" warning on the display. I found that by inserting and removing the key a few times, I could get the lock to engage then it would disengage when the key went in and all was well. Recently this fault got worse and ended up with the lock engaged and refusing to disengage at all. I concluded that either the locking mechanism itself or the Steering Column Lock Module within it had failed so I obtained a second -hand replacement and installed it. Unfortunately, although the column lock engaged when I first tried it, it still refuses to disengage.
Is there some sort of configuration needed for the replacement lock module - and, if so, how do I find out what is needed?
Is there a possibility that something has locked out and now needs resetting?
Some help would be much appreciated - the car is stuck on my driveway!!!
