Door lock issue…funny but annoying
My much beloved `05 XJ8 has developed an annoying issue.
When I start the car in P, I can lock the doors pressing the little handle above the large door handle and it locks.
And it unlocks with the small handle in the door handle fine as long as I have not moved from P to D.
I can also press the button in the dashboard and all the doors lock and unlock.
So far so good! Everything works as it should.
Now comes the funny part:
Once I set the gear lever to D all the doors lock as they are supposed to do. When I stop the car and put the gear lever back into P and want to open the drivers door, nothing happens. No door will unlock.
If you open any of the passenger doors, all doors will unlock and you can get out.
If you press the button on the dashboard all doors will unlock and you can get out.
If you press the the knob on the key fob, all doors will unlock and you can out.
But I can’t open that drivers door when I put the car back into P after the drive.
It can’t be the door handle mechanisms because as long as I have not put the car into D, everything works fine. Or can it?
Thanks for your input.

I have had a similar fault recently which is probably due to a failed
contact in the actuator (not the microswitch). These switches are integral with the actuator
and would not be easy to repair also the driver's door actuator (which is unique)
will be expensive to replace with new.
However after much thought (good for the brain at my age) there is
a solution and it's cheap!
This problem raises it's ugly head when you are inside the car
and need to open the driver's door which is locked due to driveaway locking.
Hence get rid of driveaway locking!
My local repairer had the software to do it for $80.
You may also find that after locking all doors with the remote
that you will need to unlock the driver's door only with a key.
I rarely lock my Jag so it's not a problem.
