When you lock the car the rear doors pin moves down but not all the way- only halfway. If you press the lock button again it sort of shivers but won't lower anymore. Door remains unlocked and the alarm is all working when you open it.
I have squirted a good dose of lubrication down the edges of the knob to see if it may have been catching but it's action is smooth and not sticking.
If you manually push the knob down and then lock the car on the fob it stays locked.
The lock is moving but not engaging properly.
The knob remains a cm above the door panel so it is obvious that the door is open I guess to anyone who is looking out for an open car to rob. Anymore ideas please?
Any idea how to get the rear door to stay locked manually and not respond to the fob? We generally never use the rear doors- two of us and the dogs in the boot.it would be a cheap fix I guess if we could leave that door locked u till you operated the rear interior handle.

EXACTLY the same problem, it must be an issue witht hese. Mine is the P3 V70 but its the same door, same problem, doesnt go all the way (only found out because the lad opened the door before i had chance to unlock).

Im convinced this coul dbe why my alamrs going off too

the issue isnt the motor, it moves fine, it must not be catching the pin right or the mechanism cant move freely. If not attached to the door it closes just fine so something over time is building up or drying out.

Do we have any door card removal pictures/techniques?
