Right basically here's the problem summed up in bullet points for ease of understanding!

-Both doors and boot locks with key.
-Drivers side and boot unlocks with key but passenger fails to do so. However it does make a whirring sound as if it should be unlocking!
-Using the central locking console inside the car unlocks and locks the drivers side and boot. But does nothing to the passenger side, neither locks nor unlocks.
-Hence the only way to unlock the passenger door it with the interior handle.

At first I thought it was the actuators unlocking mechanism, but then why does it lock with the key and not with the center console?

Any help please i'm lost! It was working fine till today and i only picked the car up 2 days ago..
