wow this is very helpful indeed, thank you very much, i think you got this from Mercedes me?

 

When I drive off, the car locks all doors automatically. When the car comes to a complete stop, I notice the passenger cannot unlock the his door to get out unless the driver unlocks his door first, unlocking the central locking. How do we overcome this?

 

I get the same issue.

Seems to happen randomly, but whenever I try and open the passenger door (from the inside) first, it won't open. You have to use either the unlock button or open drivers door to unlock it.

I've been meaning to get mine to the dealers to have a look.

yes you can. press lock and then unlock buttons on your key and hold them until you see the led flashes. Now you will only open the driver door If you want open all you`ll have to press unlock button one more time. To reverse press the other way.
