Audi A6 Central Locking Problem

[Gert_8]

Hi All,

Anyone able to help me with the following please? My passenger front door locking system has stopped operating, i.e opening/closing doesn't work for this door using the remote or key. All other doors open/close fine.

I need to know what to look for regarding this problem, but more importantly how to get the door card off. I can't see any obvious places for screws etc, so they are well hidden.

Thanks in advance.
