Drive side intermittent central locking

[m3tin]

Hi All,

I have A3 sline, just bought recently. Have noticed that on occasions when attempting to unlock driver door thru remote nothing happens, clicking on the remote again opens all other doors but again not the driver. repeatedly locking / unlocking seems to get it to unlock. I have changed the battery in the remote, and it seemed to resolve the issue. But again have noticed this happening infrequently. Any ideas would be much appreciated.

Thanks in advance folks
