Hi there, so I have a 2003 a4 1.8L. My passenger door won't unlock when I use the remote but it will unlock if I use the key in the door or I hit the button on the drivers door. Everything else will unlock with the remote. Any ideas?

 

Press the unlock button twice in a row? If you press it once, it will only unlock the driver side door.

 

Yes even after I press it twice it doesn't unlock
