As the title really.

I know the drivers door has a hidden barrel.

More info:

drivers side door loom replaced.

vcds says no communication to passenger door lock / window etc so it cant be opened electrically.

 

Also, is there a "door module" or are people who mention this  referring to the bcm?

If there is a door module and it cant be talked to am i correct in thinking only a dealer could program it ? 

 

There's a master door controller in the driver's door, with slaves in the other doors. They're separate to the BCM.

 

Are the rear doors functioning normally?

Thank you Chimaera. the rears were fine. it was a broken loom in the front passenger loom boot
