Hi all I know this has been asked on here many time before and I have searched and read most threads about it. I have a 2004 54 octy tdi 130 all doors lock from the key and unlock fine. But if the fob is used it locks and unlock all doors bar the drivers door. Also the interior door lock button does not lock the driver door but all others. I have had the control unit out of the window housing and there was a little bit of water but not much and no rusted pins or loom. I cleaned both ends and still no joy. Then I have removed the lock unit to check for bad solder but none found I did resolder anyway. What I want to know is there anyway I can check if the door lock unit is working while I still have it out of the car? It has about 10 pin on the bottom of the unit am I able to power up with say a power probe a few pins on the bottom to test if the locking actuator is working or not?

Hi all okay I have lived up the motor out of the car using pins 1 and 2 and this operates the locking actuator so it looks like thhat is fine. But when I connect it into the car via the plug on the bottom of the lock it will not operate. I tested pins 1 and 2 and there is no live getting the only a earth pulse anyone have any idea as to where I should continue looking?
