On the 2002-2009 Volkswagen Polo, the Polo IV (9N/9N3, 2002-2009) has a long-running, forum-documented weakness in its door lock modules: the microswitches inside the latch assembly (or their solder joints on the latch's small PCB) fail with age. The car then loses track of door status — a single door stops responding to central locking, the alarm LED fails to flash on locking, the dash shows a door open when it is closed, and in many cases the alarm self-triggers because the module falsely reports the door opening. The fault is intermittent at first and worsens over time. It is one of the most repeated topics on dedicated Polo owner forums (uk-polos.net) and affects driver and passenger doors alike.
Replace the affected door latch/lock module (typically $40-120 for the part plus 1-1.5 hours labor to strip the door card). Owners comfortable with electronics sometimes repair the latch by re-soldering the cracked joints on the internal PCB or replacing the microswitch itself for a few dollars. After replacement, verify the alarm LED flashes on locking and that the dash no longer shows a phantom open door.
