This seems to be an unusual situation that does not fit with most of the threads I have read.
I have an '02 Jetta. Recently the alarm started going off seemingly randomly. Also, the 'door open' light would occasionally come on randomly while driving. I thought that probably the issue was a microswitch in the lock mechanism. A couple weekends ago I doused each of the door lock mechanisms with penetrating oil and then with contact cleaner. After that the 'door open' light worked completely consistently except at the driver door. With the driver door it would sometimes stay on, sometimes go off, and was definitely related to closing/slamming the driver's door. I sprayed it a bunch more and opened/closed it a bunch of times. After that exercise the 'door open' light now stays on constantly. One odd thing I noticed was that despite the 'door open' light being on constantly, the puddle light would turn on/off as it should when the door opened/closed as well as the door chime working properly when the key is in the ignition and the door is opened.
Now that the 'door open' light stays lit on the instrument cluster, the alarm does not arm when the doors are locked (no horn beep) and the random alarm going off no longer happens, so that's better but I would like to get it all working correctly.
Today I pulled apart the door and pulled the lock actuator. Even with the lock actuator removed, the door open light remains active. All three of the microswitches work correctly and have no effect on the 'door open' light. I pulled trim to get to the comfort control module. I also pulled trim by the hood release in order to get to the wiring connectors for the door. That all looks fine and unplugging them does not change the 'door open' light behavior.
I guess my next step is to plug in vag-com and take a look at what the comfort control module is doing.
Anyone have any other insight or suggestions (other than changing the lock module or micro-switches)?
