    First off thanks to all the guys who've helped me so far with my list of e46 niggling problems.! You guys are great bunch.

    Ok, last on my list is the drivers door sensor. When I open the door with the lights on or keys in there is no warning sound, there is also no open door light on the car dash diagram. Interior lights also do not come on. I can only assume its the door sensor.

    How else can I test this? Is there a DIY? Is the door sensor integrated into the lock actuator?

    Cheers guys,
    Mcbonio

    I'm trying to figure out if the door lock and sensor are 2 separate parts? As the door locks fine mechanically and electronically.

    Anyone?

    Ok a quick update..
    It rained heavily all day today, when I got in my car the drivers door showed as open on the dash.. the sensor started working again.!

    Any ideas to why this might be guys? Why would it start working again?

    Ok its dried out and stopped working! Grr I can't figure this out. It's got to be the wiring. How do I removed the big wiring plug that goes from the door to the A pillar?

    dont know much about the sensor,

    but ther wireing plug, can easily be removed in the door jam, by un doing the (maybe 8mm) nut at the top of the plug and pulling it

    ok, the door sensor is working now, not sure how.. but it is. It's magically come back to life. Must be a fualty connection on the door pillar, as it seems to work once its rained...

    Go figure.!

    Well I hope this helps.

    The door sensor is integrated with the door lock actuator. The door open sensor has been known to fail. Though I don't see many.

    Check the connector (body to door), which you may have done.

    Pull the door card and waterproof seal off the door. Check the electrical connection of the door loom to door lock actuator. If the fault is still intermittant then suspect the door lock its self.

    I guess you have nothingto loose by removing the actuator and cleaning it. Though mostly the unit is sealed. The door closed sensor is a solid state switch and has no contacts.
