    "Door Open" message when door is closed

    in the driver icon dash area the message pops up saying my driver door is open when in fact it is closed, i usually have to open and close it repeatedly (15-20) times before the light goes away. Any idea on a simple fix?

    is it possible to wire in a resistor somewhere where it will fool the ecu into thinking the doors are always closed?

    also

    something else popped up (market ) something something on the dash and now my computer trip and mpg calculator are all in inactive and replaced with this messsage " ... market not set"

    thanks guys!

    I had a similar problem on mine 18 months ago, with the system not picking up the door was open (- when it actually was). It affects more than you think it does:
    - no interior/ footwell/ under-door lights;
    - no alarm triggering for that door;
    - no volumetric alarm active (- it needs to know you've opened the drivers door before enabling this);
    - door locks don't function properly;
    - you can get locked out!! (- I dis-armed the alarm and opened the door; put keys/wallet/mobile on the seat; closed door; then was talking at the back of the car. A minute later the alarm re-locks the car, as it doesn't know a door has been opened and thinks the dis-arming was an accident. Mucho time wasted getting the spare set from home....

    It turns out that in my case, the cause was bad contacts INSIDE the drivers door lock mechanism. I removed the door lock and stripped it down. The connectors that the wiring loom pushes onto, are only a 'finger connection' onto the circuitry, inside the lock unit. On mine, where the 'fingers' contacted the 'circuit board' there was some corrosion and poor connections. I lghtly sand-papered both sides back to clean metal, then carefully 'tinned' each side and soldered across the connection. No problems since. Re-assembling the lock was a bit fiddly though.

    Try doing a search on the word "latch". You should find a topic titled "Door Latch" about a year ago that has some details and pics of what you might expect.

    thanks for the reply guys, so this is what fixed it

    took the door panel off.

    took 220 grit sand paper, sanded all the metal around it.

    sprayed maf air flow sensor degreaser / cleaner all around it

    presto,

    Thats who i fixed mine, i removed the door trim and sprayed switch cleaner over the latch and no more trouble

    When a electricle problem crops up it is allways worth trying a quick squirt with switch cleaner . I brought my wife a Saab convertible very cheap becuse none of the window's would work neither would the roof, Saab quoted nearly a £1000 to fix it, I removed the switch pack in the centre consul and spayed it with switch cleaner and every thing worked, I still wonder today if that was what Saab would have done

    Switch Cleaner

    I am going to tackle this issue Sunday. Does anyone know what "swtich cleaner" is called in the US?

    I'd suspect the door ajar switch.

    Switch cleaner = contact cleaner

    Re: Switch Cleaner

    My RR is a later L322 but it came up with this message last night and wouldn't change ride height due to the imaginary open door. This morning I did the ECU reboot by disconnecting the battery for 10 minutes and that got rid of the message and the ride height is once again adjustable.

    Re: Switch Cleaner

    It may work on an L322 but all disconnecting the battery does on a P38 is cause you to have to reset the windows and sunroof, it doesn't reset any of the ECUs. The L322 uses a similar arrangement with microswitches in the door latch so you're going to be looking at a replacement latch in the near future.
