E320 Thinks My Passenger Door is Open

Hi,

I have an 2007 E320 and it's acting a little funny. Before I take it to the dealership, I wonder if I can fix the problem myself. A couple of days ago, the car started telling me that my right passenger door is open. It's obviously some sort of sensor issue because the door is completely shut. I can erase the message by hitting the reset button, but when the car slows to either a near/complete stop, the message alert kicks in again.

I don't mind ignoring it for awhile, but the problem has gotten worse. Now when I leave the car, the front light near the rear view mirror remains on. Regardless if I lock the door or leave it unlocked, it doesn't dim. If I stay inside the car and hit the light button, it will turn off. But if I leave the car and shut the door, the light stays on.

My only solution has been to leave my driver's side door open. But I have to work tomorrow, and I'm afraid that the light won't turn off and will drain my battery.

I assume the light stays on because it still thinks the passenger side door is open. Is there a solution? Is this a known problem? Any way to at least temporarily trick it into thinking the door is truly closed?

Thanks.

It maybe that your door contact switch failed.

Here's its location.

The switch is very easilly replaced. It pops out using small screwdriver in top slot and pry out. The switch is fairly cheap, worth trying.

Door open problem - any news

Hello - I have the identical problem after doing a door swap on my 2007 E320. I have changed over all the locks, control unit, and door handles as the old door had keyless entry even though this feature had never worked.
I was hoping that someone has found a resolution to this problem or can at least offer some suggestions? Many thanks.

Thanks

It was indeed the switch - I had not touched it but I had also failed to refit the plastic cover over the back of the lock which I can now see is essential to operate the switch. I am so pleased to be able to lock the car again. Thanks for your help.
