Cheat both door switches, if it still alerts for the door then you have either a faulty switch or a firmware update needed. If it works check the corresponding activators on the door, the plastic covers could be snapped off.

That is the door switch for the side door. Those push button switches have been known to become faulty, especially in an environment where there is a high level of vapor or very small particles in the air which can get in the switch and contaminate the contacts. Also as ruben says, it could be the plastic flange that actuates the switch.

There was an engine update for the MP C2800/3300 to correct a false detection of cover open on the bridge unit. It extended the time necessary to detect cover open to compensate for momentary loss of contact due to vibration.

in sp mode you can also do input check on most of the switches to find the faulty one.
