Loud squeaking noise after I lock my car.

My car makes this loud squeak noise after I lock it. Sounds like its coming from the gas tank area. The noise is similar to the sound plastic makes when u over tighten it. Does anyone know what this could be or if its serious, it's really loud but only lasts like a second.

How can I tell if this is the issue? Whether the car is locked or unlocked i can open the gas tank door so there is no physical lock that I know of.

Do you use a global setup or selective-------Check your manual and look at the central locking system pages--------does it include a pnumatic gas tank flap locking device like most W210's
Actually you were right I locked it and saw a little silver thing come through the hole to the gas tank to try to lock it but it does not come out far enough to lock the tank. It must be jammed, is there anyway to unjam this?

Well the times i have managed to see the locking tang it doesn't even come out far enough to lock the door and other times it doesn't even come out when i lock the car. There is a hard circular plastic cap covering it can i remove that to have a better look inside?

However after your explanation I think it is faulty!!
What causes these things to go bad? I notice this noise just started happening after I had to unplug the battery to get into the trunk could this be related? Honestly before the noise i didn't even know the gas tank had a lock so it could have been broken when I got the car.

The other good news is that if you didn't know before------why worry about it know---fix it or forget it.

The bad news is that if you don't know the cars options and features---what else is wrong!!
I would have preferred an answer to my question but I guess your condescending sarcasm makes up for it...... also you spelled "now" wrong.

Then thirty minutes ago you ask a question about the lack of voltage (ELECTRICITY) that may have caused the problem plus you are not sure if when you purchased the car the problem existed----surely you kan answer that question or you are knot understanding my material!!
Congrats on moving further away from the point.
