Key Chime?

My W208 does that... if the lights are on, it starts complaining... if the key is in the ignition, it does the same with a message on the console: "REMOVE KEY!"
Annoying, but useful...

Well, the reason I asked the question is because mine W201 does NOT have any sound when the door is opened but the key is in the ignition. I wanted to know if that was normal for that series.
