E320 door lock beeping

try your owners manual, why would you want that obnoxious noise anyway?

Mine doesn't either, and I don't believe that they are supposed to (and I don't really like the "beep" anyway). The lights, however, do flash. Also, your remote does not have to be pointed at the car to lock/unlock the doors. It does need to be pointed at the car to unroll/roll up the windows.

Beeping is possible if your car is capable of handling Netherlands setting . Dealer setting only,not end user.

i dont like the beep so compromised by getting external blinker mirrors. those flash when doors un/lock

I don't like obnoxious noises, either, but as an aside, my navigator (lincoln suv) has no noise when you lock with the remote; however, if you press the lock button again within five seconds it will beep. This is useful if you are hauling kids, for example, as one beep will signal that all the doors, including the tailgate, are secured, whereas if it beeps twice, somewhere something is ajar. Nice to know, especially if you are parked in a less than desirable area with nice stuff inside. On the other hand, neither of my benz's makes a sound. But I love the green light on the door!
