New Found Discovery

I think I may be the only diesel freak on here that did not know that 123's have a buzzer! Got out of church last night, went to fire the CD up and I heard this buzzing noise. I could not figure it out for a second or two cause none of the 123's I have ever owned had one that worked. Turns out it buzzes till the GP light goes off and also buzzes if the doors are opened and the key is in the ignition. The fact that it was near zero last night could have had something to do with it. I know one thing for sure, every Benz I have ever owned has had a different personality in the winter that they do in the summer. Anyone else experience this?

yup, not the glow plug light, but key in the ignition and the lights left on when door is opened.

Agreed. If you pay close attention when everything is working. The buzz will stop at a different time than the GP light. If it doesn't, it is pure coincidence. There is no noise associated with GP timing.

Seat belt buzzer

I found the seat belt buzzer especially annoying because I like to turn on the key and then buckle my seat belt (by the time I have the door locked and the belt on, the pre-glow cycle is over and I can start the engine). I got tired of listening to the darned buzzer and disconnected its switch.

There's a two-pin plug/socket on a cable under the front of the driver's seat. It's connected to a switch in the seat belt. Unplug it and you will no longer have a seat belt buzzer but the buzzer will still work for "key in ignition" and "lights left on."

Just unplug the seatbelt sensor. That buzzer has saved my @$$ on headlights more than once.
My other car turns out the lights for you.

So where's the seatbelt sensor? I too like to get the glowing started soon, then buckle up and get situated.

I can just barely hear my buzzer if it is dead quiet. Must be worn out after 22 years. I have had people tell me that my lights are on at my office because I forget to turn them off. Thank goodness I have never run my battery down.
