PM our in-house expert Mr. 240 3.0 DT.

 

The vacuum pump is actually on the front of the engine... I have the same problem in my 300TD... If I rev the motor a little bit before shut down, the vacuum builds up enough to lock the doors. The vacuum reservoir is located behind the back seat between the trunk and the back seat.

Are you having any other vacuum related issues such as the engine not wanting to shut off?

You can either have your vacuum pump rebuilt, or you can do it yourself. You can use a vacuum gauge to diagnose if you have a bad vacuum pump or not.

i apreciate the responses, i am not having any other vaccumn issues except with the door locks, the engine shuts off perfectly, not sure if this matters but when i lock the drivers door with the key the trunk locks too? but the other doors do not, i would assume that the trunk is a vacuum lock too? i apreciate your help, i really love my new to me car. and have got alot of complements on it
thanks

i think i found the problem, i got my parts cd in the mail, and went looking for the pump in the trunk and noticed, its not there, its missing , so that would explain my problem
sorry for bothering the board, i hope you don't think i'm crazy
