240d Vacuum Leak
 

Changed Engine & Transmission and had vacuum and after running engine and driving the car for 20 miles the car had vacuum and the engine would shut off and then a short 5 mile drive and the engine would not shut off..Initially we did not get any response when we from door locks and front door would not lock with ket and now the front door vacuum works and the rest of the doors are trying to work...I know that we need to test with a mity vac but just wondering. We have isolated every system to see if their is vacuum and so far we have vacuum everywhere but some areas appear weak. Jim

Yes, you really need to test with a Mity-Vac. Be aware that even the lowly 240D manual HVAC setup has vacuum controls. So if you turned the air conditioner on or off during that 5 mile drive, it could have an effect. The HVAC vacuum is supplied by the green line with yellow stripe.
