Hello everyone, I just adopted a 1973 220D. It has a few problems that I need help on as this model and its accompanying nuances are new to me and all my service literature is for time periods before and after this car.

1) Won't shut off (Prior owner just bogged down in gear to shut-off). Everything appears to be intact with the exception of number 2 below which had no effect. Any common problems in this area on this particular car. It does not readily appear to be a vacuum leak.

2) Vacuum line from firewall (under driverside hood hinge) had an open connection as did the fitting off of the brake booster vacuum line. To diagnose, I ran some hose between the two to no avail. I also, in the alternative, simply plugged the one at the brake booster line also to no avail.

3) Had some diff whine, so I figured it wouldn't hurt to go ahead and check and change the fluid (I usually change all fluids right off the bat anyway). Had to suck out the fluid as I couldn't locate a drain plug and didn't feel like pulling the cover. This seems strange as even my 1967 had a drain plug. Did I simply fail to find it (car was flat on the ground so my maneuverability and vision was very limited)? FWIW, I didn't expect it to help my whine but at least wanted to make sure it wasn't being actively caused by old/low fluid.

4) I have holes but no headrests. What other years and models will fit? I need dark blue if anyone has any.


All advice appreciated.
