1982 300sd - intermittent heat
1982 300sd - heater blows warm for about 5 minutes then heated air turns cool. should i replace monovalve, then try solenoid that activates. turning heater to off then back on sometimes results in heat flowing again, but not always. turning car off then restarting returns heated air. i think malfunction in monovalve, but solenoid may be at fault as well. how do you diagnose which piece to replace or both? any sources for solenoid besides dealer?? i noticed you are sold out of solenoid

1979 300TD transmission vacuum controls???
Hi all,
I've got a 1979 300TD non-turbo that isn't shifting correctly. I'd like to start out with the vaccum system, but can't seem to come up with a schematic.
I've got Kent's transmission tuning manual, but the transmission in the 1979 wagon looks to be different than any of those explicitly described in the manual, and the vacuum schematics in the appendix don't seem to match either.
I've got two questions:
What is (and how do I test) the item labeled "B" in this picture? (I assume it's the VCV)

86 300D run-away engine
I have a 1986 124 300sd. I was changing out the glow plugs with the glow plug reamer kit available at MercedesSource, Awesome kit everything was a breeze lots of carbon build up. The problem arose on the test drive when the car accelerated uncontrollably! Upon close inspection I noticed that two hard fuel lines had been replaced, (by the previous owner) and in working the throttle linkage noted that ever so often the linkage rubbed on the fuel lines causing the throttle to stick in the open position.

1981 300TD-T Lack of Power
This 300TD-T has been running on Veg for about 3 years and 12k miles, I have owned it about 5 months. The rebuilt engine has 50k miles in it. Starting two weeks ago, the wife noticed a subtle power loss on hills and more white smoke than usual (this car has burned very clean except at start up). I drove the car last week, and tested it on a few residential hills in the neighborhood. At idle, the engine revs well…on the flats power is OK, but definitely not as strong as a few weeks ago… going up steep hills is impossible.

1975 300D Door Locks Repair
This weekend I repaired 2 doors using the rubber diaphragm kit from this website. However; on the front passenger door the pull/push knob stem seems to be dis-connected from the rod that is controlled by the actuator to lock and unlock door. Not sure what I need to repair, hard to see.
Also, I'm looking for the driver side door lock switch actuator that has the 3 vacuum lines, 1 in and 2 out but can't locate on this site.
