neto 190D: You are asking about a vacuum diaphragm?
I'm going to take a WAG.. Your engine won't shut
down with the key?
If so, he is the way you find out:
In your injection pump, the vacuum diaphragm which kills the engine is the one which has the fitting pointing parallel to the ground.
The vacuum line which serves it is a brown/blue
To check the system, first check for vacuum in the line. Run the engine for a minute or so. Cap off the brown/blue line.
Turn the ignition switch off and then with hose in hand, uncap it and you should hear a hissing sound. If you have a vacuum guage, obviously, use it for the test, you need a minimum of 10 inches to kill it.
To test the pump diaphragm, you can rig a vacuum line to a known vacuum source close to the main "T". Run the engine and with the line connected to the diaphragm, connect it to the good vacuum source, if it kill the engine, the diaphragm is good. If you have a hand vacuum pump it would be more ideal, because you could check the diaphragm for small leaks.
If the diaphragm is bad, it is easy to replace on the pump.
The shutoff diaphragm lists for $86.00
Is my shot in the dark correct?
Even though I am a Nissan Master tech, I also specialize in Mercedes-Benz and specifically Diesels, so if you need help, I'm here. I went through a few Mercedes Schools and have been swinging Iron in Mercedes since the 70's
I might be a little more informative than the public library.

Squirt some WD40 around the swtich to let it leak in behind. Wipe off the excess. Your window will work again. Done this several times on several old MBZs.

catalytic converter is clogged basically its stopping up your exhaust. Over time the pressure will slowly vent out, allowing your car to start, only to build up the backpressure again, stalling engine.

No brake lights or back-up lights fuses are good need wiring diagram


Its you headlight/bulb out indicator relay under the screwed down area behind your fuse box. Its longest relay in there. Failure rate for that age of vehicle is high for that part. Expensive new but cheap if you can get them froma bone yard. Also most W126 body styles have them also like the SEL's and SE's.

Mercedes Benz Model 200, year 1983


There aren't many people dealing with the W126 these days. The best place is ebay. Otherwise you could end up paying a small fortune at a specialist dismantler. But before you leap, look up the parts for the E class W124, many items were the same. Good luck
