Just wondering if you have solved your problem yet without having to spend more than the vehicle is worth.LOL
I may have a solution.

  1. If you can get the whole ignition assembly out (remembering that when you take off the rear -with wires connected to housing- make note of what goes where as best you can unless you have wiring schematics), place key into ignition and clamp vise grips to key.
  2. Place assembly into a bench vise so that the barrel is facing up and the vise grips clamped on key.
  3. With a ball-pen hammer (preferably heavy head) tap continously around the black casing, but not with too much force, but enough to send vibrations into the barrell. Good thing to do is to spray a lubricating solution down the barrel. Dont worry about the casing as it is a very hard metal.
  4. As you are tapping, hold the vise grips and put pressure on the vise grips as if you are turning the key to ON position, not too much pressure though. You might want to wriggle it. Do this holding the head of the vise grips and not the handle as you might twist the key and snap it in the barrel.
  5. This might take a bit of time so be paitient.
It took me about 15-20mins and all for free, well untill I get me a NEW barrel.
If you need further assistance I could try and send some pics of the step by step process.

SOURCE: 1988 Mercedes Benz - 300E , want to replace window switch

Hello, To the rear of the wood grain where the switches are, you should have a small piece of carpet that you just pull up and get it out of the way. You should see 1 screw. Remove the screw and gently pull up on the back of the wood grain. Now you will be able to change the switch.
I hope this helps.

First the sensor in the rear gearbox may be bad or corroded for sensing wheel speed. Also the engine wiring harness may be falling apart. From 1991-1995 the US made MB use biodegradable material on the wiring. When the insulation cracks you get shorts in the system. The same wires are in your EHA on the air inlet area. Check and replace as needed.

What are the schematics for wirinig an ignition for a 1991 300e mercedes benz? I am not sure what wire goes where when wiring my ignition

  1. The following fuses can cause the car not to start. Check and Replace fuses B, 5 and 6 and 7.
  2. Check the power to the neutral safety switch. When the ignition switch is activated there is no power to the neutral safety switch. Power to the neutral safety switch comes from the ignition switch on the violet wire. If there is no power at the violet wire when the key turns to start, the ignition switch is probably bad or there is a problem with the wiring to the switch.
