I have a beater 01 E320 I am trying to figure out what I want to do with. It has 280k miles, has bad paint, and little body damage on one corner at the rear, but seems to run and drive pretty good. I am trying to decide if it is worth putting any time and effort into or not. One issue it has is the electronic ignition switch is flaky. If you put the key in and go to start it, it usually will not start if you turn the key. If you sort of push the key to the right and jiggle it, car starts. Once running, if the key gets jiggled again the blower motor and cruise control (for example) drop out. If you jiggle the key again you can get fan to come back on. Seems like an electrical contacts in the switch are bad or something. Can the module be repaired? I have another E320 parts car in the back. Can I swap the ignition module out and if so, what other modules need to be transplanted with it? May or may not be worth messing with on this car.
