I had an interesting thing happen a few weeks ago that I'll share as FYI and ask for your advice on. I drive my D every day. One morning I went to start it and it just wouldn't start. Kept turning over but never catching. After a day and a half of worrying but not really even moving the car, I finally remembered to check on the intertia switch. Well the plunger was down, BUT one of the wires was disconnected! When I reconnected the wire the car operated perfectly. Of course my switch is in the original location near the lambda counter. So the moral is if your switch is in that location, be sure you can't accidentally disconnect the wires by kicking it or moving the floor mat accidentally. Also, if your car turns over but won't start and the plunger seems fine, double check the connection to the intertia switch. Now for my question. If I pull up the plunger manually to try to trip it on purpose to test it, nothing happens. I mean the car will start or continues to run just fine. Given the above this is wierd to me. I assume this means that my intertia switch is busted, but I just wanted to check if this is the behavior that a busted one exhibits. thanks, shiraz
