I recently picked up a 1992 300E California car with 145k. I love everything about it, and would love it more if everything worked. Right now Im trying to get the windows to close with the door key. The drivers windows will roll all the way down with one push, and all windows work perfectly at the switches. When I try the door lock trick, nothing. I have held the key (all 3 keys actually) in the lock position, nothing.
I've tried everything I've seen posted and recommended. Before I go and replace the CCM I was wondering if anyone had a new idea.
I also decoded my VIN, and I didn't see an option listed for this function. Can anyone tell me if this is something that is listed in the option codes? Perhaps my car just doesnt have the function.
I've also tried the "tunnel" functionwith the recirculation switch, and nothing there too.

One other problem, probably a bit more urgent, 10mpg!! The car runs strong, smooth, recently passed smog. Only issue is that if it has sat for more then an hour, I have to turn the ignition twice to get it to start. First try fires and dies immediately. Second try runs fine. Sounds to me like a faulty fuel valve leeking and loosing pressure to the injectors, but with this car nothing seems that easy, and I'm not sure if this explains the milage issue. I've never seen a puddle of fuel after the car has sat, so I dont think it's hemoraging gas.

Can anyone on this fine forum help a newbie out? FYI, I did spend hours going through the forums reading similar issues before posting. I just haven't found issues exactly like mine.
