Hello, I have an '81 240D that has been acting up. The engine will not stop running after the key is removed from the ignition. I have to go under the hood 95% of the time to push the STOP button to kill the engine. The other 5% I can kill it by shutting off the ignition and put it in gear. Another thing that began about the same time is the door lock will not lock the passenger doors when using the key in driver door.
This is my first M-B purchase a few months ago, and the electrical sys is unlike anything I'm used to. I'm sure this is a common problem - even though I did not see any related postings)
Regards, Terry
