Just joined this forum.
I'm the owner of a 1990 W124 300 Diesel. The last 15 years the car did an outstanding job. It never failed and maintenance costs were surprisingly low! Recently problems started with stopping the motor. After turning the ignition key in the off position the motor is still running for a few more seconds. The time the motor is running despite turning the key in the off position becomes every day a little bit longer. I'm afraid that the moment is near that the motor won't stop at all.
It would be great if somebody could advise me how to solve this problem!
