MC240D

I just recently got a 1982 240D that had been sitting for 10 years. Drained the fuel and oil, replaced all filters. Runs great... except for one thing. The motor won't turn off. Here where it gets strange, it will shut off if all the door locks are down (not kidding). The only way I can turn it off is to pop the hood or press all the door locks down and then turn the key. Any help would be appreciated. Thank you.

You have a leak in the "open" circuit of your central locking.

Thank you for the help. I'm swamped now with Christmas, I will check it out after the 25th! Any way to distinguish the open circuit?

Tracking down a leak is quite time consuming.

However, you may be able to isolate the area of the problem.

Block off the door lock system by plugging the rubber line that is attached to a yellow check valve. If the car shuts off like it's supposed to, your leak is in that system.
