guys please help, i have a 1995 c220, thats have a problem when i turn off the key; the dash light was blinking and all the relays blink... ...take the battery off and reconect turn on the car and ok, but at turn off the same problem return.

and need my car for go to my work

 

May not have anything to do with an MB...but my 1965 Ford Mustang developed the same problem. I found that by blowing the horn the engine would quit. Someone told me to replace the ignition switch. Being desperate I was able to do it myself and that fixed the problem. Don't ask my why or how. Magic? :-)
