I was sitting in my 1986 420SEL the other day, I had just started the car and was waiting for my wife to come out of the house. I decided while waiting to check the air pressure in the tires. As I got to the rear passenger tire I noticed a hissing sound. I listened carefully and am sure it is not from the tire. I was even more sure when I shut the car off and the hissing stopped. Could I have a vacuum leak? Are there any vacuum lines around there? Any other ideas, all locks are functioning fine
