Question about 1989 Mercedes-Benz 300-Class

Engine Vacuum Diagram

I have recently acquired a 1989 Mercedes 300E with a 3.0 engine. It appears that the previous owner decided it would run better with most of the vauum hoses to the fuel distributor and intake manifold removed. I have tried everything, including shop manuals for a detailed diagram. Is there anyone out there that can help?

Turn off check engine light 1992 mercedes benz 300e


The check engine light is on for a reason. You need to pull the error codes, and resolve all of the issues indicated. Then the light will go off.

If a condition were to happen, and be intermittent, the light would go out....But your description appears to have a fault condition detected. It is better and less expensive to fix the issue(s).

I had a similar problem with my 1986 300e , which got progressively worse until the car was no longer driveable, I changed out the fuel pump relay and the problem went away.
