If you know how to work on cars yourself, diagnose why it is giving you an electrical fault in the intake manifold.

The other two codes are a result of the intake manifold not working properly.

If you are not adapt at working on your own car get it to a good independent Mercedes specialist or the dealer..

Running lean for a long period of time can cause other down stream issues.
