Likely your scan tool is not able to see all Mercedes codes. Solution if that’s the case is a more “friendly” Mercedes scan tool.

One DIY check........Make sure there are no electrical connections loose or unplugged especially on the air intake system. Second check ......no air leaks on the air intake system on the hoses and fittings. Especially the orange or black gasket on the front of the turbo intake.

Sticky on scan tools ...........several AUTEL models available at DIY pricing.

A long shot, but not hard to do. Check each and every fuse carefully. It doesn't happen often, but sometimes a blown fuse will produce odd symptoms.
