Service bulletin Launch NCU 20200

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Mercedes-Benz AG (?MBAG?), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year 2018-2019 C and E-Class vehicles (205/238 platforms), an incorrect activated carbon filter might have been installed. In this case, the vehicle may not meet emission and certification requirements. MBUSA will conduct a voluntary Emission Recall Campaign in which an authorized Mercedes- Benz dealer will check the activated carbon filter, and replace it, if necessary.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
