Service bulletin ELW-FuelFilter

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

In our continuing efforts to assure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, is extending the warranty coverage on the fuel filter unit in certain Model Year (“MY”) vehicles listed below from the original New Vehicle Limited Warranty of 4 years/50,000 miles to 15 years/150,000 miles (whichever occurs first) due to the following condition: The fuel filter unit might need to be replaced due to minor fuel seepage at the fuel filter flange that could result in fuel odor and/or an activation of the check engine Malfunction Indicator Lamp (“MIL”). Note that a risk of fire has been ruled out based on the nature of the fuel seepage and the distance to hot components. The vehicles will be visible and flagged in VMI as “OPEN” on June 10, 2022

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.
