# Service bulletin ELW \-Intake Line

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 USA \(“MBUSA”\) is extending the coverage for the intake line assembly on your vehicle from the original New Vehicle Limited Warranty of 4 years / 50,000 miles to 15 years / 150,000 miles \(whichever occurs first\), and applies to the vehicle regardless of ownership. Why the warranty extension? On certain Model Year 2015 \- 2020 C/E/GLC/SLC and SLK vehicles, under certain circumstances, the partial\-load ventilation valve \(a part of the intake line assembly\) may not work as intended, resulting in the illumination of the check engine Malfunction Indicator Lamp \(‘MIL’\). A faulty partial\-load ventilation valve might also increase exhaust gas emission. . Any repairs under this warranty extension must be performed by an authorized Mercedes\-Benz dealership. • If your preferred authorized Mercedes\-Benz dealership performs a diagnosis and confirms that your vehicle has the issue, the repair will be performed at no cost to you. • This extended warranty does not apply to any other components or conditions beyond the ones mentioned above, and standard warranty terms apply, including the exclusions with respect to extra expenses, as identified in the Service and Warranty Information booklet. We hope you are enjoying your Mercedes\-Benz vehicle and we apologize for any inconvenience this may have caused.
