In the event of a vehicle crash, the electrical fuel pump may not receive a crash signal that is required for the fuel pump to disconnect and prevent future fuel delivery as designed.
Mercedes-Benz is recalling MY 2006-2008 M-class, R-class, MY 2005-2009 slk-class, MY 2005-2008 C-class, MY 2003-2004 and 2006-2008 clk-class, MY 2003-2008 E-class, MY 2004 and 2008 cl-class, MY 2008 cls-class, MY 2004 and 2007-2008 S-class, MY 2003 G-class, and MY 2003-2004, 2006 and 2009 sl-class vehicles. A software calibration number (scn) coding received on the affected vehicles during a recent workshop visit was incorrect. Depending on the model year and model affected, the results of an incorrect scn coding can affect a number of vehicle safety and emission functions including the following types of functions: (1) the fuel gauge readings may be incorrect; (2) a stuck fuel-level sensor may not be displayed in the instrument cluster; (3) the obd system may cause the check engine light to illuminate incorrectly; and, (4) the speedometer may be out of tolerance.
