The problem
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.
The risk
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.
The fix
Dealers will recode the scn free of charge. The recall began on August 30, 2008. Owners May contact Mercedes-Benz at 1-800-367-6372.
