Sources: Based on OEM part listings on Amazon showing compatibility with X164 GL-Class (2007‑2012), W164 M‑Class (2005‑2011) and V251 R‑Class (2006‑2012) diesel V6 models. / Confirmed evidence identifies the exact 1649004101/A1645406501 front SAM across the X164 GL-Class, W164 M-Class and W251 R-Class platforms, but the available listings do not reliably establish the entire claimed model-year ranges or prove fitment to every diesel variant; the supplied 2009 GL350 is included, while later GL-Class years and the broad 2005-2017 R-Class claim are not accepted without V.
