Fitment notes
Researched from the part numbers and the donor car.
Sources: Based on the donor vehicle (2009 Mercedes‑GL‑Class GL350 Bluetec X164) and OEM platform sharing (GL‑Class X164 and R‑Class W251 share the same chassis and components), OEM parts catalogs and cross‑reference listings show part A 251 820 03 42 used on all GL‑Class X164 models (2007‑2012) and R‑Class W251 models (2006‑2012). / The supported applications are limited to the exact A0045429918/A2518200342 cross-reference shown in the cited fitment tables; the supplied 2009 GL350 is retained as an X164 application, while later GL listings are not generalized across the entire GL-Class because the sources identify later X166 applications separately. The search results did not substantiate the proposed GLE or GLS applications,.
