Quick reference
Verify fitment for JDM vs USDM models, as there may be differences in parts; consult with a BMW specialist if uncertain.
Context
The 2011 BMW 528i, equipped with the N52B30 engine, features a right quarter window weatherstripping part number 51-71-7-184-931. When inspecting this component, look for signs of wear or cracking, as degraded weatherstripping can lead to water leaks and increased cabin noise. Installation typically involves removing the interior trim and carefully pulling out the old weatherstripping. Ensure the new part is seated properly to prevent future issues. This part is interchangeable with models from 2008 to 2016 within the F10 generation, but it’s crucial to verify any mounting bracket differences that may exist in specific model years.
