Left Rear Quarter Interior Trim - 2011 528i

When sourcing a left rear quarter interior trim for your 2011 BMW 528i F10, target 2010-2016 5-Series sedans (F10 chassis only; F11 Touring wagons use different rear geometry). Valid OEM numbers include 51 43 7 234 419 for black interiors and the superseding 51 43 7 452 667, though final digits indicate specific color codes. During junkyard inspection, check the three lower mounting tabs—BMW's brittle plastic retainers commonly shear off during rough removal, causing future rattles. Look for UV warping on the upper C-pillar edge and verify the door seal gasket hasn't bonded to the trim flange. Installation requires folding the rear seat, removing the C-pillar cover, and sliding the panel upward to release metal spring clips; never pry outward. Pre-LCI (2010-2013) and LCI (2014-2016) units interchange structurally but may lack cutouts for later ambient lighting packages. Always verify your specific interior color code, as BMW used varying suffixes for Oyster, Saddle, and Black variants.
