Front Fender Liner/Splash Shield - 2011 528i

When scavenging BMW salvage yards for F10 5-Series front fender liners, target 2011-2013 528i, 535i, or 550i models to ensure pre-LCI compatibility before the 2014 facelift altered fender geometry. The critical OEM numbers are 51717186781 (driver/left) and 51717186782 (passenger/right), though verify your N52 naturally aspirated engine doesn't require the slightly modified N55 turbo variant with additional cooling duct cutouts near the intercooler piping. Inspect for cracks at the lower mounting tabs—these shear off from parking block impacts—and check the integrated engine undertray attachment points for stripped screw bosses. Installation requires removing the wheel and partially dropping the front bumper to access the upper fender bolts, working carefully around fragile headlight washer lines if equipped. Always compare the steering stop buffer mounting locations, as M-Sport variants utilize liners with reinforced air channels that differ from base models. Junkyard gems often hide in rear-collision total loss vehicles where front sheet metal remains pristine.
