Was checking tire tread on drivers side and noticed that on looking at rear wheel arch a piece of the rear wheel well felt pad was missing when comparing it to the passenger side. Should both sides look the same, or has my back fender been replaced and felt pads not put back on, or has BMW it been done for a reason. Can someone check rear wheel wells to let me know. I live in a small country town with only a handful of BMW'S around and feel silly bending over to look at theirs and even more silly ringing a dealership to ask...
